Fridge or Freezer Regas and Repair: A South African Homeowner's Guide
There are few things as frustrating as discovering your fridge or freezer isn't working as it should. The immediate worry of spoiled food, combined with the stress of finding a reliable repair person, can feel overwhelming. In South Africa, where a working fridge is essential to beat the heat and navigate through load shedding, understanding the common issues and knowing when to call in a professional is key.
This comprehensive guide, based on insights from experienced appliance technicians across the country, will help you diagnose the problem, understand the repair process, and make an informed decision on whether to repair or replace your appliance.
Common Reasons Your Fridge or Freezer Isn't Cooling Properly
Before jumping to the conclusion that a regas is needed, it's worth checking a few simple things. Many cooling issues stem from easily overlooked factors that don't require an expert to fix.
- Incorrect Thermostat Settings: It sounds simple, but a fridge’s poor performance can often be traced back to an incorrect thermostat setting. Aim for around 3∘C to 4∘C for fridges and −18∘C for freezers.
- Dirty Condenser Coils: The condenser coils, usually at the back or underneath the fridge, are crucial for releasing heat. "In dusty areas like Gauteng, these coils get clogged fast," says David, a Kandua Pro in Centurion. "I had a customer who was convinced her fridge was broken, but it was just a thick blanket of dust on the coils. A quick clean had it working perfectly again."
- Blocked Air Vents: Modern fridges rely on internal air circulation. If food items or containers are blocking the vents, cold air can't circulate properly. Technicians often find large grocery boxes placed directly in front of a freezer’s internal fan, effectively blocking the airflow to the fridge section.
- Worn Door Seals (Gaskets): The rubber seals around the door keep cold air in and warm air out. If they are brittle, cracked, or loose, cold air will escape. You can test this by closing the door on a piece of paper; if it slides out easily, the seal might be compromised.
- Appliance is Overloaded: Stuffing your fridge too full can restrict airflow, preventing cold air from reaching all your food items.
When to Suspect a More Serious Problem
If the basic checks don't solve the problem, the issue might be a more complex internal fault that requires professional attention.
The Role of Refrigerant in Your Appliance
Your fridge cools by circulating a special chemical called refrigerant (often referred to as "gas") through a sealed system of coils. The compressor pumps this gas, which absorbs heat from inside the appliance and releases it outside. This continuous cycle keeps your food cold.
A lack of cooling, or the compressor running constantly without getting cold, is a strong indicator of a refrigerant leak. Since it's a closed system, a low gas level means there's a leak somewhere.
Other Common Internal Issues
Beyond refrigerant leaks, other components can fail and cause cooling problems:
- Faulty Compressor: The compressor is the "heart" of your fridge's cooling system. A failing compressor can make loud clicking noises, or the motor might not run at all. These repairs are best left to qualified technicians.
- Malfunctioning Evaporator Fan Motor: This fan circulates cold air inside the freezer and fridge. If it fails, cold air won't be distributed. Maria, a Cape Town-based Kandua technician, recalls a job where a solid block of ice had formed behind the freezer panel, completely obstructing airflow to the fridge section and causing the food to spoil.
- Defrost System Issues: If the defrost system fails, ice can build up on the evaporator coils, blocking airflow and preventing the fridge from cooling. This often looks like a thick layer of ice in the freezer.
The Repair Process: What a Professional Will Do
When you call an appliance technician, here is a general outline of what to expect:
- Diagnosis: The technician will first perform a thorough inspection, checking everything from the power supply to the condenser coils. They use specialised tools to diagnose complex issues like a refrigerant leak or a faulty compressor. Most technicians charge a call-out fee for this service, which typically ranges from R450 to R850. For more information, check out our appliance repair cost guide.
- Quotation: Based on their diagnosis, the professional will provide a detailed quote for the repair, including the cost of parts and labour.
- Repair:
- Fridge Regas: If a leak is detected, the technician will use specific equipment to locate and repair it. Only after the leak is sealed will they add new refrigerant. This process is complex and must be done safely and correctly, in accordance with South African national standards like SANS 10147, which governs the handling of refrigerants. A professional regas should last for the remaining lifespan of the appliance.
- Part Replacement: For a faulty thermostat, fan, or other component, the technician will install a new, quality-assured replacement part.
- Testing and Post-Service Advice: Once the repair is complete, they will test the appliance to ensure it is cooling correctly and provide you with tips on how to maintain it for optimal performance.
Risk of DIY vs. The Value of a Professional
While it’s tempting to fix your fridge yourself to save money, it can be extremely dangerous and lead to more expensive damage.
- Electrical Hazards: Working with electrical components without proper knowledge is a serious safety risk.
- Dangerous Chemicals: Refrigerants are potent chemicals that must be handled with specialised tools. Attempting a regas yourself is not only dangerous but also illegal in South Africa without proper certification from an accredited body like the South African Qualification and Certification Committee (SAQCC) for Gas.
- Voiding Warranties: A DIY attempt can void any existing warranties and may cause irreversible damage. John., a refrigeration specialist in Randburg with over 20 years of experience, shared a cautionary tale: "A homeowner used a 'DIY regas kit' with the wrong gas. It destroyed the internal seals of a high-end compressor, turning a potential R1,500 repair into a R10,000 replacement."
A professional technician has the specialised tools and knowledge to safely and effectively repair your fridge, ensuring the job is done right the first time.
Checklist: Post-Repair Care for Your Appliance
After a successful repair, a little maintenance goes a long way.
- Set the Right Temperature: Keep your fridge between 2∘C and 4∘C and your freezer at −18∘C.
- Allow for Airflow: Don't pack your fridge too tightly. Leave space for air to circulate freely.
- Clean the Condenser Coils: Every 6 to 12 months, unplug the fridge and use a vacuum to clean the coils at the back. This improves efficiency and prevents the compressor from overworking.
- Check Door Seals: Regularly inspect the door seals for any tears or gaps to prevent cold air from escaping.
- Be Cautious After Load Shedding: After the power returns, wait 5-10 minutes before plugging your fridge back in to protect the compressor from a power surge.
Customer Stories and Results
- The Cele Family, Durban: Their fridge stopped cooling just before a long weekend. "We thought all our groceries were a write-off," said Mrs. Cele. A Kandua Pro diagnosed a blocked defrost drain, cleared it within an hour, and got the fridge running again. "He saved us over R2,000 in spoiled food and saved our weekend plans."
- Priya, Sandton: Priya noticed her fridge was constantly running and her electricity bill was climbing. A full diagnosis from a Kandua technician revealed a slow refrigerant leak. The pro sealed the leak, regassed the system, and restored the fridge's efficiency. Priya reported a R250 drop in her monthly electricity bill.

Frequently Asked Questions about Fridge and Freezer Regas and Repair
Q: How much does a fridge or freezer regas typically cost in South Africa?A: A professional regas can range from R850 to R2,500. The final price depends on the fridge type, the amount of gas needed, and the complexity of finding and repairing the leak. This usually includes the call-out fee, labour, and parts.
Q: Is it worth repairing an old fridge or freezer?A: Generally, yes, if the repair costs less than 50% of a new one. If your appliance is over 10 years old and needs a major repair like a compressor replacement, it might be more economical to invest in a new, more energy-efficient model.
Q: How do I know if my fridge needs a regas?A: The main sign is the motor running but no cooling inside. You might also notice the compressor is running constantly without switching off. A technician can confirm if a refrigerant leak is the cause.
Q: What are the signs that my fridge compressor is failing?A: A loud buzzing or clicking noise from the back is a major red flag. Other signs include the fridge not cooling effectively or tripping your circuit breaker.
Q: What is the best way to clean the condenser coils?A: First, unplug the fridge. Then, use a vacuum cleaner with a brush attachment to gently remove all dust and debris from the coils located at the back or underneath the unit.
Q: How long does a typical fridge repair take?A: Simple jobs like replacing a thermostat take 1-2 hours. More complex work, like a compressor replacement or finding a slow gas leak, can take 3-5 hours or may require a return visit if specific parts need to be ordered.
Q: Is it normal for the outside of my fridge to feel warm?A: Yes, warm sides are normal, as this is where the condenser releases heat. However, if the sides feel excessively hot and the fridge isn't cooling well, it could signal a problem.
Q: Can I use a sharp object to chip away ice from my freezer?A: No, never. You can easily puncture the evaporator coils, causing a refrigerant leak and a very expensive repair. Always let the ice melt naturally during a manual defrost.
Q: Why is my fridge leaking water?A: It's usually a blocked defrost drain tube. During the automatic defrost cycle, water drains through a tube, and if it gets clogged with debris, the water will overflow and leak onto your floor.
Q: What is the average lifespan of a fridge or freezer?A: With proper maintenance, a good quality fridge or freezer can last 10 to 15 years. Regular cleaning and prompt repairs can significantly extend its lifespan.
Electricians in South Africa: what to know before you book
Electrical issues have a way of starting small… and turning serious fast. A plug that “sometimes trips” can become a melted socket. Flickering lights can point to loose connections. And if your earth leakage keeps going off, it’s often your home telling you something isn’t right.
Kandua helps you get it sorted by matching you with a vetted electrician for your job — whether it’s a repair, installation, inspection, upgrade, or an urgent call-out.
A few quick answers (so you don’t have to scroll)
How do I choose a good electrician?
Pick someone who explains the cause (not just the symptom), tests before they replace parts, prices transparently, and can issue the right compliance paperwork when it’s required.
Do I need an Electrical Certificate of Compliance (CoC) in South Africa?
Often, yes — especially for property transfer and for any additions/alterations to an installation. The Department of Employment and Labour has also warned against “paper CoCs” issued without proper testing, and urges homeowners to use legally registered electrical contractors.
What should electrical work cost?
Most electricians charge a call-out fee + labour + materials, with higher rates for after-hours, complex fault finding, DB work, or urgent callouts. (There’s a pricing guide further down.)
What should I do first in an electrical emergency?
If it’s safe, switch off power at the main breaker, keep people away from the affected area (especially if there’s water), and call an electrician. If there’s smoke/fire risk, treat it as an emergency immediately.
Common electrical problems (and what they usually mean)
You don’t need to diagnose like an electrician — but it helps to know what the usual “signals” point to.
“My plugs keep tripping / the power keeps going off”
Often caused by an overloaded circuit, a faulty appliance, a loose connection, or a problem at the DB (distribution board). If it’s frequent, don’t just keep resetting — you want proper testing to prevent heat build-up and damage.
“My earth leakage trips randomly (especially at night or when it rains)”
This can indicate moisture ingress, a faulty appliance, deteriorating insulation, outdoor circuits taking on water, or an earthing/bonding issue. It’s common — and it’s exactly the sort of thing that needs systematic fault finding.
“My lights flicker / dim when I use appliances”
Sometimes it’s a supply issue — but it can also point to loose connections, voltage drop, an overloaded circuit, or a stressed neutral. If you’re noticing it across multiple rooms, get it checked.
“I smell burning / a plug is warm / there’s buzzing at the DB”
Treat this as urgent. Heat + electrics is how small problems become big ones. Switch off the circuit (or main breaker if you’re unsure) and book an electrician.
“I get a small shock/tingle from taps or appliances”
That can be an earthing/bonding fault and should be investigated quickly — especially in kitchens, bathrooms, and anywhere near water.
When it’s a DIY job — and when it isn’t
DIY can be fine for low-risk, non-electrical basics (like replacing a light bulb, resetting a tripped breaker once, or unplugging an appliance to test if it’s the cause).
Call an electrician when:
- a socket/switch is hot, crackling, discoloured, or smells burnt
- breakers/earth leakage keep tripping
- you suspect faulty wiring, water exposure, or a hidden issue
- you’re touching the DB, adding circuits, or upgrading capacity
- you’re installing high-load appliances (oven, hob, geyser, heat pump) or adding dedicated circuits
- you’re adding solar/inverter equipment or changing the installation layout
- you may need a CoC for compliance, insurance, or sale/transfer
Certifications, registrations & compliance in South Africa (what matters and when)
This is the part people usually discover too late. Here’s the simple version.
1) Electrical CoC (Certificate of Compliance)
A CoC is a legal document confirming an electrical installation has been inspected and tested and is compliant. It’s commonly required before property sale/transfer, and it’s also required when electrical work involves additions or alterations.
Also important: the Department of Employment and Labour explicitly warns that a registered contractor may only issue a CoC after proper inspection/testing, and may not issue on behalf of an unregistered person.
2) “Registered person” (who is actually allowed to certify)
In practice, certification is tied to being a properly registered/authorised person (often referred to as a wireman’s licence / registered person in the industry). If you need a CoC, ask upfront:
“Are you legally registered to inspect, test, and issue the CoC for this work?”
3) CoC validity (the part everyone argues about)
A useful way to think about it:
- For transfer purposes, the regulations are commonly applied as “not older than 2 years”.
- For day-to-day living, it remains relevant until changes are made — if you alter/add to the installation, you’ll typically need a supplementary CoC for that work.
4) Solar / inverter / PV additions (very common now)
If you’re adding solar PV or inverter equipment, treat it as a compliance-sensitive electrical project. Industry guidance stresses that PV work should be under the supervision of properly qualified electrical persons, and the City of Cape Town’s guidance notes you should request the original electrical CoC from the registered installation electrician.
Pricing: what to budget for an electrician in South Africa
Pricing varies by city, travel distance, urgency, and complexity — but most homeowners will see a familiar structure:
Typical cost structure
- Call-out fee (travel + initial assessment)
- Labour (hourly)
- Materials/parts
- After-hours premium (nights, weekends, public holidays)
- Specialist testing / fault finding time (often where the real value is)
Typical ranges you’ll see (guideline)
- Labour: roughly R350 – R700/hour for many standard jobs (average often around the mid-range), with higher rates for specialised work.
- Emergency call-out: often around R600 – R900 (and may or may not include the first hour — always ask).
A realistic “small job” expectation
Even when it sounds simple, budget for a call-out + 1–2 hours labour plus parts. If you have a few small fixes, bundling them into one visit often saves money.
10 Genuinely helpful electrician FAQ's
- What’s the difference between “the power tripped” and “earth leakage tripped”?
A normal breaker trip usually points to overload or a circuit fault. Earth leakage trips when it detects current leaking to earth (often moisture, insulation breakdown, or a faulty appliance). If earth leakage trips repeatedly, it needs proper fault finding. - How do I figure out if it’s my appliance or the house wiring?
A safe starting point is to unplug high-load appliances and see if the trip stops — but if trips continue (or you see heat/burning smells), stop testing and get an electrician. The correct method is measured testing, not guesswork. - Why does my plug socket feel warm?
Warmth can mean a loose connection, overload, poor contact, or damaged wiring — all of which can create heat and become dangerous. Book it in sooner rather than later. - My lights flicker when I use the kettle/microwave — is that normal?
Occasional minor dimming can happen, but persistent flickering/dimming can signal voltage drop, loose connections, overloaded circuits, or neutral issues. If it’s happening across rooms, get it checked. - Do I need a dedicated circuit for an oven/hob/geyser/heat pump?
Very often, yes — these are high-load items and are safer (and usually more reliable) with correct isolation and wiring sized for the load. An electrician should assess and advise based on your DB capacity. - What’s involved in a DB (distribution board) upgrade?
Typically: inspection of existing circuits, correcting unsafe/incorrect connections, adding/replacing breakers, ensuring earthing and bonding are correct, labelling circuits, and testing. DB work should be done carefully and properly documented. - Do I need a new CoC after renovations?
If the renovation involved electrical additions/alterations (new circuits, moved points, new DB work, solar/inverter additions), you’ll usually need a supplementary CoC for that work. - How long does a CoC take to issue?
It depends on how many defects are found. A proper CoC requires inspection and testing — if repairs are needed, it may take longer. Be wary of instant “paper CoCs” with no testing. - Does an electrical CoC cover everything in the house?
A CoC generally relates to the electrical installation and its safety/compliance (distribution, wiring, earthing, bonding, etc.). If you have specialised systems (like solar PV or an electric fence), ask what additional documentation is required for those. - What should I ask an electrician before they start?
Three questions cover most issues:
- “What do you think is the likely cause, and how will you test it?”
- “Is this priced as call-out + hourly + materials, and what counts as after-hours?”
- “Will this work require a CoC or supplementary CoC — and are you registered to issue it?”
