20 Common Fridge Faults That We Fix in Nairobi
A faulty fridge can spoil food, increase electricity consumption, or stop working completely. Best Fridge Repair fixes common refrigerator problems in Nairobi, including cooling failures, water leaks, excessive frost, electrical faults, compressor problems, damaged door seals, and refrigerant leaks.
Proper diagnosis is important because one symptom can have several possible causes. For example, a warm fridge may be affected by a faulty fan, blocked airflow, failed defrost components, low refrigerant, or a compressor problem. Our technicians inspect the appliance systematically before recommending the appropriate repair.
Common Fridge Faults We Repair
1. Fridge Not Cooling
A fridge that is not cooling is one of the most common reasons customers request fridge repair in Nairobi. The problem may affect the entire appliance or only the refrigerator compartment while the freezer remains cold.
Causes
Common causes include dirty condenser coils, a failed evaporator or condenser fan, a faulty thermostat, blocked air vents, a damaged door gasket, defrost failure, low refrigerant, or compressor trouble.
Diagnosis and repair
We check the temperature settings, airflow, door seal, condenser, fans, evaporator, compressor, and electrical components. If the condenser is dirty, it is cleaned. Faulty fans, sensors, thermostats, relays, or control boards are replaced. If the sealed system is affected, we test for leaks before carrying out any gas-related repair.
2. Freezer Not Freezing
A freezer may run without reaching freezing temperatures. Customers may notice soft food, melting ice, or longer compressor running times.
Causes
Possible causes include restricted airflow, excessive frost, evaporator fan failure, a defective temperature sensor, low refrigerant, or a weak compressor.
Diagnosis and repair
Our technician checks the evaporator frost pattern, fan operation, temperature controls, condenser condition, and compressor performance. Repairs may include clearing ice, restoring airflow, replacing the fan or sensor, repairing a refrigerant leak, or assessing compressor efficiency.
3. Excessive Frost Build-Up
Heavy frost on the freezer wall or evaporator cover can block air circulation and prevent cold air from reaching the fridge compartment.
Causes
The defrost heater, defrost thermostat, timer, thermal fuse, or electronic control board may have failed. A door that is left open frequently or has a poor seal can also introduce moisture.
Diagnosis and repair
We inspect the frost pattern and test each defrost component for continuity and correct operation. The appliance is safely defrosted, the failed part is replaced, and the drain and airflow passages are checked.
4. Water Leaking
Water may collect inside the fridge, underneath drawers, or on the floor. Leaking should be addressed quickly to prevent cabinet, flooring, and electrical damage.
Causes
The most common sources are a blocked defrost drain, frozen drain tube, damaged water dispenser line, cracked drain pan, overflowing tray, or an appliance that is not level.
Diagnosis and repair
We trace the source rather than simply wiping away the water. The drain is cleared, damaged tubing or trays are replaced, and the fridge is levelled correctly. We then test the appliance for further leakage.
5. Fridge Making Unusual Noises
Clicking, buzzing, rattling, grinding, or loud humming may indicate a developing fault.
Causes
Noise can come from a fan blade touching ice, loose covers, vibrating pipes, an uneven floor, a worn compressor, or a failing start relay.
Diagnosis and repair
We identify whether the sound comes from the compressor, condenser fan, evaporator fan, or cabinet. Loose parts are secured, ice obstructions are removed, damaged fans are replaced, and compressor or relay faults are tested.
6. Compressor Not Starting
The compressor is responsible for circulating refrigerant through the cooling system. If it does not start, the fridge may remain warm even though the lights and display work.
Causes
A defective start relay, overload protector, wiring connection, control board, unstable power supply, or mechanically failed compressor may be responsible.
Diagnosis and repair
We test the power supply, relay, overload, compressor winding resistance, and running current. A failed relay or overload is replaced. If the compressor is seized or electrically damaged, we explain the available repair or replacement options.
7. Fridge Tripping the Circuit Breaker
A fridge that repeatedly trips the breaker should be switched off and inspected by a qualified technician.
Causes
Potential sources include damaged wiring, a shorted component, moisture, compressor insulation failure, or a faulty power cable or plug.
Diagnosis and repair
We isolate the appliance, inspect the cable and plug, test components, and check for electrical leakage. The faulty wiring or component is repaired or replaced before the fridge is safely tested again.
8. Fridge Not Switching On
A completely dead appliance may have no interior light, display, fan, or compressor activity.
Causes
The problem can originate from the socket, plug, fuse, power cable, internal wiring, control board, or overload protector.
Diagnosis and repair
We verify the external power supply first, then inspect the appliance’s internal electrical path. Depending on the diagnosis, we may replace a fuse, repair wiring, replace the power cord, or install a compatible control component.
9. Damaged Door Seal
A torn, loose, hardened, or poorly fitting gasket allows warm air and moisture into the fridge.
Causes
Door seals deteriorate with age, frequent use, dirt, heat, poor alignment, or physical damage.
Diagnosis and repair
We inspect the gasket for gaps and test the door closure. Minor issues may be corrected by cleaning or adjusting the door. A damaged gasket is replaced with a suitable seal and checked for proper contact around the entire frame.
10. Fridge Overcooling
Overcooling may cause vegetables to freeze, drinks to become icy, or frost to form in the refrigerator compartment.
Causes
A faulty thermostat, temperature sensor, control board, blocked air damper, or incorrect temperature setting may be responsible.
Diagnosis and repair
We check the control setting, sensor response, airflow, and damper operation. The defective thermostat, sensor, or control component is replaced, and the temperature is tested after the repair.
11. Ice Maker Not Working
An automatic ice maker may stop producing ice, produce small quantities, or become stuck in one cycle.
Causes
Common causes include a frozen inlet tube, low water pressure, blocked filter, defective water inlet valve, failed motor module, sensor fault, or control board problem.
Diagnosis and repair
We check the water supply, inlet tube, valve, ice-maker mechanism, and sensor. Blockages are cleared and failed valves, motors, or control parts are replaced where required.
12. Water Dispenser Not Working
A dispenser may stop releasing water even when the fridge is connected to a water supply.
Causes
The water tank or line may be frozen or blocked. Other possibilities include a clogged filter, faulty dispenser switch, damaged valve, or low water pressure.
Diagnosis and repair
We inspect the water route from the inlet connection to the dispenser. The filter is replaced when necessary, blockages are cleared, and defective switches or valves are repaired or replaced.
13. Fridge Light Not Working
A failed interior light can make it difficult to see food and may indicate more than a burnt bulb.
Causes
The bulb or LED module may be faulty. The door switch, wiring, socket, or control board may also be affected.
Diagnosis and repair
We test the bulb, door switch, power connection, and lighting circuit. We then replace the bulb or LED module and repair any wiring or switch fault.
14. Temperature Fluctuations
Temperature fluctuations may cause food to spoil faster or create intermittent freezing.
Causes
Possible sources include a defective temperature sensor, unstable power, poor door sealing, blocked vents, overloading, dirty condenser coils, or a failing control board.
Diagnosis and repair
We check actual operating temperatures, sensor readings, airflow, door sealing, condenser condition, and power supply. The solution may involve replacing a sensor, correcting airflow, servicing the condenser, or repairing the control system.
15. Evaporator Fan Failure
The evaporator fan circulates cold air from the freezer through the refrigerator compartments. When it fails, the freezer may be cold while the fridge section is warm.
Causes
The fan motor may be worn out, blocked by ice, damaged by a foreign object, or affected by a wiring or control fault.
Diagnosis and repair
We listen for fan operation, inspect the blade and evaporator area, and test the motor and wiring. Ice is removed safely, and the fan motor or associated component is replaced if defective.
16. Condenser Fan Failure
The condenser fan helps release heat from the refrigeration system. A failed fan can cause poor cooling and excessive compressor heat.
Causes
Dust accumulation, a seized motor, damaged fan blade, wiring failure, or a faulty control board can stop the fan.
Diagnosis and repair
We inspect the fan, condenser, wiring, and motor. The condenser is cleaned, obstructions are removed, and the fan assembly or motor is replaced when necessary.
17. Faulty Thermostat
The thermostat controls when the compressor operates. A defective thermostat may cause poor cooling, excessive cooling, or irregular cycling.
Causes
Internal wear, burnt electrical contacts, inaccurate temperature sensing, or mechanical damage can cause thermostat failure.
Diagnosis and repair
We test the thermostat’s response at different settings and compare its operation with the fridge temperature. A defective thermostat is replaced with a compatible component and the cooling cycle is verified.
18. Defrost System Failure
A frost-free fridge depends on an automatic defrost system to prevent ice from covering the evaporator.
Causes
The defrost heater, thermostat, timer, thermal fuse, sensor, wiring, or electronic control board may fail.
Diagnosis and repair
We inspect the evaporator for abnormal ice accumulation and test the defrost circuit. After safely removing the ice, the failed component is replaced and the appliance is monitored through a cooling cycle.
19. Blocked Drainage System
A blocked drain prevents defrost water from reaching the drain pan. Water may then collect beneath drawers or freeze around the evaporator.
Causes
Food particles, dirt, ice, algae, and residue can block the drain opening or tube.
Diagnosis and repair
We clear the drain using suitable methods, inspect the drain tube, and check the drain pan. We avoid damaging internal tubing and confirm that water flows correctly after cleaning.
20. Refrigerant Gas Leak
A refrigerant leak can cause gradual loss of cooling performance. The compressor may run for long periods while the fridge remains warm.
Causes
Leaks may develop at joints, tubing, the evaporator, condenser, or areas affected by corrosion or accidental damage.
Diagnosis and repair
We inspect the sealed system and use appropriate testing methods to locate the leak. The leak is repaired, the system is evacuated, and the correct refrigerant charge is restored. Simply adding gas without finding the leak is not a lasting solution.

Frequently Asked Questions
1. Why is my fridge running but not cooling?
The condenser may be dirty, a fan may have failed, the evaporator may be blocked with ice, or the sealed system may have low refrigerant. A technician should inspect the appliance before any part is replaced.
2. How long does fridge repair take?
Simple repairs, such as replacing a thermostat, relay, bulb, or door gasket, may be completed during the first visit. Repairs involving refrigerant leaks, compressors, or difficult-to-access components may take longer.
3. Can a fridge with a gas leak be repaired?
Yes, in many cases. The leak must first be located and sealed, after which the system is evacuated and recharged with the correct refrigerant.
4. Why is my freezer cold but the fridge warm?
This commonly occurs when the evaporator fan is not circulating air, the air passage is blocked with ice, or the damper is not opening properly.
5. Why is water collecting under the vegetable drawers?
A blocked or frozen defrost drain is a common cause. Water may also come from a damaged drain pan or a water supply line.
6. Is excessive frost a serious fridge problem?
It can become serious because frost blocks airflow and forces the appliance to work harder. The defrost system should be inspected rather than repeatedly removing the ice without fixing the cause.
7. Why does my fridge keep tripping the power?
There may be a short circuit, damaged cable, compressor electrical fault, moisture, or another failed component. Disconnect the appliance and arrange professional diagnosis.
8. Should I replace or repair my fridge compressor?
The decision depends on the appliance’s age, condition, cooling system, compressor cost, and availability of compatible parts. We inspect the fridge and explain the practical options.
9. How can I prevent common fridge faults?
Keep the door seal clean, avoid blocking internal vents, maintain suitable temperature settings, allow airflow around the appliance, and arrange servicing when cooling performance changes.
