When a technician says a part needs replacing, it helps to know what that part does and whether the diagnosis makes sense. These are the fridge parts we replace most often, the signs they are failing and what replacement involves.
Fridge Parts That Commonly Need Replacing: The Short Answer
The fridge parts most often replaced are door seals, evaporator and condenser fan motors, defrost heaters and sensors, thermostats and temperature sensors, water inlet valves, control boards, and compressor start relays. Compressors fail less often but are the most significant repair. Shelves, bins and drawers are also commonly replaced as they crack with use.
8 Parts That Commonly Need Replacing
1. Door seals (gaskets)
Signs: condensation, frost near the door, the paper test failing, the fridge running longer. Seals harden and split with age and cleaning chemicals. See fridge door problems.
2. Evaporator fan motor
Signs: fridge warm while the freezer is cold, squealing from the freezer, no airflow from vents. See freezer fan not working.
3. Condenser fan motor
Signs: fridge warm, compressor very hot, poor cooling in hot weather. See condenser fan problems.
4. Defrost heater, thermostat or sensor
Signs: heavy frost on the freezer back wall, fridge warming, water under the crisper. See fridge defrost problems.
5. Thermostat or temperature sensor
Signs: fridge too warm or freezing food, temperature swings. See faulty thermostat symptoms.
6. Water inlet valve
Signs: no water or ice, slow dispensing, leaks behind the fridge. See water dispenser not working.
7. Electronic control board
Signs: no power or display, error codes that will not clear, erratic behaviour, often after a power surge. See fridge error codes.
8. Compressor start relay and overload
Signs: clicking every few minutes with no cooling. These small parts often fail before the compressor. See signs of a bad compressor.
Also: shelves, bins and drawers
Door bins and crisper drawers crack with use. Genuine replacements are usually available for current models.

What About the Compressor?
Compressors can fail, but they are replaced less often than the parts above. Many “compressor” faults turn out to be a relay, fan or board. Compressor replacement involves the sealed system and must be done by an ARC-licensed technician. See our repair vs replace guide for when it is worth doing.
Genuine vs Generic Parts
Genuine or quality parts matched to your model generally last longer and fit correctly. Ask your technician what parts they will use and what warranty applies.

Frequently Asked Questions
What fridge parts fail most often?
Door seals, fan motors, defrost components, thermostats and sensors, water inlet valves, control boards and compressor start relays.
Is it worth replacing a fridge part rather than the whole fridge?
Usually, yes, for single-component faults. Replacement of the whole fridge is mainly worth considering when the compressor or sealed system fails on an older fridge.
Can I replace fridge parts myself?
Shelves, bins and water filters, yes. Electrical parts and anything in the sealed system should be replaced by a qualified technician.
