Fridge Thermostat: Estimated Price & Replacement Labour Cost
What It Does
The thermostat (or temperature control) monitors the internal temperature of the refrigerator and signals the compressor to start or stop accordingly. Mechanical thermostats use a temperature-sensitive capsule; electronic models use thermistors and a control board.
Why It Fails
Thermostats wear out with age, get stuck in the open or closed position, or lose calibration. A stuck-closed thermostat causes the fridge to run too cold or freeze food. A stuck-open thermostat prevents the compressor from running, causing the fridge to warm up.
Signs It Needs Replacing
- Fridge is too warm or too cold regardless of the dial setting
- Freezer is working but fridge section is warm
- Fridge runs constantly without cycling off
Estimated Part Cost
- Mechanical thermostat (universal/generic): $15 – $50
- OEM thermostat (Whirlpool, GE, Samsung): $30 – $100
- Electronic control board with integrated thermostat function: $80 – $250
Estimated Labour Cost
- Labour only: $75 – $150
- Full replacement (parts + labour): $100 – $300
DIY Potential
A mechanical thermostat is one of the more accessible DIY repairs on a refrigerator. It typically involves unplugging the fridge, removing a few screws, and swapping the unit. However, if the temperature control is integrated into an electronic control board, professional diagnosis is recommended first.
