4055090155 Genuine Thermostat Assembly for Westinghouse Fridges WRM2400WD, Westinghouse Fridge Thermostat 1113209

If your Westinghouse WRM2400WD is running warm or freezing everything, the thermostat is a likely suspect. 4055090155 is the genuine thermostat assembly listed for that model, and its older Westinghouse number is 1113209. Supplied as an assembly, it's the control that switches the compressor on and off to hold the temperature you set. Check that the model label inside your fridge reads WRM2400WD before ordering.

Westinghouse fridge too warm or too cold?

A fridge thermostat senses temperature through a capillary or probe and closes its contacts when the cabinet warms, starting the compressor. When the contacts open again, the compressor stops. If they stick closed, the compressor runs without a break and food freezes in the fresh food section. If they fail open, the fridge stops cooling altogether while the light still works. A thermostat that has drifted can make temperatures swing or the fridge cycle oddly. Turning the dial and listening for a click is a quick first check.

Replacing the thermostat

Unplug the fridge first. Remove the thermostat housing, usually inside the fresh food compartment, and note where the capillary or sensor runs before pulling it out. Feed the new one along the same path, as its position affects the temperatures the fridge holds. Reconnect the wires exactly as they were, refit the knob and housing, and give the fridge a few hours to settle before checking temperatures.
