883712P Genuine Fridge Control Thermostat for Fisher & Paykel Fridges, Cabinet Temperature Thermostat, Packed Service Part

Fisher & Paykel's genuine control thermostat 883712P regulates cabinet temperature by starting and stopping the cooling cycle in line with the dial setting. It's one of several F&P control thermostats with near identical descriptions, including 883709P, and each suits particular models. With no model list on file, match the number on the old thermostat or your fridge's parts list, or send us the model and serial number to check.

Signs of a faulty fridge thermostat

Inside the thermostat is a small bellows linked to a sensing tube clipped near the evaporator or in the cabinet. As the temperature changes, the gas in the tube expands or contracts and flicks a set of contacts. Worn contacts or a leaking capillary leave the fridge either warm with the compressor sitting idle, or running constantly with milk and salad freezing. Some owners notice the fridge only works on the coldest setting. A multimeter across the terminals can confirm whether the contacts are switching.

Fitting tips for the thermostat

Switch off and unplug before removing the control housing. Take a clear photo of the wiring, then free the capillary tube from its clips, noting the exact position and depth it sits at. Feed the new tube into the same place without kinking it, reconnect the wires as per your photo and refit the housing. Leave the fridge running overnight on a mid setting and check the temperature with a thermometer.

Questions about this part

Can I use 883709P instead?

Only if your model's parts list allows it. The two share a description but carry different numbers, which usually points to a different temperature range or fitting. Check the number printed on your old thermostat and order that one.
