00232030 OEM Capillary Thermostat, Bulb and Capillary Tube Temperature Control for Cooking and Heating Appliances

Part 00232030 is an OEM capillary thermostat, an aftermarket part made to suit the original equipment specification. Capillary thermostats have a sensing bulb joined to the switch body by a thin tube, so the switch can sit well away from the heat it measures. No brand, model or temperature range is on file for this number, so compare it closely with your old thermostat before ordering.

How a capillary thermostat works and when it fails

Inside the bulb and capillary is a fluid that expands as it heats. That pressure acts on the switch, opening the contacts at the set temperature and closing them again as things cool. These thermostats are used in ovens, fryers, boilers and other heating appliances. A faulty one can leave the appliance not heating at all, running much hotter or cooler than the dial setting, or cycling on and off erratically. A kinked or split capillary lets the fluid escape, and the thermostat then stops controlling the temperature properly.

Checking and fitting a capillary thermostat

Isolate the appliance at the power point or switchboard first. Photograph the wiring and note how the capillary is routed before removing anything. Handle the new capillary gently and avoid sharp bends, which can crimp the tube. Fit the bulb back into the same clip or pocket so it reads the right temperature. Hard-wired appliances should be repaired by a licensed electrician.

Questions about this part

How do I know this thermostat matches mine?

Look for numbers and a temperature range printed on the body of your old thermostat, and measure the capillary length. Then compare the shaft, terminals and bulb size. If you're unsure, send those details and your appliance model through the parts enquiry form.
