All electric thermostats do exactly the same thing: “sense temperature.” They have a capillary tube with a bulb on the end. The bulb is located in a specific area on a piece of equipment.
When replacing a thermostat always remember two things:
- Shut off the power
- Replace the thermostat bulb into the location where it was
originally removed. If you do not put the bulb back in the same place you will have problems with hot spots and cool spots, especially in an oven.
Some thermostats are specific to a piece of equipment, so always check the temperature range of the thermostat before buying a new one.
Thermostats for fryersare very specific because of the snuffing box that is on the capillary tube. The snuffing box screws into the side of the fryer tank, and can vary in size by the fryer manufacturer.
Gas solenoids are found on a few pieces of equipment, most commonly on a griddle. The electric thermostat is connected to the solenoid. The thermostat opens and closes the solenoid valve, thus turning the gas flow on and off depending on the grill temperature.
