Customer Questions and Answers for Thermostat by Whirlpool

This thermostat is a temperature-sensitive switch that helps your appliance regulate its cooling cycles for consistent performance. Replacing a failing thermostat restores proper cycling and helps prevent warm spots, overcooling, or frost buildup. What it does:

• Senses temperature and opens/closes an electrical circuit at a preset threshold
• Helps control components such as the compressor, fan, or defrost heater
• Common symptoms of a bad thermostat include inconsistent temperatures, unit running constantly or not cycling, heavy frost on the evaporator, or no automatic defrost
• May show signs of damage such as brittle leads or a deformed housing

• Disconnect power before servicing; turn off water supply if accessing near icemaker areas
• Note wire positions and transfer any clips/brackets from the original part
• Mount firmly in the original location so the thermostat senses temperature correctly; avoid pinching or stretching wires
• Restore power and verify proper cycling/defrost operation
