This thermostat is a temperature-sensitive switch that controls power to cooling components as temperatures change. Replacing a worn thermostat restores consistent cycling and more accurate temperature regulation, helping the appliance maintain stable performance. What it does:

  • Senses temperature and opens/closes electrical contacts at set points
  • Regulates operation of key cooling components to maintain target temperature
  • Helps prevent overcooling, overheating, and erratic cycling
  • Failure signs include: no cooling, overcooling, temperature swings, unit runs continuously, or short-cycling
What's included:
  • 1 thermostat
Install notes:
  • Disconnect power before servicing; verify no voltage is present
  • Access the thermostat location; label/photograph wire positions and transfer one at a time
  • Install in the same position and orientation as the original to ensure proper thermal response
  • Restore power and confirm proper cycling and temperature control
