Description

This bimetal limit switch is a temperature-controlled defrost thermostat that helps stop the defrost heater once the evaporator reaches the proper temperature, protecting the system and supporting reliable defrost cycles. What it does:

• Opens and stops the defrost heater when the evaporator reaches the cut-out temperature
• Closes to allow the heater to run during defrost when temperature falls below the cut-in point
• Helps prevent excessive heating and ice buildup on the evaporator
• Commonly replaced when a unit fails to defrost, has persistent frost buildup, or shows erratic defrost cycles

What's included:

• One bimetal limit switch

Install notes:

• Disconnect power to the appliance before attempting any repair
• Typically mounted near the evaporator or defrost heater; handle with care to avoid bending terminals
• Test with a multimeter for continuity to confirm failure before replacing
