Is This the Right Part?

✅ Cross Reference Information

Common Symptoms

• Heavy frost or ice buildup on the freezer evaporator area
• Refrigerator section becomes warm while the freezer remains relatively cold
• Freezer runs continuously or for unusually long periods
• Refrigerator or freezer stops cooling when the timer remains stuck in defrost
• Defrost cycle starts but the appliance does not return to cooling operation

Check Before Replacing

• Disconnect appliance power before accessing the timer, wiring, or nearby components.
• Inspect the timer connector and wiring for loose, misplaced, or damaged connections; do not rely on symptoms alone because the heater, defrost thermostat, and wiring can produce similar conditions.
• With power disconnected, inspect for excessive evaporator frost that could indicate a defrost-system problem.
• If qualified to perform electrical testing, verify the defrost heater and defrost thermostat separately before condemning the timer.
• A qualified technician may manually advance the timer into defrost and verify whether the compressor stops and the heater circuit is energized; live-voltage testing presents shock and fire hazards.
