Dead heater stops defrost cycle — frost accumulates until coils fully blocked
Blocked evaporator coils restrict airflow to fresh food section causing temperature rise
Open-circuit heater means thermostat never reaches cutoff — defrost cycle is effectively disabled





💡 Pro Tip: Confirm the Heater Before You Buy
Your part is likely the culprit if you notice any of the following:
⚠️ Heavy frost or solid ice on the freezer back wall or floor
⚠️ Refrigerator section warming while freezer still feels cold
⚠️ Both compartments gradually warming — full coil blockage
⚠️ Defrost timer cycles but no warmth felt on the evaporator coil
Multimeter set to continuity. Unplug the fridge, access the heater behind the freezer back panel, disconnect both leads, touch probes to terminals. No continuity means the element has burned open — replace the heater. If continuity is present, check the defrost thermostat and timer before spending on parts.
