CRITICAL SAFETY WARNING: Unplug refrigerator before servicing. Wear cut-resistant gloves.

  1. Unplug refrigerator (or switch off breaker).
  2. Empty freezer section as needed and remove freezer shelves/bins.
  3. Remove the evaporator cover panel to expose the evaporator coil.
  4. Defrost ice buildup safely (use a steamer or warm air; do not chip with sharp tools).
  5. Locate the defrost limit thermostat clipped to the evaporator tubing.
  6. Disconnect the thermostat connector (or cut/splice if hardwired—use approved connectors and heat-shrink).
  7. Unclip/remove the old thermostat.
  8. Clip the new WG03F07360 firmly to the same tube location (good thermal contact is critical).
  9. Reconnect wiring and secure harness routing away from the heater and fan blades.
  10. Reinstall evaporator cover, shelves, and restore power.
  11. Confirm airflow returns and monitor temps over the next 12–24 hours.
  1. Test the thermostat cold (ice water): it should show continuity when cold and open when warm (spec varies).
  2. If the thermostat is open at freezer temps, it’s failed—don’t condemn the control board first.
  3. Always inspect the defrost heater and wiring for burn marks while you’re in the evaporator compartment.
  4. If icing returns quickly, suspect a defrost control issue (board/timer) or a door gasket air leak.
  5. Clip placement matters—wrong tube location can cause premature cut-off and repeat icing.
  6. Use a steamer; chipping ice often punctures the evaporator and totals the unit.
  7. If the drain trough is iced, clear the defrost drain to prevent refreeze and water leaks.
  8. After repair, verify the evaporator fan runs and the air damper (if present) isn’t stuck.

WG03F07360 Refrigerator Defrost Limit

The WG03F07360 is a genuine OEM defrost limit thermostat (bi-metal cut-off) used in select GE refrigerators. It’s a temperature-sensing safety/control device clipped to the evaporator tubing. During defrost, it opens at a preset temperature to stop the defrost heater once the evaporator is warm enough, preventing overheating and liner damage. When the evaporator is cold again, it closes to allow the next defrost cycle to energize the heater. Common failures are contacts stuck open (no defrost), stuck closed (overheating risk), moisture intrusion, or wiring fatigue at the leads. Symptoms: heavy frost/ice buildup on the evaporator, warm fridge temps, weak airflow, evaporator fan noise from ice contact, long run times, or repeated defrost-related faults. IMPORTANT: Match by model; GE uses multiple cut-off temperature ratings. CRITICAL: Unplug refrigerator before servicing; sharp fins and ice edges are common.
