The W11562215 is a genuine OEM defrost heater for Whirlpool, Maytag, and Amana refrigerators and upright freezers. This component is the primary heating element in your appliance’s automatic defrost system — it melts frost off the evaporator coils on a timed cycle to keep airflow clear and temperatures stable. When it fails, frost accumulates on the coils, blocking airflow and causing the fridge to warm up while the freezer may still appear cold. This is the exact OEM part your appliance was built with, ensuring a perfect fit and reliable defrost performance.

✓ Installation Tips

CRITICAL SAFETY WARNING: Always unplug your refrigerator before servicing.

1. Unplug the refrigerator from the wall outlet.
2. Empty the freezer compartment and remove shelving and drawers.
3. Remove the rear freezer panel to access the evaporator coils and defrost heater.
4. Manually defrost any ice buildup with a hair dryer or allow to thaw — do not use sharp tools.
5. Disconnect the heater wiring harness and remove the mounting clips or brackets.
6. Install the new W11562215 heater in the same position and secure with clips.
7. Reconnect the wiring harness.
8. Reinstall the rear panel, shelving, and drawers.
9. Plug in the refrigerator and allow 24 hours for temperatures to fully stabilize.

Tech Notes: Before replacing the heater, test it for continuity with a multimeter — no continuity confirms a failed heater. Also check the defrost thermostat and defrost timer/control board, as these are common co-failures. If frost returns quickly after replacement, inspect the defrost thermostat and door gaskets.

✓ Frequently Asked Questions

Q: My fridge is warm but the freezer seems fine — is the defrost heater the problem?
A: Yes — this is the classic symptom of a failed defrost heater. When the heater fails, frost blocks the evaporator coils and restricts airflow to the fridge section. See our guide: fridge too warm but freezer cold.

Q: How do I know if the W11562215 heater has failed?
A: Test it with a multimeter set to continuity or resistance. A working heater will show resistance (typically 20–100Ω depending on wattage); infinite resistance means the heater coil is open/failed and needs replacement.

Q: What does W11562215 replace?
A: W11562215 is the current active OEM part number and directly replaces the older W11340898. Both are functionally identical.

Q: Can I install this myself?
A: Yes — this is a straightforward repair. Access the evaporator coils by removing the rear freezer panel, swap the heater, and reconnect the harness. No special tools required. Always unplug the appliance first.

Q: Do you ship to Canada?
A: Yes — XPart Supply is based in Canada and ships fast across Canada and the US.
