Whirlpool Refrigerator Defrost Heater Assembly W11650659 – Superseded by W11573115

Is This the Right Part?

Common Symptoms

• Freezer evaporator coils heavily frosted or iced over
• Refrigerator or freezer not defrosting normally
• Refrigerator runs for unusually long periods
• Freezer cooling is reduced because ice blocks airflow
• Fresh-food compartment is warm while the freezer remains cold

Check Before Replacing

• Disconnect power before accessing the heater assembly or wiring.
• Visually inspect the evaporator area for excessive frost or ice buildup; this symptom alone does not prove the heater is defective.
• With power disconnected and the assembly safely accessible, a qualified person may check heater continuity with a multimeter; an open circuit indicates the heater assembly may be defective.
• Use the refrigerator’s model-specific service diagnostics, if available, to test the defrost-heater circuit; do not perform live-voltage testing unless qualified and following the appliance tech sheet.
• Check the heater harness and connectors for visible damage, loose connections, or signs of overheating.

Installation Notes

• Disconnect electrical power before servicing.
• Use the appliance’s model-specific service documentation and verify fitment before installation.
• Protect the evaporator tubing and wiring while removing or positioning the assembly.
• Reconnect the harness exactly as the original assembly was routed and connected; do not alter connector locations or wiring routing.
• After installation, confirm that connectors are fully seated and that wiring is clear of sharp edges, moving parts, and the evaporator fan.
• Do not force frozen components; allow ice to thaw using a safe method appropriate for the appliance before attempting removal.
