Whirlpool Refrigerator Repair (Model GB22DKXGW00) – Canton, OH

A Canton homeowner called about their Whirlpool refrigerator (model GB22DKXGW00) running warm in the fresh food section while the freezer stayed cold. We found a failed defrost thermostat had caused the evaporator coil to ice over, blocking airflow between compartments.

The Problem

The customer reported that their garage-located refrigerator’s fresh food section wasn’t cooling properly, though the freezer compartment maintained normal temperatures. Food items in the refrigerator section were spoiling due to inadequate cooling, creating an urgent repair situation.

Diagnosis

Opening the freezer revealed an evaporator coil completely packed with frost buildup. The evaporator fan was running but couldn’t circulate air through the ice blockage. Testing the defrost thermostat showed it remained open even when cold — a clear failure that prevented the defrost cycle from running. Without periodic defrost cycles, frost accumulated until it blocked all airflow from the freezer to the fresh food section.

The Repair

• Parts replaced: ML50 — defrost thermostat
• Work performed: Removed old thermostat, cleared frost buildup from evaporator coil, installed new defrost thermostat
• Result: Defrost cycle now functions properly, temperatures normalized in both compartments

Is It Worth Repairing?

This GB22DKXGW00 is a solid Whirlpool side-by-side that typically runs 15+ years with proper maintenance. The defrost thermostat failure is a common wear item, not a sign of broader problems. Given the relatively simple repair and the unit’s reliable design, this repair makes good financial sense for most homeowners.

Maintenance Tips for Whirlpool Refrigerators

• In garage installations, ensure ambient temperature stays within the unit’s operating range (typically 55-110°F)
• Keep the door gaskets clean and check for proper sealing — garage dust can compromise the seal
• Vacuum the condenser coils underneath every 6 months in dusty garage environments
• Monitor for unusual frost patterns in the freezer, which can indicate defrost system issues
