How the defrost and drain faults were resolved
Ice buildup and poor drainage were traced to two faults that had to be corrected together.
Ice buildup
Refrigerator Developed Ice Buildup and Defrost Problems
The appliance was not removing frost normally, creating ice accumulation and drainage problems.
Two faults found
Failed Defrost Heater and Blocked Drain Found
Inspection traced the fault to a non-functioning defrost heater along with an obstructed drain that could not carry meltwater away.
Defrost restored
Defrost Component Replaced and Drain Cleared
The failed defrost component was replaced, the drainage path was cleared, and the refrigerator was checked for normal defrost and water flow.
Why this matters
Restoring heat without clearing the drain could leave meltwater trapped, while clearing only the drain would not correct the failed defrost cycle.
