# GE defrost system repair

What this involves

Heater, thermostat and control tested as one circuit

Humidity makes this the local failure

Ice that returns after a manual defrost is this

Confirm it is defrost and not airflow

A manual defrost that restores cooling for a few days and then loses it again is the signature, and it is worth knowing before parts are ordered.

Test the heater and the thermostat

Both fail in ways that look identical from the front of the appliance and cost different money.

Check the drain path while it is open

A defrost drain that has iced over sends water to the floor of the cabinet, which is how this repair and 'water under the crisper' turn out to be the same visit.

Replace, then watch a full cycle

The circuit only proves itself over a cycle, so we let it run rather than closing up on a reading.

Why we watch a full cycle

The circuit only proves itself over a defrost cycle, so we let it run rather than closing up on a resistance reading. It is the difference between the repair holding and the same call in a fortnight.
