# Kenmore defrost system repair

### About defrost repair in this climate

The defrost system clears the frost that every damp door opening leaves behind, and in South Florida it never gets a quiet week. The parts are inexpensive on all three of the companies that build refrigerators for this badge; the labor of reaching the evaporator, and the discipline of testing heater, thermostat and control as one circuit rather than replacing them one at a time, is what the figure covers. The door seal is checked in the same visit, because a hardened seal will defeat a brand new defrost system within a season.

On this site the job covers refrigerators and freezers wearing the Kenmore badge, across Miami-Dade, Broward and Palm Beach. Tell us the three digits before the period on the rating plate when you book: they name the company that actually built the appliance, and on this badge that is where the diagnosis starts.

What this involves

Heater, thermostat and control tested as a circuit

The seal checked in the same visit, or it comes back

Ice that returns is the symptom, not the cause

Confirm it is the defrost circuit

Ice on the evaporator with a working compressor is the signature. We look rather than infer, which means the back panel comes off.

Test the three parts as one

Heater, terminating thermostat and the control that runs them. Two of the three commonly test fine and the third is the answer, and swapping blind gets that wrong.

Check the drain

A defrost cycle that works and a drain that is blocked puts water in the crisper. It is a different repair with the same starting complaint.

Find out why it was working so hard

Almost always a door seal or a door that is not closing square. Repairing the circuit and leaving that is a repair with a return date.

Watch a cycle before we leave

A defrost circuit that has been repaired has not been proved until it has run.

### I defrosted it manually and it works again.

Then the defrost system is not running and it will ice up again on the same schedule. Manual defrosting is a good diagnosis and a poor repair.

### Is this worth doing on an older refrigerator?

Usually yes. This is one of the repairs where the parts are genuinely cheap on every builder behind this badge, so the arithmetic favors fixing it for longer than it does on a sealed system.
