22 C / 22 E

What causes it

Faulty defrost sensor or wiring.

What it means in practice

The refrigerator's defrost sensor isn't reporting correctly, so the control can't manage the defrost cycle. If it persists, frost can build up and cooling suffers.

What to check before calling

• ✓Power-cycle the fridge by unplugging it for 5 minutes.
• ✓If the code returns, the defrost sensor likely needs replacing — this isn't a DIY part swap.
• ✓Unplug the refrigerator for a few minutes to reset the control, then check whether the code returns.
• ✓Look for heavy frost on the freezer back wall, which suggests the defrost system isn't working.

When to call a technician

If the code returns or frost builds up, the defrost sensor or its wiring needs testing.

If those checks don't clear the 22 C / 22 E code, it's usually a sign of a failed part rather than something to keep resetting. A technician runs a full diagnostic on your refrigerator, confirms the cause, and quotes the repair before any work starts. The $89 service call is waived if you go ahead with the repair, and parts and labor are covered by our 90-day warranty on parts & labor.

Common question

Will food spoil with this code?

Not right away, but a failing defrost system can lead to poor cooling. Check temperatures and call if the fridge side warms up.
