Samsung Microwave Code E-22: Temperature Sensor Shorted

Medium · inspection needed

Code: E-22
Appliance: Microwave
Brand: Samsung
Warranty: 30-day workmanship

What E-22 means

A short temperature sensor error is what E-22 stands for on Samsung US microwaves. The oven watches cavity heat through a sensor, and a short means the control sees that circuit as bridged, which gives a reading outside any normal range. The display holds the code and the heating modes that rely on the sensor will not start. Nothing in the message points to a spill or to how you were using the oven.

Common causes of E-22

A temperature sensor circuit shorted at the sensor or its wiring
Pinched or worn insulation on the sensor wires
Moisture across the sensor connection

✓ One safe check you can try

1. Breaker off, or unplug the oven. 2. Let the cavity and control area dry fully if anything got wet. 3. Hold for 60 seconds before you restore power. 4. Run a short test cycle on plain microwave with a cup of water. 5. Should E-22 appear again, request service.

! Why to stop there

The same code can come from a bad sensor or from a wire shorting somewhere along its run, so we check both.
We confirm the sensor reading against the cavity condition before ordering anything.
You approve the written price first, and the work carries a 30-day workmanship warranty.

Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

E-22E-22 questions

How do E-21 and E-22 differ?

E-21 means the temperature sensor circuit reads open and E-22 means it reads shorted. They point to opposite electrical conditions on the same circuit, so the fix can differ even if the reset steps are alike.

Could a hot cavity set off E-22?

Heat alone should not read as a short. If the code appears right after long cooking, let the oven cool and try again, and tell us if it keeps showing.

Is the oven safe to leave plugged in?

A code on its own is not a hazard, but you can unplug it if you prefer. Do not open the cabinet or the control area to look inside.
