Maytag Microwave Error Code E5

E5 on a Maytag microwave, specifically models AMC5143AA* and MMC5193AA*, means the cooking sensor has detected a short circuit condition. The microwave stops operation when this fault occurs to prevent incorrect automatic cooking results. Letting the oven cool for 10 minutes is the first recommended step before further diagnosis.

The microwave halts operation when the E5 code appears, so continued cooking is not possible while the fault is active. It is advisable to leave the unit off until the cause is identified and resolved. Using a microwave with a faulty sensor could result in unpredictable cooking performance even if the unit were to restart.

Repair costs vary depending on what component has failed. If only the sensor needs replacement, parts and labor typically range from around $75 to $200 depending on your location and service provider. If the control board is found to be at fault, costs can be higher, often in the $150 to $350 range. It is worth comparing repair cost to the age and replacement cost of the unit before proceeding.

Unplugging the microwave and allowing it to cool for 10 minutes may clear the E5 code if the short was caused by elevated temperatures inside the cavity. If the code returns after the unit has fully cooled and been restarted, the sensor, wiring harness, or control board likely needs physical inspection and possible replacement. A reset alone will not fix an actual shorted sensor.

Start by unplugging the microwave and letting it cool for at least 10 minutes, then restore power to see if the code clears. If E5 returns, inspect the sensor and surrounding cavity area for moisture or food residue. If cleaning does not resolve the issue, the sensor or its wiring harness will need to be tested and likely replaced by a qualified technician.
