Maytag Microwave Error Code Err5

Err5 means the control board has detected a shorted touch panel. Your microwave has two touch panel sections, a top panel and a side panel, and the board monitors both for abnormal electrical signals. When it detects a short in either panel, it displays Err5 and stops normal operation to prevent further issues.

No, you should not use the microwave while Err5 is active. The error indicates a shorted touch panel, which means the control input to the board is compromised. Operating the unit in this state risks unintended commands being sent to the microwave, and the appliance will likely not function normally anyway. Unplug the unit until the fault is diagnosed and the defective panel is replaced.

Unplugging the microwave will temporarily clear the display, but Err5 will return once power is restored if the underlying shorted touch panel has not been replaced. The error is triggered by the hardware condition itself, not stored as a persistent fault code, so the board will detect the short again within about 30 seconds of being powered on. The only way to permanently clear Err5 is to replace the defective touch panel.

Start by unplugging the microwave. Locate the side touch panel connector labeled J5 on the display board and disconnect it. Restore power and wait 30 seconds. If Err5 disappears, the side touch panel is shorted and needs to be replaced. If Err5 reappears, the side panel is not the cause and the top touch panel should be replaced instead. Both parts are available as aftermarket or OEM replacements and can typically be swapped with basic hand tools.

A replacement touch panel for a Maytag microwave typically costs between $30 and $80 for the part, depending on the model. If you perform the repair yourself, that is your total cost. A professional appliance repair technician will add a service call fee and labor, often bringing the total to $100 to $200. Given that the diagnostic process and replacement procedure are relatively accessible, this is a reasonable DIY repair for someone comfortable with basic appliance disassembly.
