Maytag Dryer Error Code 25

Error code 25 on a Maytag dryer indicates that the control board detected a failure in Rotary Switch 1, positioned to the left of the encoder, during the startup sequence. This switch is part of the user interface assembly and communicates cycle selection data to the main control board. The fault is flagged at startup, meaning the board runs a self-check before the cycle begins and finds that Rotary Switch 1 is not returning a valid signal. This points to a problem within the selector switch mechanism, its wiring connections, or the control board itself.

For homeowners, this means the dryer's main dial or cycle selector is not communicating properly with the control board. When you attempt to start a cycle, the board checks that each component of the selector switch system is working correctly. If Rotary Switch 1 fails this check, the dryer will not proceed and will display error code 25 instead. The dryer is protecting itself from running a cycle with an unknown or invalid setting.

Because this error appears at startup rather than mid-cycle, the fault is likely consistent and repeatable. Resetting the dryer by unplugging it for one minute and restarting is worth trying first, but if the code returns immediately, the switch or its wiring will need physical inspection.
