Maytag Dryer Error Code Upper dryer motor sense circuit error

The upper dryer motor sense circuit error indicates that the control board has detected a fault in the circuit responsible for monitoring the upper dryer motor's operation. In stacked or combination Maytag dryer units, the control board continuously monitors the motor sense circuit to verify that the upper dryer motor is running correctly. When this monitoring circuit returns an unexpected signal or no signal at all, the board logs this diagnostic code and disables the upper dryer's cycles and display until the code is manually cleared.

This fault can originate from two primary sources: a problem on the control board itself, or interference from the incoming power line. Power line interference, such as voltage fluctuations, surges, or noise on the electrical circuit, can cause the control board to misread the motor sense signal and trigger this code even when the motor hardware is functioning properly. A faulty or degraded control board may also generate false sense readings internally, particularly if components on the board responsible for signal processing have failed.

Because the upper dryer cycles and display are fully disabled when this code is active, the machine will not operate until the diagnostic code is cleared manually. The first step after encountering this error is to address any potential power quality issues, such as verifying the dryer is on a dedicated circuit and checking for signs of electrical surges, then clearing the code through the diagnostic menu. If the code returns immediately or after a short period of use, the control board is the likely culprit and should be inspected or replaced.
