Maytag Dryer Error Code F7

The F7 error code on a Maytag dryer indicates a motor sense failure, meaning the control board is not receiving the expected signal that confirms the drive motor is operating correctly. The motor sense circuit allows the electronic control to monitor whether the motor has started and is running within normal parameters. When this signal is absent or falls outside the acceptable range, the control board interprets this as a fault condition and shuts down the appliance to prevent damage.

The drive motor is responsible for rotating the drum and, in most configurations, also drives the blower wheel that moves heated air through the drum. A failure in the motor sense circuit can stem from several sources: a mechanically failed motor that will not start or stalls under load, a broken or loose wiring harness connection between the motor and the control board, a faulty motor start relay, or a defective control board that cannot properly read the motor sense signal even when the motor itself is functional.

Additionally, mechanical obstructions that place excessive load on the motor, such as a worn drum bearing, a seized idler pulley, or a blocked blower wheel, can cause the motor to draw excessive current and stall, triggering this fault. Diagnosing F7 requires systematically checking the motor windings for correct resistance, inspecting all wiring connections along the motor sense circuit, and verifying that no mechanical components are binding or restricting normal motor rotation.
