Maytag Dryer Error Code FP E2

The FP E2 error code on a Maytag dryer indicates a fault in the Coin 2 drop sensor circuit. This code is specific to coin-operated dryer models, where a sensor monitors the physical dropping of coins through the coin mechanism. The Coin 2 sensor is part of the payment acceptance system, and the control board expects a specific signal pattern from this sensor each time a coin passes through. When that signal falls outside expected parameters, or is absent entirely, the board logs the FP E2 fault.

The control board monitors the Coin 2 sensor through connection AA5. A fault in this circuit can stem from a blocked sensor path, a damaged sensor, or a wiring issue between the sensor and the board. Coins, lint, or debris can physically obstruct the sensor's optical or mechanical path, preventing it from detecting coin drops accurately. Corrosion or loose pins at connector AA5 can also interrupt the signal, causing the board to register a circuit error even if the sensor itself is functional.

Diagnosis should begin by inspecting the coin drop path for any physical blockage and clearing debris if found. After confirming the path is clear, the next step is checking the wiring and connector at AA5 on the control board for secure seating, bent pins, and signs of corrosion or damage. If the connection is intact and the sensor path is unobstructed but the fault persists, the Coin 2 sensor itself may have failed and require replacement.
