Maytag Dryer Error Code E1

The E1 error code on a Maytag gas dryer indicates a Radiant Sensor Fault Count. This fault occurs when the dryer's control board attempts to ignite the burner assembly but never receives a confirming 120V return signal from the radiant sensor within the expected time window. The radiant sensor is a heat-sensitive switch mounted near the burner that closes when it detects the infrared heat of an active flame. If the burner fires and the sensor does not confirm flame presence within the predefined timeout, the control board logs this as a fault and triggers the E1 code.

The radiant sensor plays a critical role in the ignition verification loop. When the control sends voltage to the igniter and gas valve, it simultaneously monitors the radiant sensor circuit for a return signal confirming that combustion has occurred. A failure anywhere in this loop, including a faulty sensor, a broken wire harness connection, a failed igniter that never gets hot enough to open the gas valve, or a gas valve coil that fails to open, can prevent the 120V return signal from arriving at the control board.

Common root causes include a defective radiant sensor that no longer responds to heat, a failed igniter that glows weakly or not at all, burned or corroded wiring between the sensor and control board, or gas valve coils that have failed open or closed. Because this error specifically tracks repeated failed ignition attempts, it can also appear when gas supply issues prevent the burner from lighting consistently, though component failure within the dryer itself is the more typical culprit.
