Maytag Dryer Error Code E2

The E2 error code on a Maytag gas dryer indicates a Burner Igniter Fault Count condition. Specifically, the dryer's control board detected that the 120V signal returning from the burner circuit did not transition down to 0V within the expected time window. Under normal operation, when the igniter activates and the gas valve opens, the flame sensor (also called the radiant sensor or flame detector) should cause the burner circuit voltage to drop as combustion is established. When that voltage drop does not occur within the predefined timing threshold, the control board logs this as a failed ignition attempt and increments a fault counter. Once that counter reaches its limit, E2 is displayed.

The components most directly involved in this fault are the igniter, the gas valve coils (including the radiant sensor coil and the hold coil), and the flame sensor. A weak or failed igniter is the most frequent culprit, as igniters degrade over time and may glow without reaching the temperature necessary to open the gas valve. A defective radiant sensor will also prevent the circuit from transitioning correctly, since the sensor controls whether the secondary gas valve coil remains energized. Gas valve coil failure, particularly in the boost or hold coil set, can produce the same symptom.

Wiring integrity between the control board and the burner assembly should also be evaluated. Loose connectors, heat-damaged insulation, or corroded terminals on the harness serving the igniter or flame sensor circuit can interrupt the expected voltage transition. Restricted gas supply, including a partially closed shutoff valve or low gas pressure, can allow the igniter to glow without sustaining a flame, which would also produce repeated failed ignition cycles and ultimately trigger E2.
