Maytag Dryer Error Code IGNITION FAULT

The IGNITION FAULT code on a Maytag gas dryer indicates that the Direct Spark Ignition (DSI) system attempted to light the burner, monitored the gas valve return signal during the proof-of-flame window, and failed to confirm a stable flame within the allowed retry count. In a DSI system, the control board sends a signal to open the gas valve and fire the igniter simultaneously. A flame sensor or flame rod then feeds a return signal back to the control board to confirm combustion. If that return signal is lost or never received during the proof time, the board registers a failed ignition attempt and retries the sequence a set number of times. Once the retry count is exhausted without a successful reignition confirmation, the control locks out and triggers this fault.

When the fault is triggered, the dryer enters a controlled shutdown sequence: the drum continues to tumble and the system cools the load for approximately 3 minutes or until the internal temperature drops below 100 degrees Fahrenheit (38 degrees Celsius). After that threshold is met, the control shuts off all outputs and holds the fault state until the condition is addressed. This behavior is a safety measure to prevent uncontrolled gas flow or repeated failed ignition attempts without technician intervention.

The most common causes involve the gas valve itself, its return signal wiring, the flame sensor, or an interruption in gas supply. A failed gas valve coil may open the valve without producing a usable return signal. A dirty or cracked flame sensor rod will not conduct a proper flame signal back to the board. Weak gas pressure or a partially closed supply valve can allow partial ignition that extinguishes before the proof window closes, causing repeated retry failures. Wiring faults between the gas valve and control board can also simulate a lost return signal even when the hardware is functioning correctly.
