Maytag Dryer Error Code E5

The E5 error code on a Maytag stack dryer indicates a Lower Burner Igniter Fault Count, meaning the control board has detected repeated ignition failures in the lower dryer pocket's gas burner system. This code is functionally identical to the E2 code but applies exclusively to the lower unit in a stacked configuration. The control monitors how many times the igniter attempts to light the burner without achieving a successful flame, and when that count exceeds the allowable threshold, E5 is triggered and the lower pocket is shut down to prevent unburned gas accumulation.

The ignition sequence in the lower pocket involves the igniter heating to a sufficient glow temperature, the radiant sensor (also called the flame sensor or igniter sensor) detecting that heat and allowing the gas valve coils to open, and then the burner establishing a flame. A fault in any part of this chain, including a weak igniter, failed radiant sensor, defective gas valve coils, or insufficient gas pressure, can cause repeated ignition failures that accumulate into the E5 fault count.

Because the lower pocket in a stack dryer can be more difficult to access than a standalone unit, diagnostics require careful disassembly. Technicians should measure igniter resistance and compare it against spec, test the radiant sensor for continuity and proper switching behavior, inspect the gas valve coil assemblies for opens, and verify adequate gas supply pressure at the burner. A worn igniter that reads in range at room temperature may still fail to reach adequate glow temperature under operating conditions, so resistance alone may not be conclusive.
