Maytag Dryer Error Code D15

D15 is a Lower Burner Return Voltage Fault that appears on Maytag stack dryers. It means the control board did not receive the expected voltage confirmation signal from the lower pocket burner circuit. This code indicates a problem with the lower unit's heating system, which can involve the radiant sensor, gas valve coils, igniter, or wiring. The upper drying pocket may continue to operate normally while this fault is present.

The D15 fault causes the control board to disable or interrupt the lower burner operation, which is a protective response. You should not attempt to bypass the error or force the appliance to run while the fault is active. If you smell gas at any point, turn off the gas supply immediately and contact a qualified technician before using the dryer again.

Resetting the dryer may temporarily clear the D15 code, but the error will return if the underlying fault in the lower burner circuit is not corrected. A reset does not repair the failed component or wiring causing the fault. It is recommended to complete a proper diagnosis before resetting, so the fault condition can be identified and resolved permanently.

Some causes of D15, such as a loose wiring connector in the lower burner harness, can be addressed by a knowledgeable DIYer comfortable working around gas appliances. However, diagnosing and replacing components like the radiant sensor, gas valve coils, or igniter requires familiarity with gas dryer systems and basic electrical testing. Because this fault involves a gas burner circuit, many homeowners choose to have a qualified technician perform the repair to ensure safety and correct diagnosis.

Repair costs depend on which component has failed. Parts such as a radiant sensor or igniter are relatively inexpensive, typically in the range of $10 to $50 each, while gas valve coil kits can run $30 to $80. Labor costs for a stack dryer can be higher than a standard dryer due to the additional disassembly required to access the lower pocket, so total repair costs commonly range from $100 to $350 depending on the fault and your location.
