Maytag Dryer Error Code D23

D23 is a Burner Return Voltage Fault. It means the control board detected an active voltage signal on the burner return line while the heat relay contacts were supposed to be open and the burner should have been off. Because this represents a contradiction in the heating circuit, the control immediately shuts down and opens the interposing relay as a protective measure.

No. The D23 fault is a safety-triggered shutdown related to the gas burner circuit. The dryer should not be used again until the fault has been diagnosed and the root cause corrected. Continuing to operate the dryer without resolving the fault could pose a risk of uncontrolled burner activation.

Repair costs vary depending on the failed component. Wiring repairs or connector replacements are typically the least expensive option. Relay replacement parts generally range from around $15 to $60 depending on the specific component. A control board replacement is the most costly possibility, with parts typically ranging from $100 to $250 or more, plus labor if a technician is involved.

Some causes of D23, such as a loose wiring connector or a visibly damaged harness, are within reach of a knowledgeable DIYer. However, because this fault involves the gas burner circuit and relay components, and because it is a safety-triggered shutdown, it is strongly recommended to have a qualified appliance technician inspect and repair the dryer. Working on gas appliance components without proper training carries real risk.

A power reset may temporarily clear the fault code and allow the dryer to restart, but if the underlying problem with the heat relay, wiring, or control board has not been fixed, the D23 code will return. Resetting the dryer without repairing the root cause is not a solution and should not be relied upon as a fix.
