What 13 means on a Maytag dryer
Error code 13 on a Maytag dryer indicates an Upper Dryer Door Circuit Failure, specifically related to the steamer circuit. The control board monitors the signal from the upper dryer door switch or the steamer circuit continuously, and when that signal drops low for more than one second, the board registers this fault and halts normal operation. This type of fault is an open or interrupted circuit condition, meaning the electrical signal is not completing its path back to the control board as expected.
The steamer circuit in these Maytag dryer models includes wiring harnesses, connectors, and terminal connections that link the upper door assembly to the main control. Loose or open wire terminals are the leading cause of this fault. Over time, vibration during dryer operation can cause connector pins to back out of their housings or terminal crimps to loosen, breaking continuity in the circuit. A visual and physical inspection of all wire terminals in the steamer circuit path is the correct first diagnostic step.
If loose or open terminals are not found during the initial inspection, the fault may point to a damaged wiring harness with a broken conductor, a failed door switch in the upper door assembly, or a defective control board that is misreading the signal. Technicians should check for any visible wire chafing or pinched sections along the harness routing, and verify connector seating at each end of the circuit before condemning any individual component.

Common causes of 13
- 01
Loose or disconnected wire terminals
Wiring / connectionVibration from normal dryer use can cause wire terminals in the steamer circuit to loosen or back out of their connectors. Inspect all connector housings in the steamer and upper door circuit for pins that are not fully seated or that pull out with light resistance.
- 02
Open or broken wiring harness
Part replacementA conductor inside the wiring harness may be broken internally or chafed against a sharp edge, causing an open circuit. Look for pinched, frayed, or burned sections along the harness routing from the upper door to the control board.
- 03
Failed upper door switch
Part replacementThe upper dryer door switch sends the signal monitored by the control board, and if the switch has failed internally it will produce a low signal regardless of door position. Testing continuity across the switch contacts with a multimeter will confirm whether the switch has opened and needs replacement.
- 04
Corroded or damaged connector pins
Part replacementMoisture or heat exposure can cause corrosion on the terminal pins inside connectors, increasing resistance and eventually breaking the circuit signal. Look for green or white oxidation on pin surfaces and clean or replace affected connectors as needed.
- 05
Defective main control board
Part replacementIf all wiring, terminals, and the door switch test correctly, the control board itself may be misinterpreting or failing to read the circuit signal. This is the least common cause and should only be considered after the rest of the circuit has been ruled out.
