Maytag Dryer Error Code 24

Code 24 means the control board detected an invalid or unrecognized signal from the rotary switch, which is the cycle selector switch behind your control knob. The board expects a specific electrical signal for each knob position, and when the signal it receives does not match any valid position, it sets code 24. The dryer will typically stop operating until the issue is resolved.

No. Code 24 means the dryer cannot confirm which cycle you have selected, so the control board will not allow normal operation. Running the dryer in this state risks undefined behavior since the machine does not know which heat level or timing to apply. Address the rotary switch fault before using the dryer again.

Unplugging the dryer for a few minutes will clear the code from the display, but code 24 will return as soon as the control board reads the rotary switch again and still receives an invalid signal. A power reset alone does not fix the underlying fault with the switch or its wiring. Use the reset only to confirm whether the code is intermittent while you are actively diagnosing the problem.

Start by unplugging the dryer and visually inspecting the wiring harness connectors at the rotary switch and at the control board for loose pins or damaged wires. Reseat any loose connectors and check whether the knob and shaft are properly aligned and not forced between positions. If the wiring looks intact, test the rotary switch with a multimeter across each contact position to verify it produces the correct resistance at every detent. A switch that fails this test needs to be replaced with the correct Maytag part for your model.

If the fix is a loose wiring harness connection, the cost is just your time. A replacement rotary switch for a Maytag dryer typically costs between $15 and $50 for the part depending on the model. If a technician is needed for diagnosis and installation, expect a service call fee plus labor, which commonly puts the total repair in the $100 to $200 range. A control board replacement is significantly more expensive, often $150 to $300 for the part alone, but this is rarely the cause.
