What 24 means on a Maytag dryer

Error code 24 on a Maytag dryer indicates the control board has detected an incorrect position signal from the rotary switch. The rotary switch communicates cycle selection to the control board by sending a specific electrical signal corresponding to the selected position. When the board reads a signal that does not match any valid position in its programming, it throws code 24 and typically halts operation to prevent running an undefined or unintended cycle.

For a homeowner, think of the rotary switch as the cycle selector knob on your dryer. Inside that knob assembly is a switch with electrical contacts that tell the dryer's computer which setting you have chosen. When the dryer shows code 24, the computer received a position signal it does not recognize. This can happen because the switch itself has failed, the wiring connecting it to the control board is damaged or loose, or in less common cases, the control board itself has failed and is misreading a valid signal.

This code is specific to the rotary switch circuit and is not triggered by thermal or motor faults. Diagnosing it generally involves checking the wiring harness connections at the switch and control board, then testing the switch contacts for proper resistance values at each position.

Common causes of 24

  1. 01

    Failed rotary switch

    Part replacement

    The internal contacts of the rotary switch wear out or corrode over time, causing it to output a signal that falls outside the valid range the control board expects. This is the most frequent root cause of code 24.

  2. 02

    Loose or damaged wiring harness to the rotary switch

    Wiring / connection

    A connector that has worked loose or a wire with a break or chafe point between the rotary switch and the control board can produce an intermittent or incorrect signal. The board sees an invalid voltage and triggers the code.

  3. 03

    Rotary switch knob or shaft misalignment

    Wiring / connection

    If the knob has been forced past a stop position or the shaft is bent, the switch mechanism may rest between detents and transmit an undefined position signal to the control board.

  4. 04

    Faulty control board

    Part replacement

    If the rotary switch and its wiring test correctly, the control board may be misreading a valid switch signal due to a failed input circuit. This is the least likely cause but should be considered after all other components check out.

Frequently asked questions about 24

What does error code 24 mean on a Maytag dryer?
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.
How do I fix error code 24 on a Maytag dryer?
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.
Is it safe to use my Maytag dryer when code 24 is showing?
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.
How much does it cost to fix a Maytag dryer with error code 24?
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.
Can I reset error code 24 on my Maytag dryer by unplugging it?
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.
