What F2E3 means on a Maytag dryer

The F2E3 error code on a Maytag dryer indicates a model ID parameter mismatch between the User Interface (UI) control board and the Appliance Control Unit (ACU). These two components communicate with each other during startup and operation, exchanging identification data to confirm they are compatible. When the model ID stored in one component does not match the ID expected by the other, the dryer flags this conflict as F2E3 and halts normal operation to prevent unpredictable behavior.

This error is almost exclusively triggered by a parts substitution event. If either the UI board or the ACU was replaced during a previous repair, and the replacement part carried a different part number than the original, the mismatch will surface as F2E3. This can happen when a technician installs a visually similar but functionally incompatible control board, or when an incorrect part is shipped and installed without cross-referencing the model-specific part number. The dryer itself has no way to resolve this conflict through software alone because the incompatibility is embedded in the hardware identity of the components.

Resolving F2E3 requires identifying which component has the incorrect part number. Both the UI and ACU will have part numbers printed on labels affixed to the boards. These numbers must be cross-referenced against the part numbers specified for the dryer's exact model number. The mismatched board must then be replaced with the correct, model-specific component. Simply resetting the control or cycling power will not clear this fault.

Common causes of F2E3

  1. 01

    Wrong replacement ACU installed

    Part replacement

    If the Appliance Control Unit was recently replaced, it may have been sourced with an incorrect part number that does not match the dryer's model. Cross-reference the part number on the ACU board label against the model's specified part to confirm.

  2. 02

    Wrong replacement UI board installed

    Part replacement

    A User Interface board swapped in during a prior repair may look identical to the correct part but carry a different model ID internally. Verify the part number printed on the UI board matches the model-specific requirement.

  3. 03

    Incorrect part shipped by supplier

    Part replacement

    Suppliers occasionally ship a substitute or cross-referenced part that is not a true match for the specific model. Even if the board was ordered by model number, confirm the received part number against the dryer's documented specification.

  4. 04

    ACU or UI replaced with a used part from a different model

    Part replacement

    Used or salvage control boards sourced from a different but similar Maytag dryer model may not carry the correct model ID, triggering the F2E3 mismatch. Used parts should always be verified by exact part number before installation.

Frequently asked questions about F2E3

What does F2E3 mean on a Maytag dryer?
F2E3 means the dryer has detected a model ID mismatch between the User Interface board and the Appliance Control Unit. These two control components exchange identification data on startup, and if the IDs do not match, the dryer triggers this fault and stops operating. This conflict is almost always the result of one of these boards being replaced with an incorrect part number. Normal operation cannot resume until the mismatched component is replaced with the correct model-specific part.
Will resetting my Maytag dryer clear the F2E3 error?
No, resetting the dryer by cycling power or pressing a reset sequence will not clear F2E3. The mismatch is based on the hardware identity stored in the control boards themselves, not a temporary software glitch. The fault will return every time the dryer powers on until the incorrectly matched component is replaced with the proper part number.
How do I fix the F2E3 error on my Maytag dryer?
Start by locating the part number labels on both the User Interface board and the Appliance Control Unit. Cross-reference each part number against the correct specification for your dryer's exact model number. Whichever board does not match needs to be replaced with the correct model-specific component. If a repair was recently performed, the most likely culprit is whichever board was installed during that service.
Is it safe to keep using my dryer with an F2E3 error?
The dryer is designed to halt operation when F2E3 is active, so continued use in a normal sense is prevented. However, you should not attempt to bypass the fault or force the machine to run with mismatched control boards, as the two components may not coordinate heating and motor functions correctly. Address the parts mismatch before returning the dryer to service.
How much does it cost to repair an F2E3 error on a Maytag dryer?
The cost depends on which board requires replacement. A User Interface board typically ranges from $75 to $200 for the part alone, while an Appliance Control Unit can range from $100 to $300 or more depending on the model. If a technician is performing the repair, add labor costs on top of the part price. In many cases, if a recent repair caused the mismatch, the supplier or technician responsible may be able to exchange the incorrect part at reduced or no additional cost.
