Maytag Dryer Error Code F1E3

F1E3 indicates that the Appliance Control Unit (ACU) and/or the User Interface board installed in the dryer does not match the dryer's model. This is a controller mismatch error that applies only to electric dryer models. The dryer detects the part number discrepancy during operation and displays this code to flag the incompatibility.

To fix F1E3, locate the model number of your dryer (found on the label inside the door opening) and verify that the part numbers on both the ACU and the User Interface board are correct for that model. Any board with an incorrect part number must be replaced with the properly matched component. If you are unsure which board is the source of the mismatch, both should be verified before purchasing parts.

The cost depends on which component requires replacement. A replacement ACU or User Interface board for a Maytag dryer typically ranges from $80 to $250 or more per board, depending on the specific model. If professional installation is needed, labor costs will add to that total. Confirming the exact part numbers before purchasing is critical to avoid repeating the same mismatch error.

No, resetting the dryer will not clear the F1E3 code. Because the error is caused by a hardware mismatch between installed control boards and the dryer model, the fault will return immediately after any reset. The only way to resolve it is to install the correct ACU and/or UI board with matching part numbers.

A dryer displaying F1E3 has a controller mismatch that means it is not operating with the correct control configuration for its model. Running the dryer in this state is not recommended, as the mismatched controller may not properly regulate heating cycles or safety shutoffs. The error should be resolved before regular use continues.
