Whirlpool Dryer Error Code FP E3

FP E3 is a Card Reader Communication Error, meaning the dryer's main control board has lost the data signal it expects from the card reader module. The fault is detected at the AA3 connector on the control board. This code can appear due to a loose connector, damaged wiring, or a failed card reader.

The dryer may suspend operation when this fault is active, depending on how the control system handles the communication loss. It is best to resolve the error before continuing to use the appliance to avoid potential secondary damage from operating with an unresolved control fault.

The FP E3 fault relates to a communication error between the card reader and the control board and is not directly associated with a heating, venting, or fire hazard. However, any unresolved control board fault should be diagnosed promptly to ensure the appliance is operating as intended.

Cycling power is the recommended first step and may clear the error if the communication loss was a temporary glitch. If the code returns after the power cycle, there is an underlying wiring or hardware problem that requires inspection and repair before the error will stay cleared.

If the fix is simply reseating a loose connector, there may be no parts cost and minimal labor time. If the card reader module needs replacement, parts and labor combined can range from roughly $75 to $250 or more depending on the specific model and local labor rates. Replacing the main control board, if that is found to be the cause, will typically cost more.
