Maytag Dryer Error Code F4E1

F4E1 means the CCU detected no voltage at the heater relay during Diagnostic Test Mode. The control board ran a self-check on the heater relay circuit and found that voltage was not present where it expected to be. This points to a problem in the wiring or relay that controls power to the heating element.

F4E1 only appears in Diagnostic Test Mode, so the dryer may still run a normal cycle, but it likely will not heat properly or at all. Running the dryer without functioning heat is not dangerous, but your clothes will not dry. You should address the fault before relying on the dryer for normal use, since the underlying wiring or relay issue could worsen over time.

Not necessarily. The most common cause of F4E1 is a loose wire connector at the heater element or heater relay on the CCU, which costs nothing to fix. CCU replacement is only needed if the heater relay itself has failed internally. Work through the wiring checks first, and only consider replacing the CCU if all connections are confirmed solid and F4E1 persists.

Start by unplugging the dryer, then check that all wire connectors are fully seated at the heater element and at the heater relay terminals on the CCU. Push each connector firmly until it clicks or seats flush. Restore power and run the diagnostic again. If F4E1 returns, inspect the wiring harness between the CCU and the heater element for damaged or broken wires. If the wiring is intact, the CCU likely has a failed heater relay and will need to be replaced.

If the fix is simply reseating a loose wire connector, there is no parts cost and it takes only a few minutes. If the wiring harness is damaged, a replacement harness typically costs between $20 and $60 in parts. If the CCU needs to be replaced, parts alone generally run $100 to $250 depending on the model, with professional labor adding another $100 to $200. Checking and reseating connections yourself before calling a technician can save significant money.
