What this codemay mean.
A plain-language reading of the code — always confirm against your model’s documentation.
Mean
F4E4 (Low or No Line Voltage) indicates a possible home power supply problem that keeps the dryer's heater from turning on.
F4E4 is a Low or No Line Voltage diagnostic code. It indicates a possible problem with your home power supply that keeps the dryer’s heater from turning on. Touch any pad to clear it and return to the estimated time remaining.
Check these in order
Breakers and fuses. An electric dryer uses two household fuses or breakers. Replace a blown fuse or reset a tripped breaker.
Power cord. Confirm it is installed properly, using the Installation Instructions. Terminal screws at the dryer should be tight, and the dryer must be unplugged before you check them.
Heated cycle. Pick a Timed Dry heated cycle and restart the dryer.
Some background from the manual: electric dryers require a separate 30-amp circuit fused on both sides of the line, so two breakers operate the dryer. One circuit runs the motor that turns the drum and the other runs the heating element. A tripped breaker on either side may stop the dryer heating. Electric dryers also need a 240-volt supply, and if you do not have it you should check with a qualified electrician.
If the message persists, consult a qualified electrician.
Laundry towers
The tower entry reads Main Heater as the potential cause. Reset by cutting power for one minute (dryer) or 5 minutes (washer), then schedule service if the code comes back.
Related codes
F4E1 concerns the heater or heater relays, F4E3 restricted air flow, and F4E2 the main heater.
