Whirlpool Dryer Error Code F4 E4 — Power Supply Issue (No 240V)
What this means
The F4 E4 error code on Whirlpool electric dryers indicates the dryer is only receiving 120V instead of the required 240V. Electric dryers need two 120V legs from the home's electrical panel to create 240V for the heating element. If one leg is lost (due to a tripped breaker, blown fuse, or loose connection), the dryer motor may run but the heating element will not work. This error is functionally the same as the L2 code on some models.
Alternate codes: F4E4
Step-by-step fix
4 stepsCheck the circuit breaker
Go to your home's electrical panel and find the double-pole breaker for the dryer. Even if both halves appear to be in the ON position, flip both to OFF and then firmly back to ON. A breaker can trip internally while still appearing engaged.
Dryer breakers are typically 30-amp double-pole breakers. If one half has tripped, it may not be visually obvious.
Test the dryer outlet voltage
Use a multimeter set to AC voltage. Test between the two hot slots on the dryer outlet — you should read approximately 240V. Test between each hot slot and the neutral — each should read approximately 120V.
If you read 120V between the hot slots instead of 240V, one leg of the circuit has been lost at the breaker or the wiring.
Inspect the power cord connection
Unplug the dryer and remove the access panel on the back to expose the power cord terminal block. Check that all wires are firmly connected to the terminal block and that no terminals are burned or corroded.
Loose terminal connections are a common cause of this error and can create a fire hazard — tighten all connections securely.
Contact an electrician if needed
If the breaker is not tripped and the outlet reads the correct voltage, but the error persists, there may be an intermittent wiring issue in the home's electrical system. An electrician should inspect the circuit.
Corroded or aluminum wiring connections in older homes can cause intermittent voltage drops under the heavy load of a dryer.
When to call a professional
If you are not comfortable testing electrical circuits with a multimeter, or if you identify a wiring issue in the wall circuit, contact a licensed electrician. This is not an appliance repair issue but a home electrical issue.
