What the F4E4 error code actually means

Your Maytag dryer is not receiving enough electrical power from one of the two circuits it needs to run. Electric dryers require two separate 120-volt power lines working together to create the 240 volts needed for heating, and your dryer is detecting that one of those lines is missing or extremely weak. This is typically a problem with your home's electrical supply, outlet, or wiring rather than the dryer itself.

Questions people ask about F4E4

What does error code F4E4 mean on a Maytag dryer?
F4E4 means the Central Control Unit has detected low voltage on the L2 leg of the 240V supply, reading below 50 volts. Electric dryers need both L1 and L2 legs at roughly 120V each to operate correctly. On gas models, this code can also indicate a problem with the P14 harness loopback at the CCU rather than an actual power supply issue.
Can I still use my Maytag dryer when F4E4 is active?
Operating the dryer with F4E4 active is not recommended. The error indicates insufficient voltage on L2, which means the heating element may not function, leaving clothes damp, and continued operation under abnormal voltage conditions can stress components. Running the machine also will not clear the underlying cause and may complicate diagnosis.
How much does it cost to fix F4E4 on a Maytag dryer?
If the fix is a tripped breaker or a loose power cord, the cost is zero. A replacement household fuse for the dryer circuit is typically under five dollars. If the P14 harness on a gas model needs repair or replacement, parts are generally inexpensive. A CCU replacement is the most costly outcome, with boards commonly ranging from $100 to $250 in parts, plus labor if you hire a technician. Exhaust all power supply and connection checks before pursuing board replacement.
How do I fix F4E4 on a Maytag dryer?
Start at your home's electrical panel and check whether a circuit breaker has tripped or a fuse has blown, specifically on the L2 leg of the dryer circuit. Reset the breaker or replace the fuse, then confirm the dryer's power cord is fully seated at the outlet and tightly connected at the terminal block. If the code persists, inspect the relay connections on the CCU and, on gas models, verify the P14 connector loopback on pins 4 and 5 is intact. If all external checks pass, the CCU may need replacement.
Why is my Maytag dryer running but not heating and showing F4E4?
This symptom is a classic sign that L2 voltage is missing or very low. The dryer motor and control board run on L1 alone, so the drum can spin and the display can function, but the heating element requires the full 240V across both legs. Check your breaker panel immediately for a partially tripped double-pole breaker, which can leave one leg dead while the other stays live.
