Maytag Dryer Error Code F31 — L2 Line Voltage Low
What this means
The F31 error code indicates the dryer control board is sensing low or no voltage on the second leg (L2) of the 240-volt power supply. Electric dryers require a full 240-volt supply from two circuit breakers. If one breaker trips or a connection is loose, the dryer motor may run but the heating element will not energize, resulting in clothes that do not dry.
Alternate codes: F-31
Step-by-step fix
4 stepsCheck the circuit breakers
Go to your electrical panel and check the two breakers serving the dryer circuit. If one is tripped, reset it by switching it fully off, then back on.
Both breakers for the dryer circuit should be in the ON position — they are usually paired together.
Test the outlet voltage
Use a multimeter set to AC voltage to test the dryer outlet. You should read approximately 240 volts between the two hot terminals.
If you read only 120 volts, one leg of power is missing — the breaker or wiring is faulty.
Inspect the power cord
Unplug the dryer and examine the power cord for damage, burn marks, or loose prongs. Check that the terminal connections inside the dryer junction box are tight.
A loose terminal connection can cause intermittent voltage drops.
Contact an electrician
If the outlet voltage is consistently below 240 volts or one breaker keeps tripping, there is an electrical issue in your home wiring that requires a licensed electrician.
Do not continue using the dryer with low voltage — it can damage the control board.
When to call a professional
This error involves your home's electrical supply. If resetting breakers does not resolve the issue, contact a licensed electrician to diagnose the wiring problem.
