Maytag Dryer Error Code F:31

F:31 indicates that the electronic control detected a low voltage condition, specifically below 30 volts, during Diagnostic Test Mode. It points to a problem with the incoming electrical supply or the connections delivering power to the control board. This code only appears when a technician runs the dryer's built-in diagnostic test, not during regular operation. The first areas to check are the household circuit breakers, the power cord, and the relay connections on the control board.

F:31 only surfaces during Diagnostic Test Mode, so your dryer may still operate for normal cycles if the voltage issue is intermittent or minor. However, running an appliance on an inadequate or unstable power supply can cause damage to the electronic control board and other components over time. It is advisable to diagnose and correct the power supply problem before continuing regular use.

If the fix is simply resetting a tripped breaker or reseating a loose power cord, there is no parts cost involved. Replacing a wall outlet or having an electrician service the circuit can range from around 100 dollars to 250 dollars or more depending on local labor rates. If the electronic control board needs replacement, parts and labor combined typically range from 200 dollars to 400 dollars or higher depending on the specific model and service provider.

Simply resetting or unplugging the dryer will not permanently resolve F:31 if the underlying power issue remains. Because this code only appears in Diagnostic Test Mode, it will return each time diagnostics are run until the root cause is corrected. Addressing the actual voltage problem, such as resetting a tripped breaker or securing a loose power cord connection, is what clears the condition.

Start by checking your home's breaker panel to confirm the dryer's double-pole circuit breaker has not tripped and reset it if needed. Next, verify the power cord is fully plugged into the outlet and that the terminal connections at the dryer are tight and secure. If household power checks out, inspect the relay connections on the electronic control board for looseness or corrosion. If all connections are sound and the fault persists, the wall outlet wiring or the control board may require further evaluation.
