Amana Dryer Error Code F:31

The F:31 code on an Amana dryer means the electronic control detected a low voltage condition, specifically a supply voltage below 30 volts. This code only appears during Diagnostic Test Mode, not during normal operation. It points to a problem with the power supply reaching the dryer, such as a tripped breaker, blown fuse, or a loose power cord connection.

It is not advisable to continue using the dryer until the underlying power issue is resolved. A low voltage condition can cause the dryer to operate incorrectly, overheat certain components, or fail to function safely. The F:31 code only appears in Diagnostic Test Mode, so have the power supply inspected and corrected before returning the dryer to regular use.

The cost depends on the cause of the fault. If only a tripped breaker needs to be reset or a household fuse replaced, the cost is minimal, typically a few dollars for a fuse. If the power cord needs replacement or reseating, parts and labor can range from around $20 to $80. A control board replacement, if required, can range from $150 to $350 or more depending on parts and labor costs in your area.

Start by checking your home's electrical panel for a tripped circuit breaker or blown fuse and restore power if needed. Next, confirm the dryer's power cord is fully plugged into the outlet and that the cord terminals are securely connected at the dryer's terminal block. If power supply checks out, inspect the relay connections on the electronic control board for corrosion or looseness. If those steps do not resolve the issue, the control board itself may need to be replaced.

Simply resetting the dryer by unplugging it and plugging it back in will not permanently clear the F:31 code if the root cause has not been corrected. The code will return the next time Diagnostic Test Mode is run if the voltage condition is still present. The underlying electrical issue must be identified and fixed first.
