What the 31 error code actually means

Your Maytag dryer's control board could not recognize what model it is when it started up, so it switched to a basic backup mode to keep running. This is usually caused by a communication problem between the control board and the small memory chip that stores your dryer's specific settings. The dryer may still operate in a limited way, but it needs to be diagnosed to restore full, correct functionality.

Questions people ask about 31

What does error code 31 mean on a Maytag dryer?
Error code 31 means the control board could not identify the dryer's model ID during startup and fell back to a default configuration. This is a memory or communication issue involving the EEPROM where model-specific data is stored. The dryer may continue to operate, but it is running on generic settings rather than the calibrated values for your specific model.
Can I still use my Maytag dryer with error code 31 active?
The dryer may run with code 31 active because it defaults to a fallback configuration rather than shutting down completely. However, using it long-term on default settings can result in improper cycle timing, incorrect heat levels, or inaccurate moisture sensor behavior. It is best to resolve the underlying cause before relying on the dryer for regular use.
Will unplugging my Maytag dryer fix the 31 error code?
Unplugging the dryer for several minutes performs a hard reset and can clear error 31 if the cause was a transient power interruption or software glitch during startup. If the code returns after the reset, the EEPROM or main control board has a hardware problem that a power cycle will not resolve and a part replacement will be needed.
How do I fix error code 31 on a Maytag dryer?
Start by unplugging the dryer for at least 5 minutes, then restore power and check whether the code clears. This can resolve transient software glitches. If code 31 returns on every startup, the control board's EEPROM is likely corrupted or the control board itself is failing and will need to be replaced. A technician can confirm which component is at fault before ordering parts.
How much does it cost to fix error code 31 on a Maytag dryer?
If a hard reset clears the code, the fix costs nothing. If the main control board needs to be replaced, parts typically range from $100 to $250 depending on the specific Maytag model, plus $75 to $150 in labor if you hire a technician. A DIY replacement is feasible for someone comfortable with appliance repair, as the control board is usually accessible after removing the back or top panel.
