The Maytag dryer error code F20 indicates a potential issue with the door switch or control board, often causing the dryer to fail to start or to stop unexpectedly during a cycle. Additionally, it may be related to heating circuit or heater relay problems, leading to inadequate heating or shut-offs soon after starting. If the F20 error persists even after a power cycle reset, further investigation into the heating components may be necessary.

  • Error persists after reset/power cycle.

Possible Causes

  • Faulty heater relay or other heating circuit component (medium)

How to Fix Error F20

DIY Fix Power cycle the dryer

  1. Turn off the dryer at the circuit breaker or unplug it.
  2. Wait at least 5 minutes.
  3. Restore power and run a timed dry cycle to see if F20 reappears.

DIY Fix Basic heat circuit observation

  1. Check if the dryer heats when running a cycle despite the F20 code.
  2. Listen for unusual sounds or lack of heating, which may suggest heating circuit issues.

Technician Only Inspect and test heating circuit components

  1. Disconnect power.
  2. Access the dryer’s heating element housing or burner assembly depending on model.
  3. Visually inspect wiring for heat damage, loose connections, and test thermostats/thermal cutoffs for continuity.
  4. Test heating element resistance and inspect heater relay on the control board.
  5. Replace any failed components such as thermostats, thermal cutoffs, heating element, or heater relay.

Parts needed: Heating element assembly, High-limit thermostat, Thermal cutoff, Heater relay or control board section

🛑 When to Call a Pro:
  • If the error persists after a power reset and basic checks.
  • If heating is absent or intermittent and internal component testing exceeds user comfort or expertise.
  • If visible damage or burned wiring is observed.
