Possible Causes
Missing L2 leg of 240V supply, tripped double-pole breaker, burned power cord terminal block, loose wiring at terminal block
How to Fix / Troubleshooting
Safety First: Turn off the dryer breaker and verify power is off before opening the terminal block cover. 240V can be lethal.
Steps:
- Check breaker: At the electrical panel, firmly switch the dryer double-pole breaker OFF then ON to reset. A partially tripped breaker can remove one leg of power.
- Test outlet voltage: Using a multimeter, verify 240 VAC between the two hot slots and 120 VAC from each hot to neutral/ground at the dryer receptacle.
- Inspect terminal block: Remove the rear cover over the power cord connection. Look for burned wires, melted plastic, or loose screws. Tighten connections and replace any damaged parts.
- Check power cord: If the cord shows signs of overheating or damage, replace it with the correct 3- or 4-wire dryer cord.
- Control board: If supply voltage is correct and wiring is sound, F31 may indicate a control board sensing issue requiring replacement.
