What Does Error F31 Mean?

The Kenmore Dryer F31 error code indicates a low voltage issue, specifically low L2 voltage detected on the 240V supply circuit, often below 30V. This malfunction can cause the dryer to not start, fail to heat, or produce unusual clicking sounds. The problem typically stems from electrical supply issues or a faulty motor control board, which may require inspection of power supply connections and the breaker panel.

Common Symptoms:

  • Dryer may not heat
  • Dryer may not start or may shut down unexpectedly
  • Display of F31 error code on control panel

Possible Causes

  • Low or missing L2 leg voltage in the 240 V power supply (high)
  • Loose, damaged, or burned power cord and terminal connections (medium)

How to Fix Error F31

DIY Fix Check house power supply and breakers

  1. Ensure dryer is turned off and unplugged if accessing electrical components
  2. Check the home breaker panel for the dryer circuit and reset any tripped double‑pole breaker
  3. Verify both sides of the 240 V breaker are supplying power and not partially tripped

Technician Only Verify and repair power supply connections

  1. Disconnect power to the dryer at the breaker and unplug
  2. Inspect dryer power cord for damage and correct type
  3. Remove access panel and inspect terminal block connections for burn marks, looseness, or damage
  4. Test incoming voltage with a multimeter at the terminal block to confirm ~240 V between hot legs
  5. Repair or replace power cord or terminal block as needed
  6. If incoming supply has correct voltage and connections are sound but F31 persists, inspect control board sensing circuit

Parts needed: Dryer power cord, Terminal block assembly, Multimeter for testing

🛑 When to Call a Pro:
  • If unfamiliar with high‑voltage electrical work
  • If voltage tests show incorrect supply issues requiring electrician intervention
  • If error persists after verifying supply and connections
