Kenmore Dryer F:31 error code

The dryer's electronic control measured the L2 leg of its 240-volt supply at under 30 volts. In plain terms, the dryer is only receiving about half its normal power, so it cannot heat or tumble correctly and stops with this code.

Also shown as: F31, F-31

Quick answer: Kenmore dryer error code F:31: dryer receiving only half its 240V power. The most common cause is tripped or half-tripped house circuit breaker. Try this first — reset both breaker switches. If that does not clear it, inspect the power cord and terminal block.

What causes the F:31 error?

  • Tripped or half-tripped house circuit breaker
  • Loose or corroded wire on the dryer terminal block
  • Damaged power cord
  • Faulty 240V outlet or house wiring problem

How to fix Kenmore F:31 — step by step

Work through these in order, from simplest and safest first. Stop as soon as the code clears.

  1. Reset both breaker switches
    Find the dryer's double breaker in your home panel, flip it fully off, then back on. A 240V breaker can look on while one leg is still tripped.
  2. Inspect the power cord and terminal block
    Unplug the dryer and remove the small cover where the cord connects. Tighten any loose wire connections and replace the cord if it looks damaged or discolored.
    Safety warning: The terminal block carries 240 volts — always unplug the dryer before opening the cover.
  3. Have an electrician check the supply
    If the breaker, cord, and connections are fine, an electrician should measure the outlet voltage. The dryer needs roughly 208–240 volts across both legs.
    Safety warning: House wiring repairs should be left to a licensed electrician.

When to call a technician

Stop and call a qualified technician if any of these apply:
  • Voltage at the outlet is low even after resetting the breaker
  • Wires look burned or melted at the terminal block

Frequently asked questions

Can I run the dryer on 120V temporarily?

No — an electric Kenmore dryer needs the full 240V supply to heat and tumble safely. Running on partial power can damage the motor and electronics.
