What Does Error F31 Mean?
The Whirlpool dryer error F31 indicates a low or no L2 line voltage condition detected by the dryer’s diagnostics. This malfunction often prevents the dryer from heating or starting and may be accompanied by unusual beeping sounds. The primary cause is typically a lack of adequate voltage supply, but it may also stem from loose connections or tripped breakers.
Common Symptoms:
- Dryer displays F31 code on the control panel
- Dryer may not heat
- Dryer may not start or may shut down during a cycle
Possible Causes
- Low or no L2 line voltage supply to the dryer (high)
- Loose or faulty power cord connection at the dryer’s terminal block (medium)
- Tripped or failed double‑pole circuit breaker (medium)
How to Fix Error F31
DIY Fix Check power supply and breakers
- Ensure the dryer is receiving power and is plugged into a 240 V outlet.
- Check that both poles of the double‑pole circuit breaker for the dryer are fully on and not tripped.
- If a breaker is tripped, reset it and attempt a dry cycle.
DIY Fix Inspect and tighten power cord connections
- Turn off and unplug the dryer or switch off the breaker feeding it.
- Remove the rear access panel to inspect the power cord connections at the terminal block.
- Look for loose screws or signs of burning or melting; tighten any loose connections.
Technician Only Test outlet voltage and replace damaged components
- Test the dryer outlet with a multimeter to confirm proper 240 V between hot legs and correct leg‑to‑neutral voltage.
- Inspect and replace any damaged terminal block or power cord.
- After correcting voltage issues, perform a controlled test run.
Parts needed: Multimeter, Replacement terminal block, Replacement power cord
- If you are not comfortable working with high‑voltage electrical components
- If testing shows correct power supply but code persists
- If visible damage (burnt components) is found at the terminal block
