Whirlpool Dryer L2 error code
L2 means the dryer is not getting proper voltage on the L2 power leg. An electric dryer needs full 240 volts to heat — with L2 missing or low, it will tumble but never get hot.
Also shown as: L2, F4E4, F31

What causes the L2 error?
- Tripped or half-tripped double-pole circuit breaker
- Loose or burnt connection at the dryer terminal block
- Damaged power cord or wall outlet
- Utility power issue or a failing breaker
- Dryer wired incorrectly after installation or a move
How to fix Whirlpool L2 — step by step
Work through these in order, from simplest and safest first. Stop as soon as the code clears.
- Reset the breaker fully
Go to your electrical panel and switch the dryer breaker fully OFF, then fully ON. A 240V breaker can look on while one leg has tripped, so push it all the way off first.Safety warning: If the breaker is hot, buzzing, or smells burnt, leave it off and call an electrician. - Check the terminal block (advanced)
With the breaker OFF, remove the dryer's terminal block cover and look for loose, burnt, or melted wires. Tighten any loose terminal screws. Burnt wires or a melted block need professional repair.Safety warning: Verify power is truly off with a non-contact tester before touching the terminal block. 240V can kill. - Test the outlet voltage (advanced)
With a multimeter, check for about 240 volts between the two hot slots of the dryer outlet, and 120 volts from each hot to neutral. Low or missing voltage on one leg confirms a supply problem, not a dryer problem.Safety warning: Only test a live outlet if you know how to use a multimeter safely. When in doubt, call an electrician.
When to call a technician
- L2 persists after resetting the breaker
- The terminal block or cord shows burning or melting
- You are not comfortable testing a live 240V outlet
- The breaker trips repeatedly or feels hot
Frequently asked questions
My dryer runs but has no heat and shows L2. Is the dryer broken?
Usually not — the dryer is fine, but it is only getting 120V instead of 240V. The heater cannot work on half voltage. Fix the power supply and heat returns.
Can a loose power cord cause L2?
Yes. A loose terminal screw at the dryer's terminal block is one of the most common causes, and it can arc and melt the block over time — so check it promptly.
The breaker looks fine. What next?
The breaker can fail internally while looking normal. An electrician can test voltage at the breaker and the outlet to find the dead leg.
