Whirlpool Dryer L2 — What It Means & How to Fix It
Also shown as F31 on some models.
L2 on a Whirlpool dryer means the 240-volt supply is weak or a leg is missing — the dryer spins but won't heat. Check the breaker handles, then call an electrician.
What this code means
L2 is Whirlpool's low-line-voltage code: the dryer needs two 240-volt legs to run its heater, and the control detected that one leg is missing, weak, or sagging under load. The classic signature is a dryer that tumbles fine but never heats — the motor runs on the leg that works while the heater starves on the leg that doesn't. Fixed wiring, the outlet, the cord, or the breaker causes it; testing and repairing live 240-volt supply is a licensed electrician's job.
L2 is the low-line-voltage code on Whirlpool-family dryers, shown on the display when the supply is sensed below spec. If the same dryer heats intermittently, suspect a loose connection somewhere in the line, not an intermittent dryer fault. The model number is on the door frame.
Most likely causes
| Cause | How likely | DIY-fixable? |
|---|---|---|
| One leg of the 240V supply missing at the outlet | Common | No — electrician job |
| Half-tripped double breaker | Common | Partly — check both handles |
| Loose or burned cord connection | Occasional | No — electrician job |
| Utility voltage sag under load | Less common | No — electrician job |
What you can try yourself
- Check the dryer breaker: a double breaker has two handles and both must be on — a half-tripped one drops a leg.
- Confirm the dryer is plugged fully into its outlet and that the cord isn't damaged or pinched.
- If the breaker handles are both on and the plug is seated, stop — the next steps (outlet, cord terminals, neutral) are live-panel mains work.
- An electrician will verify both legs under load at the outlet and the dryer connection, then re-terminate the loose or burned point.
When to call a technician
- The entire L2 path is a stop sign for DIY — it names the mains supply to a 240-volt appliance.
- The dryer tumbles but the air never warms, cycle after cycle.
- Any warmth, scorch, or smell at the outlet, plug, or breaker.
Typical professional repair cost: Electrician visit to repair the outlet, cord, or breaker connection typically runs $100–$300 including labor.
Frequently asked questions
Why does the dryer tumble without heat on L2?
One 240-volt leg feeds the motor circuits while the heater needs both legs. With one leg down, everything that runs on a single leg works — spinning, lights, controls — while the heater, needing both, stays cold.
Can I test the legs myself?
Carefully probing an outlet with a meter takes you into live mains territory; opening the panel or testing under load crosses well past DIY. Especially with a half-tripped breaker or burned connection, let a licensed electrician.
Was it a mistake to plug the dryer in somewhere else?
A dryer moved to a new outlet is exactly where L2 shows up — the new location's wiring may be wrong, or the cord was damaged in the move. An electrician validates the outlet before anyone blames the dryer.
