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

CauseHow likelyDIY-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

  1. Check the dryer breaker: a double breaker has two handles and both must be on — a half-tripped one drops a leg.
  2. Confirm the dryer is plugged fully into its outlet and that the cord isn't damaged or pinched.
  3. 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.
  4. 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

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.
