L2 on a Whirlpool dryer is a power problem, not a broken dryer part: it means one of the two "legs" of your 240-volt supply is missing or low. Electric dryers use 120V to tumble and the second leg to heat — so with L2 the drum spins fine but you get little or no heat. Here's the order a tech works it, and it usually points at the outlet, cord, or breaker rather than the dryer itself.
The most common cause. A dryer breaker is a double (two-pole) breaker. If one side trips — or the pair only half-resets — the dryer loses one 120V leg, so it runs but won't heat, and throws L2.
Check it: Find the dryer breaker in the panel, flip it fully OFF, then firmly back ON (they can look "on" while actually tripped). If heat comes back, that was it.
Dryer outlets and cords carry a lot of current and can burn, loosen, or corrode at a terminal — losing one leg. You'll sometimes see scorching or smell it at the outlet.
Check it: With the dryer unplugged and breaker off, look at the outlet and cord ends for burn marks, melting, or a loose connection. A burned outlet/cord is a straightforward (but power-off) replacement — best done by a tech/electrician.
A bad connection back in the wiring or panel can drop one leg of the 240V feed even when the breaker looks fine.
Check it: This is an electrician/tech diagnosis with a meter — if the breaker and outlet/cord check out but L2 stays, the supply wiring needs a pro.
Repair — and often it's not even the dryer. Most L2 codes trace to the breaker, outlet, or cord (cheap fixes), not an expensive internal part. It's worth diagnosing before assuming the dryer failed.

Because L2 means one leg of your 240V power is missing — 120V still tumbles the drum, but the heating side has no power. Start by fully cycling the dryer's double breaker off and on; a half-tripped breaker is the #1 cause.
Flip the dryer's breaker completely OFF then firmly back ON, and check the outlet and cord for burn marks. If heat doesn't return, the outlet, cord, or house wiring has a bad leg — a tech or electrician measures the voltage to pinpoint it.
Usually not — it's almost always a power-supply issue (breaker, outlet, cord, or wiring), which is often a cheaper fix than an internal dryer part. Your $50 Quick Check credits toward the repair if it turns out to be the dryer.
