Whirlpool L2: Low or no line voltage to the heater

L2 means the dryer sees too little incoming voltage to power the heating element, so it tumbles but will not heat. It points to the home power supply or the cord, not usually an internal part.

Before you start — unplug the dryer, and on a gas model shut off the gas supply. Let it cool first — the drum, heater and exhaust can be hot. If a step involves the heating element, wiring, or opening the cabinet and you're unsure, stop and call a qualified technician.

Step-by-step fix

1Reset both breakersAt the panel, fully switch the double 240V breaker off and back on, since only one tripped leg cuts the heat.
2Unplug and inspectDisconnect power and check the cord and terminal-block screws for looseness, corrosion, or burn marks.
3Test the outletConfirm the dryer outlet is wired correctly and delivering full voltage on both legs.
4Try a resetLeave the dryer unplugged for a minute, then restore power and restart a heated cycle.
5Call an electricianIf low voltage persists, have an electrician check the household wiring and breaker.

Still showing L2?

If you’ve worked through every step and L2 keeps returning, an internal part likely needs testing and replacement. That’s a job for a qualified appliance technician, who can measure the suspect part against the service-manual spec before replacing it.

Which models this applies to

Whirlpool dryers. Whirlpool electric dryers on 240V service; L2 signals a supply-side voltage problem rather than a dryer part failure.
