Can I fix Whirlpool code L2 myself?

Start with these safe checks: Check both breakers for the dryer. Electric dryers use a 30-amp double breaker, and if one side trips, the dryer runs but won't heat. Turn the breaker(s) off for 1 minute, back on, and start a Timed Dry cycle. If L2 persists, have a qualified electrician check the 240 V supply and the cord connection.

When should I call a technician for code L2?

If L2 persists, have a qualified electrician check the 240 V supply and the cord connection. Unplug it or switch the breaker off before you remove any panel. Don't test or replace wiring, control boards, heating elements or motors under power. If you see scorching, smell burning, or the breaker trips again, leave it off and call a qualified appliance technician or electrician.
