I have a Kenmoore HE5 Elite dryer that won't start. Model number is 110.87701700.
The L2 error code indicates low voltage to the dryer. And this is most commonly caused by a poorly wired 240V wall outlet or loose connections to the dryer. Ideally, If you are inclined to test the voltage, you should do it at the dryer where the wires are attached in the back. BE CAREFUL; YOU ARE DEALING WITH 240VAC. YOU CAN BE KILLED IF YOU TOUCH THE LIVE WIRES! With the leads of the voltmeter across the outside wires, you should measure 220 - 240 VAC. If you do, then have someone press the start button. If the voltage drops significantly, (drops to less than 200VAC), you've found the problem! Turn off the circuit breaker to the dryer (and make sure you don't have any voltage at the outlet anymore.) Now check to make sure the screws that hold the wires at the back of the dryer are tight. If they are okay, then your problem is either at the 240V wall outlet or at the circuit breaker box. I'll let you take it from there; just make sure there is no power at the outlet before you remove the cover screws.
