We have a Whirlpool LER7648PQ0 Electric Dryer. It worked fine 2 days ago, we moved it into our new house and can't get it to start. Has proper incoming power, light inside works, timer works (when you set it to the beginning of a cycle and push the start button, the knob rotates as if it's running) .... doesn't turn on (rotate or heat) though.

SOURCE: dryer runs...timer wont rotate and wont heat up

Good day,
Timer woun't run if there is n heat.
1. Check to see you are getting 230 volts to the machine. The motor uses only 115 so is not a good indication.
2. Remove back cover. You will need an ohm meter to test the components.
A. In the center bottom is a skinny white bakelite device held on with one screw. Remove one wire and check. It should check zero ohms. If not replace.
B. On the bottom right is a canister with the heating element terminals sticking out. They should test at 30 or less ohms. If not replace the heating element.
C. There are about 3 other limit thermostats in the area you're working. They should all check at zero ohms. Replace as needed.

Below is a tutorial on changing a heating element.
