You have to have a simple multimeter to perform the troubleshooting. You can find the instructions in one of our previous posts: dryer willnotheat & timer wont turn off

Use the breakdown diagrams and Replacement parts for WHIRLPOOL LER7646EQ2 | AppliancePartsPros.com

I have the same problem on the same model. I checked continuity of the element and the thermal fuse...both checked with the same amount of resistance as the new parts I ordered from you guys. I checked the power coming into the dryer and I have 240V (hot to hot) coming in. I then turned the dryer on and checked the voltage at the thermal fuse and it's 240V (fuse to hot). I get the same reading at the element (element to hot). New element is installed, but it does not heat.

Thanks,

-mike

Mike,

I"m afraid I did not get it clear. How did you measure the voltage at the heating element?

I put one lead on the element's connectors (both gave me the same result) and one lead on the black wire from the cord coming from the wall. Using one lead on the red wire instead of the black gacve me zero voltage which tells me that the dryer is using that phase to power the element, correct?

The heater needs 240 VAC. You have to disconnect the wires from both heater terminals and measure the voltage between each of the wires and the dryer chassis while the dryer is on. The correct readings is 120 VAC on each wire and 240 VAC between them. Make sure the wires are not touching any metal parts and each other. Be careful not to electrocute yourself.

You also may want to check the thermal cut-off and the high limit thermostat (#9 & #15 on the diagram) for continuity.

If any one of them is open, the heating element would not work. They both coming as a kit.

- The thermal cut-off kit Part number: AP3094244

Part number: AP3094244



Gene.
P.S. Did you remove the wires from the heating element when you checked it for continuity?

Yeah, I sure did.

Looks like the culprit was the thermal cutoff (#9). No continuity. Thanks for pointing that one out to me. Time to order more parts!
