Model Number: LER5644AW0
This was a older dryer. I would guess over 12 years old.
I started the dryer to check it out and found it would run, but did not heat.
Did a quick voltage check and found I had the correct voltage (220-240Vac) going to the dryer.
Then I removed the back of the dryer and checked the thermo cut-off that is mounted on the left side of the heater case towards the top. I checked it with my ohm meter. It checked open, like a bad fuse. So I replaced it and the dryer once again would run and heat.
When you replace this thermo cut-out the replacement will enclude a second thermo cut-out. The extra thermo cut-out is located on the same heater case, but towards the bottom on the left side. You will need to install both of the thermo cut-outs to repair the dryer. If you only replace one of them it will go out again.
