I have a Kenmore HE4 Dryer and it won't heat. I checked the element and I have a complete connection. Replaced the cutoff. Checked the diaggnostic and all shows OK. Checked the ventor sensor and its OK. My goodness, does anyone have any idea what's left to check.

Hello Daledemp

To really being able to check electric and electronic equipment you require at least a multimeter, allowing you to follow "hot" points towards the part concerned.
Buy the cheapest electronic display type multimeter available in an electronic service parts shop. Should be no more than $ 15 to 20.

If you still have a problem - and have a multi meter - you can do more tests if you want.

Just let me know by private mail (click on my handle and follow instructions) and I will return here to reply.
If this helps solving your problem, than please rate this reply.

Success !
