Hello,

So far it sounds like a bad heating element sequencing relay or a bad heating element.

.

Take close up, exceedingly well focused photo's of the wiring diagram glued inside the furnace/air handler door, and the printed circuit board mounted on the blower, , that shows where the thermostat wires connect, and I will mark them up with trouble shooting instructions.

Use the 'add files' link next to your send button to get the photo(s) to me.

.

We can go from there with training, coaching and diagnosis.... without a time limit, In depth with as much detail as needed .

.

When we finally get the situation solved, please select the 'finish and rate your expert link' near the top of your page and click on it.

.
My goal is to give you the best experience possible! I hope I have earned a 5 star rating! Please remember to rate my service by selecting the 5 stars at the top of the screen before you leave today. If you need more assistance, please use the reply box and let me know.

It’s pretty tight in there. The circuit board is mounted on the top. The furnace itself is horizontally mounted, air flow is left to right while looking at the wiring diagram. The 5-amp automobile-type fuse on the circuit board is not blown. I hope that the photos are suitable. Thanks for your help.
