Hello, it is always possible that the thermostat is the problem, however about 95% of the time the thermostat is not the problem, but the furnace or heater that it controls IS the problem.

.

Trouble shooting requires you to have a multi meter and some skill with it.

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.
