Question about Honeywell Electronic Programmable Heat/Cool Thermostat - CT3300A100 Heater
My thermostat is showing 63 inside. I have it set for "heat" at 70. The furnace will not come on. I changed the batteries and the furnace came on for about 30 seconds, then turned off.
Turn off power to furnace and open the front panel and see if you can see burners and gas valve and Hot surface ignitor.
If you can. turn furnace on and watch to see if the ignitor glows.
Let me know what you find. If it doesn't glow you probably have a faulty Hot surface ignitor.
If I had make and model number I should be able to find the part
