Question about Honeywell Programmable Thermostat Heater
I have a Honeywell programable (not sure the model but 8yrs old)
I have the temp set to 22 degrees and it is 20degree and reads system on bu the furnace is not on. It will come on now and then but ignite, blower on then it shuts off. Also it will start and do the same thing if I switch it to off and then back to heat. Sometimes when it is running i will hear it ignite more then once. I have changed the batteries but no change. I am not sure if it is a furnace problem or time for a new thermostat.
Thank you in advance.
It sounds like you have plugged filters or a dirty flame sensor when you turn the thermostat off you reset the lock out in the furnace control board. first always check your filters and make sure their clean. then turn the t-stat to heat go to the furnace and listen. see if you can hear the combustion motor turn on then a little later you should hear the gas valve open and the burners ignite. if the burners ignite for approx. 3 sec then shut off you have a dirty or bad thermocouple. if you don't feel comfortable with performing repairs your self call a qualified service co. hope this helps.

It is definitely a furnace problem. Once you turn the thermostat up above room temp, it closes a switch and sends power to your burner, (gas or oil). It would seem more like a problem at the burner that is causing you problems. If you do not have experience with heating equipment I suggest you call a local repair man. Hope this helps a little
