Our thermostat will not turn on the furnace . The pilot light is on . It has gone on and off a couple of times overnight then shuts off right away . Does any one have any suggestions, or possibly how to calibrate the thermostat ????

This is an Intertherm heat/cool thermostat on our mobile home.

we ad a similar problem to yours. What I did is opened the unit and found out some rubber hose tubings were gnawed out by mice I simply removed that and went to the hardware store and bought a similar sized rubber tube. Then the problem was solved.
Just do a quick check the tubes and wirings of the unit for rodent damage first, rodents love to play around it and often they get too far.

are you sure the unit has a pilot flame or is the power light on the control that you think is a pilot light. look at the gas valve and see if it has a pilot position or if it just says on and off. be sure the valve is set in the on position and hasn't been left in the pilot position after relighting it. if the bottom "cake pan" on your roof jack is covered it will cause the furnace to come on and then shut down. clear the snow away from the stack. You can eliminate the thermostat as a problem if you connect the red and the white thermostat wire together in the furnace behind the top door. leave it connected for about 5 minutes to see if the furnace still short cycles.

How long has this been happening?
Mercury/manual thermostat? (Round with a dial). If it is, take the cover off. Under the dial there should be a sliding lever which will probably have the word LONGER marked on one end. Slide it in the other direction (away from the longer) one notch at a time until the furnace starts functioning normally.
Although it could be that the thermostat isn't functioning properly any longer. I had a problem with the mercury thermostat in our finished basement and it did almost what you described. I wound up replacing it with a programmable thermostat, which is very easy to do.

Is this a heat only thermostat? Standard electromechanical or digital programmable? If you can remove the 2 wires that control the furnace, usually red and white, and connect them together does the furnace go on? And then shut off when you disconnect them? If so then the thermostat is suspect, if not your problem lies elsewhere. Your basic electromechanical thermosat, Honeywell's "The Round" for example, is very hardy and reliable and is usually not the problem but if it is replace it, they are not that expensive.

Sounds to me like your heat sensor is bad.
If it's a new furnace, there is a motherboard and have a technician check it out.
Good luck

take off the therm. and take the red and white wires and put them together and hold untill unit comes on if it does replace the therm. and if not you might have a bad relay and you will need to call a repair person

It sounds like we're talking about gas here. I would suggest that you contact a qualified repairman to diagnose the problem.

sounds like it's time to replace the thermostat with a new one.
