Lenox Thermostat Problem


-AC meggase on unit, (running on battery power) heat not turning on. I keep taking the thermostat off the wall and putting it back on, I even pulled out the connection prongs on the back of the thermostst (Lennox Programable) so it would make a better connection with the pins on the wall plate. The furnace will come on for a few minutes then go back to -AC (batteries). Is this a problem with the Thermostat itself? And if so should I try buying a new one and replace it? Last question, should I buy a lennox thermostat or doesn't it matter, are they easy to replace?
Thanks for all your help!!!!

I don't think it is a stat problem. Do you have 24 volts at your furnace c and r and is it a gas furnace. Norm when you see batt you lost 24 volts. Could be a limit switch that may be why you have power for a second.

I have certain techs that specialize only in oil. Oil should be serviced yearly. It is not for the diy people.
