I have an older intertherm furnace model #mghb070abfc-09. We have a programmable thermostat on the wall. About 6 months ago when we set the temp for the house the unit would click on like normal the gas would heat up the chamber and turn on blowing warm air. But it would not stay running it cycles on and off every 30-45 seconds. The fire is still burning and without my manual all I have is the wiring diagram in the inside of the electric cover. I do not know what to check first, if it is a sensor disc or a relay or a contact. Any help would be great as I am a truck driver and not home very often. She is afraid of using it and only uses the fireplace and it is not enough. Thanks Tom
