I need some diagnostic help. We have a full propane tank. A new burner plate (last year) and the blower works. We light the pilot but the knob should pop up after one minute thus lighting the furnace. It won't pop up. What part should we replace? The furnace is a 17 year old Intertherm MGH...

I have just in the last month had an Intertherm furnace installed, and since installation they have had to come in twice because they claim the starter button is not firing. They replaced it and now it is on the fritz again. It starts for about 8 seconds and cuts out. There is fuel in the tank....

I own a 1985 modular home and the intertherm blower fan on my furnace quit working is it too hard to fix or change?:confused: Also what is the cost to fix it?:eek: Please help!! :) Thank you Rachell

My pilot light comes on and ignites heat exchanger but when the cover closes the flames shut down. The blower works but heat exchanger will not stay lit. I have replaced the gas valve and the thermo couple. Suggested that damper valve needed to be adjusted - where is the damper valve
