Duo -Therm 900 Series Gas - no heat! Larry Guggemos 10-6-06  
I have a Model 900 Series Duo-Therm Direct Vent Gas Furnace. It stopped putting out heat. After I turn the thermostst to on, the fan startes a few seconds later. The power comes on at the valve and then the power to the valve goes out after 6/7 seconds (ignition failure). The blower fan keeps running after ignition failure until 12/15 seconds after I turn off the thermostat (like it should). The unit uses the same valve and style ignition system as the Water Heater Unit does on this M/H.

Is there a fuse on the unit that may be blown? The schematic mentions a fuse. Do I need to remove the unit to do the needed service. I only ask this because I have trouble getting on my knees and am in the middle of the desert and it is getting cold. I have sucessfully done all the maintenence work on the W/H but am stumped with the Heater Unit??????

Help,
Larry

If there were a fuse, it would be for everything powered by 12 volts. It sounds like you have an ignition board problem. You would have to remove the unit to check for ignition. How have you determined it has no ignition?
