We have a Gas Furnace, the name is Mars Furnace, Model No:NCF-125, it is made by Pacific Gas Heating Co. When we start the switch, the motor is working, but it is no heating, there are only cold air coming, Can anybody tell us where we should check?
Thanks

I have no information on the furnace. Look at the begining of this section for the sticky notes. They may be of some help.

i have two controls on my forced air unit, one of which is a programmable multifunction model. on that controller, there is a 'fan' switch which i use for circulating the living room air heated by an epa woodburning stove. in the 'fan' mode, the fan comes on, but no heat from the furnace.

what type of controller do you have?
