can't get the furnace to run . checked everything i could with out
removing the furnace. is there a switch on the ac?

[jcurtis934]

You mean switch on furnace instead of ac as written? Yes, there is a switch on the furnace, only visable with outside cover removed. By what info you provided, it is guess work on how to help you. Has it worked prior to now?

Also, your furnace works entirely on 12v so if you're checking 110 you're looking in the wrong place. If the switch is on on the furnace, check your fuses and check the water in your battery.

Do I understand that you have a 2002 Model?
Their is no outside cover on a 2002 model.
Turn thermostat to heat set temp higher then room temp you should here thermostat click fan should then come on for a short period then you will here the igniter click then you will here ignition.
If this is not happening I would start checking DC fuse
