Make sure you have a good 12 volt battery, and do not count on just because you have 110 ac power that the furnace will be able to run properly. The converter will give you 12 volts but by the time you have lights and other things using some of the 12 volts it provides it might not be amble for the furnace. The furnace is one of the highest power users of the 12 volt system. You need a good fully charged battery. Then it could be dirty or out of adjustment igniter.
