Where can I find a vacuum switch of an Inter-City furnace?
I have a furnace mfd by Inter-City Products Corp. Model NUG5100BHB2. The combustion blower comes on but the furnace will not light. I was able to force it on by mechanically pushing the plunger off the microswitch with a screw driver on the vacuum switch connected with a hose to the combustion blower. Logic implies that the switch is bad however could it be a lack of vacuum for some reason. I am also unable to find a replacement switch on line.
