I have the same problem at this very moment. I have two furnaces, one under the fridge that send one duct forward and handles the bedroom and rear bath. The one under the kitchen sink is not turning on. No power found to the reset switch. I have only found one fuse in the rear bath electric panel for furnace/AC and it is good. Are there more fuses somewhere that I am missing?
One clarification - I see both zones for furnace on my thermostat.
