Suburban Furnace has 2 Amp Phantom Load when off
Folks, Just took a trip in my fifth wheel. 2003 Cougar with suburban furnace. It had been off the road for about 20 months so I checked out all the subsystems. AC, Fridge, Furnace, Water Pump, Hot Water Heater all seemed to work fine. My generator is not working so I was dry camping. Found that I could not get through my second night without a low battery setting off the CO/Propane detector. That will wake you up! Was able to run the tow vehicle intermittently to keep things running, but clearly had some unexpected power usage. Back home I was able to identify that the furnace circuit is drawing 2 amps with the thermostat in the off position. So my current assumption is that there is some short in the furnace or some circuit is energized which should not be. Anyone experience anything similar on a suburban furnace? It is an SF model, I think the SF30F, but I am not sure. I pulled the furnace fuse for now, so I dont have that drain, but would like to track done the issue. Has anyone experienced anything similar? Any help is appreciated. Thanks Andy2.2KViews0likes9Comments
