This Hurricane had finally become quite reliable the past few months as we make our trek north. We are now at the northern Oregon coast and a problem became evident when we got here. The furnace starts like normal, the register fans blow over the heat exchangers, then after about 5 minutes the furnace goes off. No red light, no LED errors on control board. The registers continue to blow cool air. Let it sit long enough and the furnace will fire up again with the same results. I’ve tested with the front zone Duo-Therm thermostat and then with the rear, so I guess I can rule out a thermostat issue. Nozzle cleaned and all hose connections snug. We are going to be in Vancouver for a few days so may drop by ITR, but though I’d see if any of you guys had any suggestions. It seems there should be some signal sent from the furnace to the thermostat to shut down the fans when thermostat satisfied with reaching heat level. BTW, this is an older Hurricane, 1998. TIA
