Hi looking for some technical help with our HVAC system. I just replaced the blower motor in our furnace and it is running constantly since the change. I’ve disconnected it from the thermostat to isolate the problem and it still fires up as soon as the power comes on and stays that way with or without the furnace engaged. The furnace itself still turns on and off as normal so I don’t think it’s the furnace limit controller reading overheat or going bad. I suspect it could be a bad relay. The thing that really confuses me is that every morning when I wake up it tends to be off and stays that way until triggered either by the thermostat, the fresh air exchange or even me cutting the power and turning it back on gets it going again. Then it stays running until the next morning again.
