Bouncing Relay on Gas Furnace Controller
Have a Bryant Plus 80t energy efficient Gas Furnace that is fairly new (@ 2 years) that fires off and heats correctly, but when it reaches temperature on the thermostat, shuts off with the relay clattering as if bouncing on its contacts. Question: Is it dangerous? What relay is it? Is it on the control board and does the whole control board need replacing? Looking at the schematic for the circuit it looks like it might be IHI/LOR or the Inducer motor Relay (SPST), or MGVR-Main Gas Valve Relay (DPST). Comments?
