Help with a Twined Carrier system
I have two carrier sta58155-20 furnaces running in twin mode, single duct, one thermostat.
I had power issues and attempted to run one off a generator before I knew they were wired together. Short story, LH furnace ran for 10 mins then shut down, no error code light at all now.
Power issues fixed, now no light on LH furnace, RH has steady ready light. But no go.
First question, woudl the board have blown in the LH one or a relay or switch?
Second ?, could I swap the board out of the RH, place in LH and run only one furnace for now while waiting for replacement part? Or would this require disconnecting the Twining from them>?
