2transformers feeding 2 thermostats and 2 dampers. Smh. 4hours later. Condenser would turn on randomly for 5minutes and shut down . Only reason I figured it out was bc the meter read 27.6volts in some spots and 28.9volts in other spots. Smh.

I tried bypassing the circuit board/damper but the voltage coming from both thermostats said 28.9volts but the output from damper board to furnace said 27.6volts......... it was using thermostat low voltage was different transformer than what the damper board sent to furnace....... bc when I sent from thermostats to outside it read nothing ,... zero volts . ... bc it was a different hot leg(different transformer) ..... smh....

Ultimately the board wasn't working right anyways, needs a new one.....
