12-12-25 The east garage area direct fire heater is not working. Upon arrival, I turned the disconnect on blower motor came on and started humming found the 3 pole disconnect switche bad one leg was not pulling in. I was able to work to switch on and off until all three steps made a good connection you still need to replace this disconnect. Start the system blower motor came on properly thenI was getting a failed ignition module (3 blinks). I was getting 24 V out of the module to the gas valve after tracing the wiring down. I found that the high limit manual safety was tripped. I reset the limit system came on, but also it tripped off again on me. I found the damper wasn’t fully open. I’m pretty sure the damper motor drive motor has failed, currently is it is locked open. At this point, the system is ruuning. we need to get a proposal for the disconnect. There’s still a belt that needs to get replaced and also look in replacing the damper drive motor. See pictures for the Model and
