Tech was sent out to re-diagnose and verify previous findings. Tech found the thermostat blank upon arriving. There was power to the unit but the low voltage fuse was not on board and tech located a blown 3 amp fuse in compartment. Tech installed a new fuse and control started clicking and LEDs cutting on and off. Tech removed thermostat from the wall and temporarily connected to the control board with short piece of thermostat wire. Blower cycled on and off, then the induce cycled on, relay on board could be heard click and the LEDs went out and back on. Tech diagnosed the nano control board faulty. Board will not send out low voltage to the gas valve or ignition control board to initiate ignition. Tech was able to get ignition board to spark briefly but not long enough for burners light. There is some signs of wires rubbing and possibly shorting to the blower motor module. Unit could have multiple challenges, due to age and possible high repair cost it is recommended that unit be rep

Found the infinity system continuously cycling in heat. Evidence that the System has been messed with before. Burners were loose. System resets and recycles automatically right when the spark ignitor sparks for less than Half a second. Tech eliminated the ignition control board out of the circuit and same challenge persist. Tech then removed the wires out then gas valve and same challenge persists. Tech believes the main control board is shorting out internally when it calls for heat. Tech recommends replacing both the ignition control board and main infinity control board as well and suspects a shorted gas valve(coil at the valve). Tech connected everything back.

Need to schedule a field supervisor to speak with the homeowner to provide him a system replacement quote. Costumer is not interested on having another communication s
