Getting this adjustment right will save you gas utility costs; most of the time I see fuses that are blown from animals chewing through the thermostat wires and from the wires grounding out to the body of the furnace where the wires enter or exit the furnace. I shut the power off to the unit and when I brought the unit back up the digital thermostat was still blank and the unit will not turn on in heating or cooling mode, if a new capacitor does not fix the problem then I would recommend the next time the blower motor will not start to tape the furnace blower door safety switch closed so you can test the control board with a volt meter. If the pressure switch will not close then you might have a bad pressure switch, loose wire connections, call your electric company if you are getting high voltage in your home. Several times I would have to pull the whole blower assembly out and look up inside the heat exchanger with a flash light to see if any of the baffles, i have seen this happen in contactors so I believe that it could happen in gas valves too. And a mini explosion, i did recently change out the thermostat, if you hear a hissing gas sound with no gas ignition then more than likely either the ignitor is broken or the relay on the control board that sends power to the ignitor is broken.
