With 25+ years experience, I am familiar with residential, commercial, and industrial HVAC equipment including but not limited to boilers, chillers, reciprocating and screw compressors. I am trained in all manners of control wiring.
I currently have three HVAC licenses and Refrigeration license by the State of North Carolina. I have been in this field for over twenty years. I have been a service technician for a contractor and also worked at a state college in the repair and maintenance of steam lines and equipment. I am currently the Building Maintenance Superintendent for a municipality.
As a public service, I highly recommend to anyone with a fuel burning appliance of any type, cook stove, heater, logs, etc. to install a carbon monoxide detector. This is a low cost item considering the benefits. Also be sure to check on the detector installed, many lose their ability to detect carbon monoxide after one year and must be replaced. Thanks.

If this is a mechanical combination switch that controls the blower and has the high temp reset switch, I would start by replacing it. This switch has bi-metal in it that will over time fail. It is the
It is not impossible to have a low charge, but with a sealed system like this one, it is less than 1% of the problem. Most often it is electrical, a dirty coil, malfunctioning fan or some other problem
I would check the chimney and the old vent piping to ensure there are no obstructions. If all this is clear, you have paid for a working furnace and I would stay on top of this contractor and not pay any
