Found furnace running but shutting off on thermal limit, the blower wouldn't start because of a weak capacitor and worn blower motor, removed and replaced with a new capacitor, cycled unit multiple times, explained that the blower may go out and need replaced in the near future, all operations ok at this time.
Found unit won't light, tracked it down to not getting natural gas from the meter, opened up the gas line at the union and nothing comes out. Gas flow issue will have to be resolved before we can do any more to the furnace, not operating currently.
