The best way would be send a real tech out. One that has sense to put a temperature probe near the limit, disable the fan, and light the fire. Watch and see if and at what temperature it trips at. The apprentice should be trained on preforming PMs before thrown to the wolves to avoid damaging the equipment or worse, himself.
Replace it silly. If you dont know how to test it, then its gotta be bad. Replace the thermostat while you're at it. Install a few of those reverseflo@ductboosters too, just for good measure. Bubba
