Default How do I know if furnace thermocouple is bad?


Fuses rarely fail on their own, they are usually an indicator of a
problem elsewhere.


We had some warm weather over the weekend, so I turned the thermostat
off. I asked my son to turn it back on, and I noticed that the fan
switch was set to "On" instead of "Auto."

Would the blower running continuously for a day or two be reason
enough to blow the fuse?
