temp sensor
 
I'm not sure were the temp sensor is on a RHEEM furnace model UGAC-080C. Once I locate it were is a good place to purchase one.

Thank Robert

How do you know it's bad and what caused it to go out? Flame roll out switches(temp sensors) trip when a flue is plugged,something wrong with the inducer or there's a hole in the heat exchanger. Limit switch fails because of not enough air flow or the furnace is grossly over fired. It's also a temp sensor.

Found this on another site
"The furnace lights up, but the blower will not turn on if I have the thermostat in the auto position. The blower will turn on if I turn the thermostat to the fan position."
and his fix was
"I changed the temp sensor and everything is working like a champ."

The issue the other guy had is the same exact issue I'm having.

That would be a fan limit switch. It's located in the front of the heat exchanger. New ine eill need to be the same length.

Need to be the same length is supposed to be what that says
