OK, I think I was chasing my tail...

Sending a call for heat or just turning on the fan from the thermostat produces no fan at all. My problem has to be the fan like was suggested above. The lack of fan is making the heat chamber and exchanger too hot and turning off the system...it's gotta be. And some research shows I have a variable speed blower. Both elec connections on the blower are good. Yikes, this thing doesn't look cheap. And I just hit 10 yrs old on this system install this past Oct (2012)...darn. I need to get someone out to see if it's the blower motor or the module on the end of the motor. I may try to yank it tonight and then take it to a servicer for testing in the morning.

Don't do that. Have a tech come out but let them know it's a variable speed ecm motor. They should have a tool specifically to test the motor or you can simply purchase one and test it yourself. You can leave the motor installed in the unit.

They come relatively cheap to in the hundreds.

Cheap.


Expensive.

Thank you, Doc. I'll get someone to my place in the morning.

Sure thing. Most likely it'll be the module.There's a known resistor on the board in there that's known to fry on those things.

Let us know.

Interesting twist...see this thread, post #25, 26. It's not that I purposely ignored Doc ;-), it's just that I cannot find an available tech this weekend with know how to test my ECM motor...so, I kept digging here on this site, and digging and digging. Very impressed with folks here and the great detail found.

Do, check out my current status here.
