Calling the HVAC experts (again)
I know, I know, not woodworking, but I know there are a lot of people here with varying talents!
My heat died last night. The problem looks like it's the blower. I used my problem determination skills to observe that the blower isn't spinning! :)
Anyway, when the system calls for heat, or you set the 'stat to fan-on, the blower oscillates back and forth for a few seconds and then quits. This is a variable speed blower that ramps up the airflow slowly and can vary the speed according to whether the system is calling for heat or cooling. It's actually pretty cool - until it dies... I know the motor is expensive, so I'm hoping there's something I can fix to nurse this along until the system is replaced (It's a 15 year old Carrier unit and I feel the end is near).
I'm hoping it's something easy like a capacitor, but I don't see a readily visible capacitor on the unit. Do these variable speed motors even have capacitors? Any suggestions or ideas for what's wrong that might not involve replacing the entire motor/blower?
