So after waking up to a humid house and making sure somebody didn't just turn the A/C off, I put my hand to the vents and nothing was blowing. The air was 'cool', but the fan seemed to not be moving. So, off to the attic! Immediately I could here the fan ATTEMPT to start, run for a few seconds, and STOP. Then again it would try and start, spin for a few seconds, and stop. Then again it would try and spin, run for a few seconds, and stop... etc etc.
The whole time I've got a blinking sequence on the motor electric board -- 6 CFM LED blinks. Pause. 6 LED blinks, pause....
With 3 grandparents in the house and a hot week coming up, I thought I'd give this a shot before I reach out to a tech tomorrow.
I'll post pics if anybody needs.
