Turned on my Spa & heater today and the heater did not start.
Checked the display and it had "Service heater' light on.
Popped the hood and the AFS light was on.
Made sense because the blower was not running.
Opened the blower to check for nests, totally clean and spins freely.
Poked my phone camera into exhaust port and the tub is dry.
It does not seem to make any sound, humming or otherwise. I'll have to double check this as one possibility is a starting capacitor I guess.

Am I missing anything?
Is there other reasons it would not spin-up?

Anyone's help would be greatly appreciated.
