I'm replacing the roof top AC unit on my 77 Kingsley. The fan comes on all three speeds OK - it just doesn't cool anymore. It's a Brisk Air Duo Therm Mark IV unit. Shroud is good - ceiling plastic piece is OK but repainted. Switches work. Any and all pieces can be picked up for free almost any time in Escondido, CA. It's still on the coach and will soon be removed.

Hum, maybe this modification would work?

Thank you for the information. I wondered about the delay device, but just decided to go ahead with a new unit.
