Customer loses remote Dometic loses customer (Fantastic Fan)

Here's another suggestion. May save time and energy, contact etrailer.com and ask them if the speed switch they sell will replace the old style remote sensor switch assembly. They are really cool there. I believe the switch has a center off position, three exhaust and two intake speeds.

I've got that crappy auto open/close fan in the back and an on/off multiple speed model in the kitchen.
