Motor Number for a Dometic 9100 awning.

On a side note, did you have to lock the awning in place when you pulled the motor, to keep it from rolling up? I've read differing accounts that say you don't need to since there isn't any spring inside, but the Dometic literature says you do.

TIA

Unroll about two turns, then stick a small screwdriver or something through the hole on the opposite end through the end cap. It can be a PITA to align it with the hole in the shaft. I think Dometic tells you to jam a cotter pin in there going from memory.

Thank you all for the assistance, and advice. Much appreciated.

Now I need to look for new awning material too. Bummer.

I have 3 9100 motors in my garage I pulled from others rigs that were inoperative when replacing their motors, and had them internally rebuilt. All failed due to corrosion. It corrodes the stator. They are all identical as far as dimensions and such.

Always keep your trailer stored nose high and when the awning is out pitch it down towards the rear opposite the motor. Its the water that kills them.

That's good advice about storing it nose high, and since it is stored on a slight slope that works.

I'm pretty sure it is corroded since we rarely use the awning, and it is pulling some pretty high amps when trying to roll it up using an independent battery and amp meter. They certainly do want a pretty penny for those motors.

This is the P/n for the white end cap motor. Doug

Thanks Doug, I'm hoping the one I ordered from Ebay, new not used, will do the trick. I believe the P/N I had was 3310423.037B. I've had good luck with lots of stuff from Ebay so we'll hope my luck holds.

How the heck are you supposed to know what motor you need without taking the darned thing apart?

Why so much resistance to calling Dometic and asking? Supply any numbers you can find on your awning hardware and give 'em a call. You also haven't mentioned why you want to replace this motor, nor have you provided any details about your rig which would indicate it's age, but it's possible you might have one of those awning motors covered under an earlier recall, depending on whether you particular unit falls within the recall dates. Call 'em.

I had thought about calling Dometic, but I actually thought I could find the information faster online than going through voice mail, call centers, and customer service that often isn't much in the way of service.

I want to replace the motor because I've tested it and determined that it is bad.

I knew about the recall and the recall is for awnings that are a couple years newer than mine. The year of the rig didn't seem important since it isn't more than 10 years old, and uses the standard 9100 Dometic (A&E) awning.

But you're right too, I may have to bite the bullet and call Dometic if the motor I ordered doesn't work.

Thanks Doug, that's what I was afraid of. How the heck are you supposed to know what motor you need without taking the darned thing apart? I figured to take it apart and replace the motor, but I don't really want to take it apart to find out what motor I need to order. Bummer.
