ok what do you need

What is the model number of the A/C and the model of your thermostat? I need to be sure that there are no compatibility issues here. Is your ducted or not?

I can give you a call as soon as Customer Service clears your CC payment for this. It may have been a Fraud Alert issue.

Has the card gone through yet?

Not yet, but that part number you gave me for the ceiling box should be a #3107206.017 and is a manual controlled air box with ceiling controls. There was only one heat strip that would work with that one and that part is #3101121.030 and those are NLA from Dometic. It doesn't mean you won't be able to find one, but they may be scarce. I can see what I can find at my supplier when I get into my shop. That would be in a few hours as I am in California.

Can I send you the only tag I can find in the air box?

I am attaching a link to a dealer who shows they have one still. https://www.makariosrv.com/dometic-old-style-non-ducted-heat-strip-3101121-030/

Thanks

If you want that you might want to get right on it! Getting scarce! And you are most welcome! If you need more here then please get back to me.

Ok thanks for your help

They show that part number as being superseded by a new number: (###) ###-####000

Customer reply replied 9 months ago
Ok thanks

But......I checked on that and it is for the newer BriskAir II models and will NOT fit yours. So you have to go back to looking for that original number I gave you. I will see what I can find and report back if I find one.
