   This is the MFG. No. (part number) for the 13,500 BTU Dometic AC:

641915C751J0

Start capacitor: 61B2D250043NNCA (old pt. no.)

3311883.000 (new, replacement pt. no.)

Run capacitor: 39-02-0270615J (old part no.)

Not sure what new run, or duel capacitor pt. no. is. Think it's 3314471.017. Check to be sure. It's important the microfareds and VAC match. SC 43-uF, 250VAC, RC 55/15uf, 370VAC. When ordering it they should be able to tell you. Shop around for best price. I got the SC from Camping World but they are the most expensive. Got the RC on Ebay for good price. These are made in China. I understand a company called MARS has USA caps, but didn't try them.Try Digikey.com. DO NOT attempt this operation unless you know what you're doing. You have to discharge the caps to handle them, or risk shock. If your AC has the symtoms as mine, don't try replacing one cap at a time. Just replace both and be done with it.God Bless~
