NHBoomers-
First off, welcome to Winnieowners!
Second, you should add a signature to your user profile. It usually includes the year, make and model of your coach, but can include other information. A signature is appended to each post. To create/edit a signature, click on the "User CP" link in the orange bar at the top, then click on "Edit Signature."
Re: Refrigerator. You would do well to join the sister site to Winnieowners, iRV2.com, and post there. You should get a response for "Old-Biscuit," who is the current reefer expert.
Here is a link to Norcold and Dometic posts by "Old-Biscuit" on iRV2. Searching them might give you an answer, but fastest would be to post on iRV2.
You can often use the same user name and credentials on iRV2, so you won't have to remember a second password (for instance).
Some reefer problems have simple fixes, and it's a tough time to buy replacement units. After searching/posting, I might be inclined to find a reputable mobile repair company to assess your reefer.
