We have a Norcold DE 360 fridge/freezer which is no longer working on AC or DC. I've been told the parts are no longer available so we need to replace the unit. Any suggestions as to which model best fits as a replacement. This is a built in so it will be a painful job ($$) to remove & replace. We really don't want to use a repair service as we've already determined the parts & fridge are no longer available. Thanks for your help-love this website!
