I sent them your pic and asked for a reevaluation of their denial. Doug
This is Dometic's response. You have to go to your dealer or service center to do this. They will not deal with you directly on a warranty issue. Doug
"The area of question and the wall panel color matches the picture previously submitted. If you would get the customer information, model and serial of the air conditioner, DOP and unit information we could see about replacing this t-stat as a goodwill".
Sincerely,
Dometic Corporation
