mikerodg Report post Posted March 28, 2017 I thought I would give a remedy for frosting refrigerator fins. My Dometic Dimensions 2 door refrigerator was frosting badly due to a bad doors seal and poor internal circulation. I purchased an oem door seal from Deyers for around $200. I did not like to size and thickness of the ones found at Walmart. It installed easy enough. I still did not have a perfectly tight fit so I installed a small wood shim where the door latches. Its very tight now. I also installed a dual fan with a switch onto the fins and wired it into the door light with a piggyback connector . It is on all the time. A little over a week now and no frost.
