1. 1999. There are only 2 access door makers. Dometic or Norcold. Both are available. There are different sizes so make sure you measure your existing hole. Also, a Norcold refer may have a Dometic side vent and Vice Versa.
2. DO NOT install ANY type screen on the side access door louvers. The purpose of the side door and louver cut outs are to get a certain volume of fresh air IN and up the back of the refer Cooling unit. ANY type screen material will block off about 50% of the volume of air needed to adequately operate the refer to cool correctly. Doug
