Frost build up is NORMAL on RV absorbsion refers. The fin temp will be 10 degrees COLDER than the temp of items in the refer----25 degree fin temp--35 degree temp in the refer of the items. Your model has a 48 to 54 hour defrost timer ONLY if left ON continuously. If you turn it off and on again before that 48 to 54 cycle the timer starts over. You do NOT have any defrost button, NO refer (RV) has a Defrost button. The defrost time just shuts the refer OFF for about 2 hours to let the fins melt any ice/frost and then it starts up again. Ice/Frost on the fins just indicates that there is humidity in the air. Make sure you backside drain line for the evap pan has the check valve in it to prevent moist(humid) air migration back up into the refer. Doug
