Does your Dometic refrigerator have frost on the fins?

Mine will frost up when I have to open the fridge door in Midwest or Great Plains summers, or any time of year in mid-South or on the Gulf Coast. Was 88F today with dewpoint 84, my glasses fogged up stepping out of 80 degree house.

On the other hand, no frost in high desert of Colorado Plateau, most of the time, but it can get humid during autumn. No frost ariund Phoenix most of the time.

So whether or not fridge frosts up will depend on how much moist air you let in.
