I own a DFSB423 Viking refrigerator which I believe has a Drain Pan Heater Kit installed. This supposedly helps to accelerate water evaporation from the drain pan. Mine needs to be emptied like one or two times a month. In the past, tt only needed to be emptied like once a year. I should have a problem with either the defrost system in the refrigerator or a malfunctioning drain pan heater. My refrigerator also has a 24V DC "service fan" (or maybe an fan that helps evaporate the water from the drain pan) underneath the fridge that is disconnected. I am not sure if the previous house owners (the refrigerator came with the house) had this drain pan heater kit installed and had the service fan disconnected as per the drain pan heater kit instructions. I don't have the instructions so I can't really tell.
So, if by any chance, you have the installation instructions for the Drain Pan Heater Kit part number G50911853, would you be kind enough to scan them and post them here or send them in a private msg?
Thank you very much.
