Kelvinator Refrigerator has frost or moisture buildup around the door
Frost or moisture collecting on the mullion flap or around the door usually means warm, humid air is making its way into the cabinet. The most common cause is a failed mullion heater or heater flap that no longer heats periodically to melt condensation; you can check the mullion heater for electrical continuity with a multimeter to confirm. If the heater is fine, look next at door support and door guide problems—worn or misaligned supports and guides can keep the two doors from forming a tight seal. A damaged or twisted door gasket is another frequent culprit that will let warm air in, so inspect the gasket for tears or gaps. Finally, make sure a freezer or refrigerator door was not left open for an extended time, which can create temporary frost until the unit completes a defrost cycle.

01 - Kelvinator Refrigerator Mullion Heater
A defective mullion heater flap may not be able to heat up periodically to melt any frost or moisture that forms on the flap due to increases in room humidity. You can use a multimeter to test the mullion heater for electrical continuity to determine if the component is working. If the mullion heater has no electrical continuity you should replace it with a new one.

If the mullion heater flap has frost or moisture buildup, it's possible the door suport is damaged or misaligned and not allowing the flap to form a tight seal between the refrigerator doors. Inspect the door support for wear or damage and replace if necessary.
If the mullion heater flap has frost or moisture buildup, it's possible the door guide is damaged or misaligned and not allowing the flap to form a tight seal between the refrigerator doors. Inspect the door guide for wear or damage and replace if necessary.
A door gasket should form an airtight seal around the appliance's frame to keep the cold air in and the warm air out. If the door gasket is twisted or torn, gaps can form that will allow warm air in, resulting in the freezer not freezing properly. Inspect the door gasket for any damage and replace with a new one if necessary.
If the freezer or refrigerator door was left open for an extended period of time (more than 4 hours), frost may have accumulated on the food and around the door opening. The frost should go away after the door is closed and the refrigerator goes through a defrost cycle.
