VIKING FREEZER FROST BUILD UP

Check the freezer door gasket! Frost build up along the front edge of the freezer indicates a poor or broken seal. It could also be packaging or plastic bags on top of the freezer getting into the door opening and allowing moist room air into the freezer--make sure nothing on top of the refrigerator is getting into the door or jamming it open.

im not sure if still is the case.but there used to be a timer that shuts off the refridge so it self defrost. it is set to do this 1ce a day so the ice or frost does not build up.it is called a defrost timer. if it fails it will not shut down the fridge.most of them are near the front behind the grate.

Check your freezer door gasket is sealing properly.

check the defrost heater in the evaporator compartment at the rear of the freezer for continuity,then check your defrost control if the heater is o.k. be it either an adaptive defrost or a timer type defrost control

Hi, this sounds like a problem with a blocked defrost drain. For full instructions on clearing the drain from my tips click HERE . If you have any other questions please feel free to comment. Mike

check the door gaskets for air leakage

Suddenly having the same problem. Any solution?

hi The limit switch is found only on frost-free refrigerators and freezers. Its function is to keep the defrost heating element from exceeding certain set temperatures. If a refrigerator has lots of frost in the freezer compartment, the problem may be the limit switch. However, other components -- the evaporator fan, the defrost timer, and the defrost heater -- can cause the same problem. Check these for malfunctions, as detailed below. If these parts are in working condition, the problem is most likely in the limit switch. Don't try to fix the limit switch yourself; call a professional service person for replacement.

Sounds like a defrost problem. Check to see if there is any frost buildup in the back wall of the freezer. If so, it is not defrosting as it should.

• possible causes:

1. bad defrost timer/control board
2. bad defrost heater (in freezer)
3. bad thermo switch in freezer

If you don’t know what these are then unplug the machine and let the ice melt in the freezer overnight with the door open. Then try it the next day, if is cooling fine then you need to have a service person replace one of the above items.

• if you already checked this and think it is a different problem then let me know, i will help you figure it out.

Check and see if your evaporator fan motor is working in the freezer. Also, if your defrost system is not working and your evaporator coil is frosted up, you will not get any cold air to the refrigerator section. You should see alot of frost on the back wall of the freezer where the evaporator coil is located. If your evaporator fan motor is working and there is no frost build up on the coil, the air diffuser to the refrigerator section may be the problem. Put your hand in front of it when the evaporator fan motor is running and feel if any air is coming thru. There are a number of conditions that can cause your problem. This should get you started!
