Question about Refrigerators

1 Answer

My viking drawer refrigerator quit working yesterday. Power is on, but no cooling. The manual says how to get into service diagnostics, which I did, and evidently the "mullion heater" was off. I reset it and the cooling turned on. I doubt if this fixed it.

There are one of two things,either the mullion heater is open and needs replace,the defrost thermostat located near the heater,the defrost control is not supplying power to the heater/secondly it could be the ptc overload on the compressor that is bad and not powering the compressor and needs replacing

Defrost heater do not defrost creating poor air circulation

for starter call viking with your mod and ser #
there is a hinge recall on fridge door is covered by warranty regardless of age
it can cause the air channel from freezer to fridge to ice over due to too much humidity entering fridge
this stops cooling in fridge
the viking warranty starts from the day you took possession
defrost heater almost never
sounds like you need a better servicer
ask viking for other auth servicer in your area

Broken drawer

Parts and accessories are quite expensive for appliances. Some factories may be able to sell you the part cheaper than online distributors. Check the contact information of the manufacturer from the user manual and try to contact them. If you got the appliance with the broken part or cracker, they may send another one for free (They may ask you to pay for the S&H) - If the manufacturer doesn't sell the part, they should provide you contact information where to get the part.

Viking Refrigerator problem

Try this my Mother had a similar problem, make sure the vents are not covered inside the fridgerator between the bottom and top so the cold air is able to circulate between them.

Doesn't cool

Hi, Yes, If the evaporator was not frozen over then I agree with you. The unit has lost its refrigerant charge. The only thing you can do is to have a licensed refrigeration man find the leak, repair it and recharge it or replace the refrigerator. If the evaporator is frozen over the defrost timer would be the problem. In this case, manually defrost it and it will be good for a few days until you get it replaced. kstfas
