Look to the fan delay/defrost terminator that is located inside to the evap. It is usually attached to the evap coil. check there first.

Compressor runs bypassed thermostat with wire that turns on and off compressor,but freezer cabinet is not cold 65 degrees evaporator fan does not turn on,condensor fan on,sttill no cold


If you have just turned it on it takes awhile for the fans to come on. The evaporator coil has to get cold about (10 to 20 degrees) and make a klixion fan switch to turn the fans ON.... Is the evaporator coils getting a frost pattern on them??? If not then the system may be low of Freon.. If the coil is completely froze up and you are getting frost back to the compressor..... then you have a bad fan switch or a door switch.... If you have a wiring diagram you can trace out the wiring.... It is usually down by the compressor or control panel... hope this helps.

My Viking Freezer is three years old. The problem is the constant roaring sound it makes. No one can sit in my kitchen, family room or living room for very long before the noise from this freezer gets on...


There are several fans on your unit one on the top with the compressors, one inside the freezer, and one at the bottom. If you open the freezer and the noise gets louder or stops then you know it is the evaperater fan. Sometimes the bearings start to go and they make louder noise. Also check on the back wall for frost you could have a frosting problem and the fan blade is hitting on the ice

Freezer does not freez food at all. the compressor motor run but no cool air or freez! Please advise any solution


Since you say the compressor is running, you should check the evaporator coil inside the cabinet. Remove the back wall screws, and the back wall, to expose the evaporator. If its fully encased in frost, like a square block of snow, you have a defrost problem, heater, t- stat or defrost control. If frost only at the top, your fan is not running. If its bare of frost, all you see is the aluminum coil, you have a sealed system leak of refrigeratnt

Not pulling down to temperture


The most common problem is low refrigerant (freon). If you don't have gauges to check the pressure of your refrigerant, do this: the compressor has one small line running to the coils on the top of the freezer. That small line should be hot enough to burn your finger if you touch it when the compressor is running. Also the big copper tube running into the compressor should be cold to the touch, almost freezing. If not you are probably low on refrigerant. Without gauges and the ability to buy freon, you will need to hire a refrigeration repair service to find the leak in your system, repair it and then gas it up. But there are a couple of other things to check first. Near the compressor is a radiator like set of coils in front of a fan. If the compressor is running that fan should be running too. if not, the unit won't cool. Also the radiator coils may be covered with dust or grease. You must have a good flow of air through these coils to dissapate the heat put out by the compressor.If it is stopped up, brush the dust from the front of the coils. Look inside the freezer as well and make sure the inside coils are not frozen over. Is so unplug the unit and let the frost melt off. If that is happening you may need a new timer on your drfrost system.

The inside of unit is only reading 20 degrees. Door seal is okay.


Start off by cleaning the condenser coils. If you get up on a step ladder or chair look for the radiator in front of a fan. This radiator gets hot when running. If the air flow is stopped by dust or grease in the coils ther freezer will not work properly. Be sure the fan is running also whenever the compressor is running. The next most common problem is that the inside coils are frozen over. Your unit must defrost 3 or 4 times per day. When the door is opened frost accumulates on the inside coils and will eventually cover the coils with ice if your defrost cycle is not working. If the coil freezes over the temperature will go up, the compressor will continue to run and it the temperature will continue to increase. Check the inside coils for ice. If there is ice, you will have to unplug the unit and let the ice thaw completely before restart. If the unit pulls down to 0 after restart, it was probably frozen over. If that is the case you will need to either increase the number of defrost cycles or verify that the defrost cycle is working. Try this and repost if that does not resolve your problems.

The compressor on my refregerator seem to be overheated it is a side by side the insides of the doors are warm and the freezer will not free but it is running there is cool air in freezer


The doors should be warm. There or heaters in the doors or what they call a yodelers loop in the frame around the doors that keeps condensation from forming. Make sure the fan if blowing on the compressor and the fan inside the freezer is also running. If so be sure there is no ice built up on the bottom inside back panel of the freezer. If so you will have a defrost problem and the coil is full of ice and not allowing the air to flow through it and cool the fridge. If there is ice, the heater behind the panel is most likely bad.

Fans inside freezer will not turn - no cooling - compressor fan underneath is turning


The fans are controlled with a clixon that has a cut in at 5 degrees, and cut out at 20 degrees. If the unit is running and the fans are not comng on then I would have to say you are out of freon. But your condensor fan could be running and the compressor NOT be running which could be a problem with your compressor. Find out if your compressor is running by taking an amp draw. If compressor IS running then you are low on freon. If the compressor is running and your evaporator coil is cold and your fans AREN'T coming on then your clixon is bad.

Freezer wont freeze, compressor always running, refrigerator not cold


HI,

If the refrigerator isn't cool, you need to answer some questions, then see if the compressor is running.

First, answer these questions:

  • Is the refrigerator completely dead? If so, see “It's stopped completely.”


  • Is the thermostat knob turned to the proper setting? If not, reset it.


Next, see if the compressor motor is running

The compressor is a football-sized case with no apparent moving parts. It's on the outside of the refrigerator at the back near the bottom. If it is humming or making a continuous noise and your refrigerator is still not cooling, there may be a more serious problem with one or more of several different components, we recommend contacting a qualified appliance repair technician for further help.

If the compressor is not running but you do have power to the refrigerator, there may be a problem with one or more of these:

  • The compressor


  • The Thermostat


  • The overload, relay, or capacitor


  • The defrost timer


  • The condenser fan motor


Cooling is poor For an overall understanding of how refrigerators should work, read about refrigerators in the How Things Work section of our website. A refrigerator or freezer that is cooling, but cooling poorly, may have a problem in one of several areas:

Evaporator coils
Condenser
Poor cooling is often the result of a heavy frost build-up on the evaporator coils or a condenser that is clogged with dust, lint, and dirt.

Evaporator coils Poor cooling is often the result of a heavy frost build-up on the evaporator coils. You can't see these coils without removing a panel on the inside of your freezer. A sure sign that there is a build-up is the presence of any frost or ice build-up on the inside walls, floor, or ceiling of the freezer. Such a frost build-up usually indicates a problem in the self-defrosting system or damaged door gaskets.

The refrigerator is supposed to self-defrost approximately four times in every 24 hour period. If one of the components in the self-defrosting system fails, the refrigerator continues to try to cool. Eventually, though, so much frost builds up on the evaporator coils that the circulating fan can't draw air over the coils. There may still be a small amount of cooling because the coils are icy, but with no air flow over the coils, cooling in the refrigerator compartment is quite limited.

Here's an inexpensive, though inconvenient, way to determine if the problem is with the self-defrosting system. Remove all of the perishable food from the refrigerator and freezer, turn the thermostat in the refrigerator to Off, and leave the doors open for 24 to 48 hours. (Be sure to have several towels ready in case the melting frost and ice causes the drip pan to overflow). This allows the refrigerator to defrost "manually." When the frost and ice build-up has completely melted away, turn the thermostat back to a normal setting. If the refrigerator then cools properly, it indicates a problem with one of three components in the self-defrosting system:

  • The defrost timer


  • The defrost thermostat (also called the bi-metal switch)


  • The defrost heater


If it still does not cool properly, there may be a problem with the refrigerant level or the compressor. You may need to consult with a qualified appliance repair technician to further diagnose the problem

Condenser Self-defrosting refrigerators all have a set of coils and a cooling fan, usually under the refrigerator, that need to be cleaned regularly. If these coils get coated with dust, dirt or lint, the refrigerator may not cool properly. The coils may appear to be a thin, black, wide radiator-like device behind the lower kick-panel. To clean them, disconnect the refrigerator from the power source, use a refrigerator condenser brush (see the Appliance Accessories section) and your vacuum cleaner to clean the coils of any lint, pet hair, etc. You may not be able to get to all of the condenser from the front, it may be necessary to clean the remainder of the condenser from the rear of the refrigerator.

Freezer defrosting


If this is a frost free freezer you may be he\aring the fan motors run and not the compressor. I suggest you call a qualified and trustworthy repairman and have him look it over for sure.
Short if that you'll need to feel of the compressor to see if its hot or cold. Vibrates or not. See if the fan motor under it is running or not. See if the inside fan is running or not

If either fasn is out start there as to why and effect repairs. If the compressor is cold It hasnt been running for a while and you will need to check voltage at the compressor and if t\you have voltage there you need to try new start components to see if it will run. If no voltage there check the thermostat (and if self defrosting) the defrost timer.

After this you can see why I suggest you call a quiulified repairman. way too many things to consider and keep you from making a correct diagnosis

If this helps you polease rate me as high as you can and thank you for using fixya.

Frost over the box tells me that you do have refrigerant flowing through the evaporator coil. If the coil has a defrost element as you stated it should also have a fan for circulating the cold air. Apparently your fan is not operating.
