I have an upright freezer there is no cold air coming out.You can hear the compresser kick in and fell some air but not cold air.What could my problem be.

Sounds like its got blockage.
There is a channel that allows cold air to "fall" into the bottom chamber. There is also a return. Typically the "fall" chamber is choked with either something that fell in and was trapped, frozen solid with ice or algie has grown and closed the hole.
The best thing to do is empty it completely and inspect the drop channel.
Put all your frozen goods in ice chests to keep them from thawing out.
Good Luck.

Is the compressor relay bad?

If it says OFF on the display, have you got a manual to say how to put it back on?

If your freezer is a frost free, then it has probably stopped in a defrost cycle. The defrost timer is in the back lower left side of the unit, it has a little nub in the center on one side, if you can turn it clockwise and the unit comes on, you will need to replace the timer part #297318010

Hello,

Fan problem is one of the most common reasons for the freezer to start failing, this is called "frost free failure." Ice can build up on the evaporator coils over time, and this ice builds up until it starts blocking the fan. The fan is responsible for circulating cold air throughout the freezer, so if it is blocked the freezer will not be able to freeze any food. You can usually check this by removing an access panel in the back of the freezer to inspect the coils. If ice is built up on the coils, a hairdryer can assist in defrosting them.

It's also possible that the fan is not running at all. If the fan is burned out or the motor isn't running, cold air can't circulate through the freezer and everything will melt. You can normally hear the fan motor switch on and off from time to time. Listen for it and if you can't hear it coming on for an extended period of time, the motor may need repair or replacement. The wires connecting to the fan may be the problem, preventing the fan from receiving electricity.

Several other problems could be keeping your freezer from freezing:

There could be leaks in one or several of the hoses in the refrigerator, which results in the cold air being lost instead of circulating properly throughout the fridge and freezer.

If you have the freezer so full that the cold air can't circulate, your food will thaw even though the freezer isn't malfunctioning. Always leave some space open in the freezer and try to not store food right up against the cooling vents.

The thermostat might have shorted out, which means the freezer can't accurately determine how cold it is. If this is the case, the refrigerator would probably not be working, either.

If your defrost drain becomes clogged, the water in the line will just refreeze over and over again, which could damage the lines as well as the fan. Always check the drain and make sure no sludge is building up in it if you have a self-defrosting refrigerator.

Always try to keep the freezer door closed for long periods of time. The more the door is opened, the more warm air is let in and cold air is released. If the door is opened frequently, the freezer could be warming faster than the fridge can cool it, which will thaw your food.

I hope this helps........

Take care.

without getting all technical, look for the condenser coil and be sure it is clean. Some are under the refrigerator and can be accessed by removing a "kick plate." Some are under and in the back and can be accessed by removing a cover with a few screws. Some units have a small fan that moves air over the condenser coil. Look for it and see if it is running. And then there are some that have coils that run up the rear of the unit and when it is pushed back against the wall, the air can not circulate and can cause this issue. This is the simple first step to do before getting a service tech involved.

something easy to try is to clean the evap. usually on the bottom. warm soap and water, or compressed air usually does the trick. it's the easiest thing to try.

My children left the freezer open overnight now the compresser want kick on... what can I do?

Either the compressor is failing or it has lost some freon which means there is a leak. The sealed system needs serviced.

Coils are probably underneath. remove the grille at the front (usually you just rotate it down to pull off) and then vaccum inside with a wand. If there aren't any coils there either, pull the machine out from the wall, and remove the lower panel from the back side. Inside you should find a fan next to a coil. Make sure that fan is working, and if it isn't make sure it is getting power.

Vacuum out as good as you can, and if you can use compressed air to blow it clean, even better (vacuum first because it will kick out a lot of dust).

If vacuuming the coils doesn't work, then you probably have a freon leakage problem, in which case it is probably not worth the cost of repair.
