There is a klixon that allows the fans to run when the coil is cold enough. Check it's closing when at -12c

SOURCE: Unit not freezing , evaporator fan wont run

If this is a Bev-Air, don't think the door switch will control the fan. At the evap, there is a temp sensor called a fan delay. When unit goes into defrost mode, this warms up. Some also serve a dual purpose. It will terminate the defrost cycle at a certain temp., say 51 degrees or so, at the evap. Anyway, when unit comes out of defrost, it keeps the fan off so it allows the evap to cool quicker and to prevent circulating warm air. This could be your problem. Not a hard fix but they can be a pain sometimes. Outside chance that the unit is low on refrigerant (freon). This will not let the evap get cold enough to trip the sensor back into position to turn the fan on. Good Luck. Restaurant Parts and More carry alot of Bev-Air stuff. 1-888-814-1110. Ask for Rick

SOURCE: evaporator motors won't run

Normally, freezers have electric heaters that are energized during the defrost cycle. Once out of the defrost cycle, the refrigeration system comes on but the fans do not. This allows the evap to cool off and to prevent circulating warm air from the heaters. This is controlled by a fan delay switch. It is a small, round device that can have 2, 3, or 4 wires going to it, depending on the manufacturer. It is usually clipped on to the end of the evap coil on one of the "U" bends, near the top, inside one of the ends of the evap. Usually where all the electrial components are located. It come in several variations, but it's main function is to prevent the fans from energizing too early. Usually does not bring fans on till evap hits 20 or so degrees. Check this out and get back to me.

SOURCE: True freezer model TS49f-RC. Evaporator fans will

You are most likely correct. Most manufacturers of freezers have fan delay/defrost terminators. But keep in mind that if the box is hot, it will not stay in defrost as that is what the terminator is designed to do. Does the unit ever get cold? You may have a refrigeration problem and the terminator is good. If you can give some additional info, I'll be glad to keep assisting you to get it going.

SOURCE: Beverage Air. Model: CFG24-1. The evaporator fan

http://beverage-air.com/pdf/manualsbycategory/K%20Series%20-%20Bottom%20Mount%20Reach-Ins/CFG_CRG_KF_Series809-046A.pdf

The fan has a limit control wired in series that shuts the fan down until the coil temperature reaches 25*F. this prevents the fan from blowing warm around after defrost.
There is also a switch which is placed for the door to close. Either one may be defective.
Worst case is the freezer is not pulling down temperature wise.

GE bottom freezer stopped cooling


The unit needs two fans running and good airflow, one fan outside cools the condensor coil and the other inside the unit blowing across the evaporator. The compressor must start up. The defrost timer stops everything and switches on a heating element to defrost the evaporator for several minutes. Please verify these conditions.

Freezer not working, things to check


The unit needs two fans running and good airflow, one fan outside cools the condensor coil and the other inside the unit blowing across the evaporator coil, warming it. The compressor must start up. The defrost timer stops everything and switches on a heating element to defrost the evaporator for several minutes. Please verify these conditions. The condensor coil may get clogged with dirt and lint, the evaporator may get clogged with ice build up, or the fan may quit working due to bad bearings, need for lubrication, or burn out. The defrost timer has an internal motor and contacts which may quit working, some have a way to manualy turn it to switch its mode in case it quits working.

Commercial fan on evaporator cuts off after starting


There is an overheat klixon on the evaporator that stops the fan running until the coil gets below -11c This can take some time after startup. if the freezer runs more than an hour before the fan starting, check the klixon isn't faulty, and you have power to the fan. Also check the condenser grille is nice and clean as it will slow down the freezing process.

My whrilpool upright freeze not cutting out motor keep running continuously how can i fix this problem.


Hi, slowly get to the thermostat/control and slowly back it off to see if the unit will shut off. Now, let it stay off for 5 to 10 minutes so the pressures in the system will equalize or it won't start. After it sets this time period, slowly turn it to the colder position until you here it come back on and put a mark at the control knob so you know where it started up. You may just be in need of some cleaning. Behind the unit, you should have a lower panel that can be removed to excess the compressor, condenser coil, and condenser fan motor. Unplug this unit, remove panel and take a look with a good strong light at the coil. You will have lint build up on the front as the air is drawn back through this coil by the fan to cool the refrigerant that removes heat from in the box.After cleaning, you should be able to shine a flash light through it and see very well if its clean or not. This will keep the head pressure down to a normal operating temperature. Put it back together and start it up by plugging it back in. Watch the units operation to see if the compressor will cycle on and off like it should. When the freezer is cold, make sure the evaporator fan inside is also running. Get back to me on this and keep me updated on it, and tell me how dirty this coil was if it was. I will be checking to see if you have contacted me on this. It may be the thermostat, but I need to know the condition of the other sections. It could also have a small enough freon leak to cause the compressor to run, and run. If it gets low enough, it will short cycle on and off, you will know when it happens. Contact me by my user name below.
Sincerely,
Shastalaker7

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.

Runs -6far. for about 2 weeks, then alarm sounds, unit is warm.


its the problem of the motor which runs the fan.that motor needs replacement.a very chance it can be possible that the motor is perfect but the wirings from the motor which connects to the fan are faulty and got cut in between.but it can be possible.so first check out the wirings if they r perfect then its faulty fan  motor.get it replaced. thanks.

Kenmore Upright Freezer compressor running 6 seconds every minute


Usually the compressor runs pretty warm anyway. However if you think it's too hot I would start with the condenser coils located either under the unit or on occasion they are located on the back. The air flow across these coils as well as the airflow around the compressor must be maintained. I forgot to ask if the condenser fan is running. Check and make sure that the Fan is running and the air flow is good. Also, When you transported the unit did you move it standing vertically like it normally stands or did you lay it on its side. If you transported the unit on its side you must wait a minimum of 24 to 48 hours prior to start up or the unit could be ruined permanently. The refrigerant has to be utilized through the compressor as a gas. If the unit is on its side liquid refrigerant could be introduced into the compressor and can cause permanent damage. If this is the case I recommend that you turn the unit off at once and wait the 36 hours for the Refrigerant to settle then try it again. This transportation rule applies for any appliance That uses refrigerant, Air Conditioners etc. These units are not that hard to diagnose. The only other item that is usually a problem is the defrost timer. It is not very expensive and can also cause some of the same symptoms that you are eluding to. The defrost timer allows the freezer to periodically shut down to prevent the buildup of frost or ice on he evaporator coils and on the inside the unit. If it is defective, then the unit will either run all the time and cause the evaporator coils to freeze up or will not allow the compressor to switch on and it will not freeze like it should.
