The above will take you to the installation manual for your unit. This is to make sure you have set up the unit to their specs.

There are multiple things that can cause a lack of cooling. Let's cover a few of them.

1: Make sure the condenser coil under the unit is clean. You have to be able to take a flashlight and see light through the coil and fins. Be sure unit is off when cleaning. Use vacuum, compressed air, or a long, stiff bristle brush and go with the fins direction so they do not bend over.

2: The termostat may be set wrong or is not working as designed. Look for the compressor and fan on the condenser to cycle off when temp is met and on when it gets too warm. If unit is running all the time, look for frozen up evap.

3: If evap is frozen up, no air can pass through so no cooling is taking place. Air can not go through a solid block of ice. Clear ice with warm water. Again, make sure unit is off first.

4: Door not sealing or closing all the way. Seal on door should have magnets that help seal them to the door frame.

5: Again, if unit is running all the time, as in #2 above, unit may be low on refrigerant (freon). If you suspect this to be the case, have a qualified tech do the repair. Make sure he locates and repairs the leak. Adding freon without the repair means he will be back to do it a second time. The system is a sealed one and you should not have to continually add freon.

Good Luck and hope this get you going.

Unplug the unit & remove the plate holding the thermostat. The capillary for the thermostat will go into a very small tube that runs into the evaporator coil. You will probably not be able to see the tube but will have to feel for it and get a good orientation for where it is located before you pull the capillary out. Try to measure the amount of capillary in the tube as you pull it out so you know how far you have to push the new one in and put some kind of tape or mark on the new capillary before you try to push it in. you might have to soap up the capillary to get it to slide easier.

should not be on all the time only when it is cooling.. make sure your fan and blades and condensor are clean this will make your fridg cool better and run less should be cleaned at leaste once a year.....
