Hello,

This is intended as a guide to defrosting a refrigerator. Side by sides and bottom freezers may be similar but will require some different procedures to remove covers to get at the defrost coils.

If your refrigerator is not cooling but your freezer is still working then you most likely have a problem with Ice buildup. Sometimes the ice will start to form inside the refrigerator on the bottom of the freezer compartment, even though the refrigerator section is not staying cool.

1. Empty out the freezer section so that you can remove the bottom panel that covers the evaporator coils. Side by side refrigerators often have the access panel in the back of the freezer.
2. Use a hair dryer or fan to speed up the melting of the ice. Towels will be needed to soak up the water. A wet/dry shop vac and a hair dryer work the best. Melt with one and collect the water with the other.
3. Take the couple of screws that hold the defrost coil loose and remove the heater. With an Ohm meter check the resistance of the coil. If the coil is bad you will get either and open or shorted circuit. If you get a good consistent resistance then it is okay.
4. If your heater coil is good and the fan/blower is working then you probably need to replace the defrost timer or advanced defrost control board, whichever is in your unit.


Replace all pieces and wires to their original positions and then restart the refrigerator. It may take a bit for everything to cool back down, especially in warm weather. Now with everything working properly you should be trouble free again.

Good luck

The Sub Zero bottom dram freezer has stopped working


HI,
What does you freezer do? Does the lights work and fan work? The fan works with the cold control, if the light switch fails the unit will defrost in about 3 - 4 hours, will remain cold though, just not frozen. I need more information to direct you correctly.

Sounds like a defrost problem. Check to see if there is any frost buildup in the back wall of the freezer. If so, it is not defrosting as it should.
  • possible causes:
  1. bad defrost timer
  2. bad defrost heater (in freezer)
  3. bad thermo switch in freezer
If you don’t know what these are then unplug the machine and let the ice melt in the freezer overnight with the door open. Then try it the next day, if is cooling fine then you need to have a service person replace one of the above items.
