Question about Sub-Zero Refrigerators
Thanks for using FixYa. Error code EC 24 means Defrost Under-heat. This error code means a fault in defrost system or freezer, but it is usually a false one. The control board on this vintage model didn't have the correct error code to report so it came up with the last code it knew.
You can try and reset the code by pressing and holding bell on/off key for 15 seconds. Also check if the condenser is plugged with dust bunnies.
Please do accept the solution if the issue is resolved or else revert for further assistance.

Tips for a great answer:
Your Refrig/freezer should be set as follows:
Refrigerators: 36 to 40 degrees. Ideal temp is 37 Fahrenheit. Note: A temp above 42 degrees promotes bacteria.
Freezer: temp should be -5 to 6 degrees Fahrenheit. Ideal temp is 0 degrees.
Then check the door seals around the edges to see if any splits, tears or cracks have messed up the seal. This will cause your compressor to constantly run as it's trying to cool off the warm house is being sucked into the freezer (or Refrig). A sure sign the door seals are damaged is lots of ice in the freezer door area or water pooling in the bottom area of the refrigerator.
Wait about 4 hrs after you readjusted the Refrigerator/Freezer settings so everything settles down. If you still have problems then the coolant may need to be serviced (topped off) or the motor serviced/checked.
Don't procrastinate because a water heater and Refrig/freezer are the 2 largest energy users in your home- they run 24 hrs a day.
Hope this helps...
