If you notice ice developing on the refrigerator door or the door seal, the seal may be faulty. When room temperature air gets in, the refrigerator will have a problem keeping the right pressure and temperature.

Condenser Dirty or Worn

The condenser may be unclean or worn. In case, the refrigerant will not cycle rightly, which will lead to over-freezing.

Sub Zero refrigerators have the function of a defrosting cycle when the refrigerator gets rid of additional frost and moisture through the defrosting drain. If the defrosting drain is dirty or clogged, ice will begin to form.

Sub Zero Refrigerator Temperature Fluctuates

Products in the refrigerator can influence the temperature of the fridge. Adding new once will raise the temperature, and packing the food tight will not allow the needed air to circulate to maintain the proper temperature.

Sub Zero Refrigerator Won’t Turn On

If you have recently relocated your refrigerator, you could be struggling with it not turning on. Remember, there’s lubrication in your fridge that requires staying in the compressor. If you didn’t keep it upright during the move, the lubricant could have leaked into the coils. The refrigerator needs to sit for a while after moving. This allows the lubricant to drain back to where it’s supposed to be. You can then turn it on, and it should operate smoothly. 

Check the unit door or drawer was not left open for an extended time, make sure the light switch is operational and check to see if the unit is not in Sabbath mode.

Make sure the power cord is safely plugged into the electrical outlet, and the electrical outlet has power. Turn the circuit breaker off for ten seconds then turn it back on. Also, make sure the unit is not connected to a GFCI.

Are you still struggling to solve the issue? If so, it’s time to call a Sub Zero repair professional.

Stop the Additional Frost in the Freezer

Older refrigerators are likely to have the problem of excess frost accumulating in the freezer. It’s typically a result of warm water getting in the fridge. Check and replace the seal around the door.
