Sub-Zero Repair Orange County

What to do when temperatures rise in your Sub-Zero Refrigerator?. Before calling for service, you can check some relatively simple things on your Sub-Zero.

• Examine the temperature settings for the compartment. On a display panel, 37°F is the proper setting for the fresh food compartment. For the freezer, the normal setting is 0°F. Older Sub-Zero Collections such as 200, 300, and 500 have dial controls. Set the dial between 4 and 6. One is warmest, and ten is coldest.
• Confirm the door closes and was not left ajar for a very long time. Turn the door alarm on to ensure the door is closing all the way.
• Remove anything from inside that is blocking the door from closing.
• Examine the door gasket or rubber for damages.
• Clear the condenser if you did not clean it within the last six months.

Note: If the temperature is above 48°F (set-point at 38°F), it's unlikely to recuperate from a condenser cleansing. Contact MD Appliance LLC to schedule service appointment.

• If the control panel is not on, confirm the unit is not in Sabbath Mode.
• Check if the lights are off and there's no cooling inside the fridge. However, if the freezer is working, as usual, be sure that you did not turn the refrigerator off.

If the fridge remains warm after these steps, it will need service. Contact MD Appliance LLC to schedule an appointment for repair.

There might be several reasons why your Sub-Zero ice maker is not making ice. The most common reasons are frozen ice maker tube, faulty ice maker, or faulty water inlet valve. Low water pressure or warm freezer temperature could be the reasons for low or no ice production. Water pressure should be either 20-100 psi or 35 - 120 psi, depending on the model. The recommended freezer temperature setting is 0°F. If the freezer temperature is higher than 15°F, the Sub-Zero ice maker will not produce ice. 

If your Sub-Zero refrigerator is continuously running or not cooling, it might be time to clean condenser coils. Suppose you want your Sub-Zero refrigerator to work efficiently and correctly for a long time. In that case, you should clean the condenser coils every 6-12 months or even more often if pets are present.

Please follow the condenser cleaning instructions:

• Before start cleaning, power down the unit via the control panel.
• Take the top or the bottom grille off to access the condenser.
• Use the soft brush vacuum cleaner attachment. Vacuum vertically to avoid bending condenser fins.
• After you've done, reinstall the grille back and power up the unit.

These are a few steps to troubleshoot the problem:

• Confirm the condenser is clean and free of dust.
• If possible, check the temperature inside both compartments. Suppose the temperature is higher than the normal set-pointed temperature for the compartment for a few days. Therefore that is the reason for excessive unit run.
• An overfilled compartment can reduce airflow circulation and cause the refrigerator to run excessively. Fridges and freezers work finest when they're 25-75% full.

Here's a brief listing of signs to look for on your Sub-Zero that might indicate a functional problem.

• Higher than the normal temperature inside any compartment is the right indicator that an issue exists.
• Any unusual noise, behavior, or temperature fluctuations.
• Constant extreme sweating or moisture on the inside of the fresh food compartment.
• Unusual quick food spoilage or freezer compartment not capable of freezing food.
• Ice or frost built-up inside the freezer compartment.

If you have seen any of these signs, particularly if they persist, contact MD Appliance LLC. We'll help determine the cause of the issues and correct them.
