DIY Tips For Your Sub-Zero Refrigerator

As the very first company to produce standalone freezers more than 70 years ago, Sub-Zero is a name that goes together with guaranteed assurance and reliability.

Today, Sub-Zero provides appliances much more than just freezers, including refrigerators, wine coolers, and extended lineups of built-in refrigerators, which are sure to look stunning in almost any home.

But as one of the leading names in refrigeration appliances, it’s not surprising that homeowners get upset when their Sub-Zero appliances malfunction or stop working entirely.

NOTE:  WE DO NOT RECOMMEND TRYING TO REPAIR YOUR SUB-ZERO REFRIGERATOR AT HOME. TAKE THE NECESSARY PRECAUTIONS AND CONSULT WITH LOCAL SUB-ZERO SPECIALISTS BEFORE PERFORMING ANY REPAIRS.

Most Sub-Zero refrigerator problems are relatively simple to fix at the household using just a few basic tools.
So if you’re having difficulty with your Sub-Zero refrigerator, make sure to check out the following DIY tips to help you solve your problem.

Condenser Coil Issues

All refrigerators have condenser coils, typically located either at the back of the unit or across the lower part.

These coils are what your refrigerator uses to condensate and cool its refrigerant. So when the coils become blocked with dust and dirt, they become unable to release heat sufficiently. And in turn, this can cause your refrigerator to overheat and not chill down thoroughly.

So if you’re undergoing an issue with a Sub-Zero refrigerator that doesn’t seem to be freezing correctly, the problem could be on the dirty condenser coils.

To resolve this, start by unplugging the refrigerator and allowing the coils to cool down. Then, use a vacuum to clear any dust and dirt, then wipe down the coils with a cloth and warm water.

Once this is done, plug the unit back in and see if it has solved your dilemma.

If not, the problem might be in the condenser pump or the unit’s interior circulation fan.

So if you still can’t find the cause of your problem, give us a call. We’d be happy to stop by and diagnose and solve the problem.

Leaking Sub-Zero Refrigerator

Walking into your kitchen to find leakage on the floor can be alarming. However, a leaking refrigerator is usually a quite easy problem to fix and is typically reasoned by either a worn-out gasket of the door, a faulty drain pan, or a defective water valve.

Your fridge’s door gasket needs to form an airproof seal. Otherwise, you’re likely to experience internal sweating, which could be the reason for your water leak. So it’s the first thing to check the door gasket. 

Inspect your refrigerator door gasket visually to make out if it looks worn out or dirty. If it is dirty, try cleaning with a decision of water and soap, and then apply a thin layer of petroleum to the pad. That way, it will form a better seal when the door is shut. On the other hand, if the door gasket is old and pretty worn out, it should be replaced. 

The next common reason for a leaky refrigerator is a broken or overfilled drain pan. To check this, look under your fridge to see if the drain pan is full. If so, shake it out and inspect it for any damage at the same time.

Lastly, if your Sub Zero refrigerator has a built-in ice maker or water dispenser, you got to need to check that this isn’t where your leak is coming from.

If you can determine exactly where the leak is coming from, you can repair or replace the component yourself. But if not, don’t wait and give us a call, we’re always here to help.

Noisy Sub-Zero Refrigerator

If you’re living with an older unit, it’s not unusual to make some noise during its regular operation. However, if your refrigerator doesn’t usually cause any sound, and you’ve recently started hearing that it’s louder than ordinary, you might have an issue there.
The most common reason for a noisy fridge is that the unit is not standing correctly, which might be making the internal fan rub against its body. So check that your refrigerator is set to the right level.
We recommend that you level your refrigerator so that the door closes on its own from half-open. For this, use a spanner to turn the fridge’s legs and regulate its level.
Finally, if you have an old fridge that makes a lot of noises, and if the unit being off-level doesn’t cause the obstacle, another simple option is to get a soundproofing mat and set it under your Sub Zero refrigerator.
This should help to absorb the vibration coming from the unit and, in turn, give a much calmer operation.
