Vacuum condenser keeps flashing - Sub-Zero 650 / O Bottom Freezer Refrigerator

Usually vacuum condenser light is on, not because of condenser coils dirty, but low on refrigerant unit, so compressor is running longer then usually. You can shut your subzero off at breaker box, if light will keep coming on in day or two, you will need to call service to replace evaporator. Most likely evaporator in Fresh food section has leak(at list its most common place). Check this video I made, even if Your Sub Zero sideXside it still will look the same about changing evaporator. Hope that was helpful.

have you check the condensing unit it could be in need of cleaning depending how old is the unit.also check the fan blades for excessive dirt wich will decrease the rpm o the fan motor.

MOST LIKELY FRIDGE SECTION IS LOW ON FREON! "VACUUM CONDENSER" WILL COME ON IF COMPRESSOR RUNS MORE THAN IT SHOULD BE. COMMON THING IS LEAKING EVAPORATOR COILS IN FRESH FOOD SECTION. CHECK MY VIDEO, I HOPE IT HELPS.

The condenser is the 'radiator' located under the unit near the compressor. If it's clogged it will cause this. Make sure, also, that the fan at the condenser is operating.

If you've not yet cleaned the condenser, do so with a vacuum both sucking, and then blowing, to clean it well. BE READY FOR A DUSTY MESS!!

From the manual:

The Control Center monitors refrigerator and

freezer temperatures as well as the ice maker

system. If there is a temperature or ice maker

problem, you'll be alerted by a flashing

SERVICE indicator light. This same SERVICE

light will also flash if the condenser needs

cleaning. Before calling for service, please

check and see if your condenser area needs

cleaning. Refer to Condenser Cleaning,
page 22.

CONDENSER CLEANING

In all Built-In models, the condenser is located

behind the grille. First, remove the grille. Then

using a soft bristle brush, vacuum to remove

dust and lint from the condenser. NOTE: To

avoid bending the condenser fins, be sure to

vacuum in the direction of the fins (up and

down). Clean the condenser area every three

to six months.

CAUTION

Before cleaning the unit, shut the electricity

off at the control panel. When you

clean the condenser, wear gloves to avoid

injury from the sharp condenser fins.

Failure to clean the condenser could

result in temperature loss or mechanical
failure or damage.

It is telling you that you need to vacuum the condenser coil. if this fails to cure the warming problem then you my need a new condenser. compressors have also been know to cause this.

Good day,
Cleaning the condenser is what the correct term should be. To vacuum many times does a poor job. I use either a compressed air tank with a hose, or else a push-pull vacuum cleaner with the hose and a crevice tool attachment on the end to blow the condenser clean.

Can create a mess at the time, but the condenser will be clean, and the purpose is to protect the compressor.

The vacuum condenser indicator keeps flashing on and off. I did vacuum the unit, the the indicator lights keeps flashing on and off. How can I reset it and keep it off?
Thanks,
Rob

Your problem might be serious enough to warrant a repairman's visit. But this was my experience: An official Sub Zero repair company in NYC told me this: If the "vacumm condenser" light keeps flashing after you've opened and cleaned the condenser grill, then either pull out the plug for the Sub Zero refrigerator or turn off the circuit breaker (or fuse) in your house that leads to it, wait for some minutes and then turn back on. It is NOT enough to turn off the unit using its own internal on-off switch - it has to be totally disconnected from the AC. I did so, waited 15 minutes, turned back on, and it worked!! I had vacuumed the condenser grill twice but the "vacuum condenser" light kept flashing AND the refrig would go bonkers if set below 38. Now the flashing warning is off and it's down to 35. Great !!!

Turn the refrigerator off for a minute to reset the vaccum condenser light.
