Subzero door left open - now acting strange

Hi - My nanny left the door open on the subzero and when I came home I opened it and it is dark. I can see the temp and the bell, and can change those, but they do not light up anymore. The bottom freezers seem fine and the other side of the fridge is fine too (but it might actually be a seperate unit). Please if you have any advise - I hate to have my food spoil! Thanks!!!

Re: Subzero door left open - now acting strange

You have probably already figured this out, but if the door is left open there is a sensor that will turn the lights off to keep the fridge from overheating. After you close the door and let it sit with the lights off for 15 minutes or so, the sensor will cool and allow the lights back on. If the temperature reading in the window is ok and does not say "service" or "vacuum condenser", then you should have no more trouble.

Subzero freezer works refrigerator lights off and not cooling

You probably have a bad light's the one on the left up top. If you look closely you can still read the temperature in the display to tell if it's cooling.

How to remove bottom (freezer) door on my subzero refrigerator/freezer

With the door closed. Remove the cover over the bottom door hinge by removing the two screws holding it in place. This also allows the door closing mechanism to be removed. Rotate the door closer away from the refrigerator and slide straight down. Now open the freezer door. Take a pencil and mark around the hinge on top of the freezer door so you will know where to put the hinge back in place later. Remove the three large hinge screws and two small shipping screws. This will release the door on the top. Rotate the door away to get free from the hinge and pull the entire door straight up.

Undercounter subzero 245 refrigerator box not cooling yet ice maker working fine

Is the fan running? Has the door been left open? That unit has an automatic defrost and if the coil doesn't get cleared of frost it won't circulate air.

LCD panel and lights not working

On your Sub-Zero 642 Your display will not work unless your refrigerator lights work.
1st. Make sure your light bulbs are good.
2nd. Check your refrigerator door light switch.
3rd. The subzero uses a thermal overload to kill your lights if the door is left open to long.

Hello. My freezer part of my subzero 690 is getting too cold. The temperature has dropped to -8. My normal setting is zero. I tried raising the setting to +5 with no effect. I tried turning the whole...

check u tube for problem solving videos.

There are a number of great troubleshooting u tube videos, which show you what to look for and many of the fixes are really simple and are universal for all fridges. The simplest is that you left a door open, moisture got in and froze causing ice to build up, so you have to thaw it totally, not just turn it off. I moved my older subzero and think one of the tubes must have been knocked and it lost its Freon, so stopped cooling. The cost of having it recharged was so prohibitive (ie environmental disposal issue meant it had to be moved to a special location fixed and moved back at my expense or Subzero said it was a closed unit and you had to replace the whole thing$ 1,300 for the condenser alone) so, I tossed it + bought another used one until my renovation was done.

Generally with any fridge, there seems to be 2 possible Simple reasons:
1. DEFROST MODE PROBLEM it is stuck in defrost mode
. a)the defrosting tube is plugged

b)The tube or thermostat is frozen, most likely because someone left the door open or the seal is poor;

c) termostat defective-untube video explained how to test circuit;
4. CONDENSER ISSUES: the condenser coolant gas is low and can be easily recharged- see the u tube how to video;
5. Condenser is dirty and cannot breathe- vacuum it;
6. The condenser overheated and needs replacing . 4-6 will have the condenser blowing cool not warm air.

I have had this problem with the fridge portion of my SUBZERO bottom freezer and Subzero (and a repair person ) gave me some good advice, which should also apply to yours, but you might want to call them yourself:
1. Simplest fix- if the defrost tube is blocked or frozen, the defrost cycle will stick on preventing cooling (either freezing up or heating for the defrost cycle not cooling); Some subzero models are especially prone to this. I could see part of my tube inside the fridge on the back wall close to the bottom where it drains and removed the panels to expose and clean it;
2. You should pull it out and unplug it to get it to defrost fully. After doing that once, I made sure my fridge was on a separate circuit or switched!! Yours might not be the same, but on mine the tubes run through the fridge to get to the freezer so both parts have to defrost;
3. Subzero fridge and freezer each have their own independent condensers, so you might be hearing the condenser for the fridge running, even though one part is turned off.
4. Check the thermostat to see if it is working. There is a good u tube video on this.
5 Some of the u tube videos show how to "recharge" the Freon. Subzero told me these are sealed units and could not be done, so regardless of the problem, the condenser had to be replaced. The subzero repair person was really helpful + checked the Freon or gas level (Mine was old enough that it was Freon not the newer environmental stuff) so they would have to haul it away to drain and recharge it + then the condenser might still have to be replaced.

Good luck

SubZero 532 frig lights out

There are two door switches one for fan and the other for the lights. With the compressor running, there are two so yu need to make sure it is the refrigerator and not the freezer, open the door and press the right switch and listen for a fan. The left should be your light switch and the problem is generally in the switch, on rare occasions there is a failure of bi-metal safety switch part number 4200850. One very rare occasions you may have a wiring proble.If you go to there is a showroom locator tab on the top right corner, click it and you will go to a locator page which will get you to your local parts didtributor.

Subzero 650 not running

Check the light switch on the door frame, if that doesn't do the trick change the light bulb. If your refrigerator is not running and cooling and the light is out check the power, plug & circuit breaker in the power center.
