MY Subzero freezer door is also stuck shut .

Hi The repairman came today and said we should allow it to defrost and then open it. He wants about 500 to repair the drain assembly and something else. Yikes!

Anyone know anything about this problem?

This sounds a little high especially since the door can't be opened the check it out. I would call another appliance tech. First, unplug the Ref and let it defrost then plug it back in and send some more info on what it's doing before it gets so bad the door becomes stuck again.

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.

Clogged up icemaker on subzero 601F due to the door not being properly shut. Do I need to defrost the whole freezer to unclog or is there any other way?

You can buy a little steamer at the store and use it to defrost small areas. usually it's the fill tube that freezes, and you can hit just it with the handheld steamer. Lots of times however, this model will create a large ice flow below the glass shelf behind the upper basket and icemaker. this is usually caused by a bad drain trough heater. the only way to defrost this is to turn the unit off for 2 days and put towels down inside it and underneath it to catch the water as the ice melts.

Sub zero freezer drawer frozen shut

Subzero freezer: We had all our drawers stuck, including the ice drawer. We turned off the refrigerator, took all the drawers out and defrosted the rails with a hair dryer. The ice drawer was misaligned, so we reset the allen screws on the left to be the correct width. All better!

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

Ice is forming at the bottom of the freezer and freezing the bottom draw shut. it doesn't appear to be leaking and the door shuts properly. it's supposed to be a frost free freezer....

Causes:

High humidity in the immediate area causing condensation to freeze at the door opening

A frozen defrost drain line not allowing water to drain off when the unit is in defrost

A bad door gasket causing an air leak

Some freezers have a heated perimeter to reduce condensation. If the stop working, moisture can accumulate arounf the door perimeter and freeze.

Leaving the door open too long or something obstructing the door

Our Subzero 561 ( -15 yrs. old) just started making a rattling noise. It sounds like a fan is hitting ice. It stops when we open the freezer door. When we look up in there, ice is caked on. What steps...

Sounds like a defrost problem. Check to see if there is any frost buildup in the back wall of the freezer. If so, it is not defrosting as it should.
  • possible causes:
  1. bad defrost timer
  2. bad defrost heater (in freezer)
  3. bad thermo switch in freezer
If you don’t know what these are then unplug the machine and let the ice melt in the freezer overnight with the door open. Then try it the next day, if is cooling fine then you need to have a service person replace one of the above items.

Freezer Drawer Stuck

Our 550 bottom freezer drawer froze shut earlier this week and the motor made an unusual sound, like it was working too hard. Two of us eventually were able to open the drawer to find that it had frozen shut due to a leak which filled the ice tray solid and then adhered to the actual door, freezing it shut. We emptied the fridge and freezer, turned the control dials down to 0, but neither the motor nor the light would go off. We finally killed the circuit breaker to get the appliance to shut down. It's cleaned and defrosted and we noticed that the gasket has torn in three places, two on the fridge door and one on the freezer door. The freezer door could be from our tugging, but the refrigerator door is normal wear and tear. We filled the tears with some kind of putty and when it is dry we will start everything up again. This is not the first problem of this nature we have experienced with our subzero 550, but it is the most dramatic. Each previous time we have called a repair man out and he has been unable to fix it.
