You are so great….. I must admit I feel a bit overwhelmed to fix this, and at one point do I give it up? If I turn off the ice maker will that help? I love this refridge, and we cant afford a new one…… we got all the ice out of the back (at least 4-6 inches wide, all across the back) the crisper door would not slide all the way in. I don’t know anyone who could fix this in the Portland oregon area…. I think someone I paid tried all the wrong ways… but you are a gift. Thank you for your time!
very informative, thanks for making these. I have a model 500 and will be looking at more of these to keep her going. What a terrific machine but everything has its day!
One last question, you denoted the "Capillary Tube" for older model. What is that? Could you describe it? in the 550 the drain tube is dead center of the back wall. Perhaps you know where the Capillary Tube is in reference to center? Really greatly appreciated the video and help!!
Once you get a little ice in that area it’s all over. It just keeps accumulating until something freezes closed. Great video. Very interesting. Does that heater work on the 700 series also?
Hi. I'm not a tech, but I have a Sub-Zero 550 and ice is forming on the back and bottom behind the crispers. I ordered the 4201290 drain heater and when it arrived I not only realized that one was already installed but I also had one in my parts inventory box. So, I haven't changed out the existing one, because it seems that these parts shouldn't fail. Do you have any other suggestions to stop the ice buildup. The fridge door gasket seems fine to me. Thanks a lot and I love your channel.
You can test the drain heater by pulling it out of the drain tube and holding it in your hand while you press the fan button in, if it’s good it will get warm to the touch. The drain heater is powered by the fan circuit.
@@SubZeroSpecialists I couldn't pull it out even though I squirted hot water into the drain to melt any ice residue. Would it be a problem is I just continue to use my hand steamer to melt the ice and live with it? Thanks
There’s also a plate heater the goes on the refrigerator compartment floor to stop ice build up Lon the back of the refrigerator. I believe it connects to the fan motor
@SubZeroSpecialists thanks so much have an old 550 of a customer that is icing up constantly at drain. Old capillary thermostat. I will be replacing that part too.
Excellent instructional vid. Just did this last weekend. I now suspect I need to reseal my trough, too. Thanks for your channel!!
Glad to see something new I always enjoy watching Your repair videos.
Thank you

@@bonnieknopf8706 it’s an easy fix. Follow the video on my channel and if you have a problem reach out to me.

It is part number SubZero 4201290 that you installed. Correct?
Yes

The cap tube is the feeler bulb for the thermostat so it needs to be at least 4” from the braided heater that snakes through the coil
So the drain heater braided wire cannot be closer than 4" from the cap bulb?
I have a 550, would it be the same part number? Could you list the part number?
Are you looking for the part number for the drain heater
@@SubZeroSpecialistsyes, is it the same?

No that heater won’t fit in the drain, but we have other remedies.
With the 550, do you relocate the bulb bracket vecause from factory the bulb bracket is directly behind the tube. Thanks!
Yes, move the thermostat tube at lest 4” away from the heater
Thanks for the video. I am having this same issue. Can you confirm that for the Subzero 550 the part number for the heater assembly is 4201290?
Yes
I need some videos on 700 2 ice maker. What are those plastic things coming off the bottom and front?
They are part of the leveling arm that senses the level of cubes.
Exelent video! Do you have a part number? Or can you sell me the part?

Is the ice in the drain trough or on the floor under the crispers?

@@SubZeroSpecialists On the floor where it meets the back wall under the crispers.
You’re gonna need a floor heater
@@SubZeroSpecialists I couldn't pull it out even though I squirted hot water into the drain to melt any ice residue. Would it be a problem is I just continue to use my hand steamer to melt the ice and live with it? Thanks
There’s also a plate heater the goes on the refrigerator compartment floor to stop ice build up Lon the back of the refrigerator. I believe it connects to the fan motor
Yes that’s called a floor heater
@@SubZeroSpecialists I was just looking at that part. Is it worth the extra money? Almost $200
@@123HomerJ if you’re having a problem with ice build up on the refrigerator floor then a floor heater should eliminate the problem.
@@SubZeroSpecialistsCan you just have the drain heater? I believe the overflowing clogged drain is the issue causing that ice on the floor
@@amit.tyagi.officialcareerm3338 not sure what you’re asking, reframe the question
whats the part number of the heather kit?
4201290
@SubZeroSpecialists thanks so much have an old 550 of a customer that is icing up constantly at drain.
Old capillary thermostat.
I will be replacing that part too.
This way for 650/s models too
