    Default Don't See SubZero listed, But have Subzero 700TR, cooling in top, warm in bottom area

    Model Number: Subzero 700tr
    Brand: Sub Zero
    Age: 6-10 years

    Refrig is cold in top section, warm in bottom drawers.


    I see the fan working which blows cold to the bottom. With the top drawer out, you can bring on the fan by pushing in the bottom drawer only! Guessing it should not work that way.


    There are two sets of drawer switches. One pair for each drawer. Somehow one of the switches for the top drawer is frozen with ice, and peaking behind the back panel, I can see ice built up beside that one switch. I imagine we need to get that one working. What would have cased ice right there only= and no where else?


    Once if get that working, I', guessing I need to see baffles open and close - if I can get to them.


    Are the baffles which control the top/bottom air flow, accessible through the top section with the big door, or through the bottom section with the drawers?


    I see 4 screws which appear to hold in the back panel behind the two drawers plus a few screws at the top, near the fan. I've removed all of them, but the back panel won't come out. It is loose at the top and on the right, but something is holding it?

    Any tips are much appreciated.

    Does anyone know the effect of the upper pair of drawer switches on cooling in the drawer section?

    Have not worked on one of these for a while...The fan circulates the air from the bottom to the top...... We will start at the evaporator coils , located in the evap. sump... Remove the bottom drawer and remove the four or five screws holding the sump cover...remove the cover...You should see the evap coils.....Are the coils " fully frosted "??? If the coil;s are full frosted there could be a restriction in the air ducts...The fan in the sump moves the air thru the coils and up thru the rear panel.....Each drawer has it's own switch...Open drawer, fan stops. Close drawer fan starts.............. If ice is forming on the switches it could be moisture/condensation coming from somewhere.........I would look at the door gaskets, are they in good shape??? no tears or gaps???........... Cannot find my service manual for this series.... What is the temp of the drawers?? ..fresh food section?? Can you post a picture of the evaporator after it has been running for at least an hour???...Have you removed the panel on the front and vacuumed the condenser coils ???

    Smile subzero 700tr

    ok...thanks for responding. I feel like I have been in the Saraha Desert..starving for (water) info on this unit!

    I have the unit working for now. The frozen drawer switch was keeping the lower section from cooling......but the service light will not clear, so I do not think I am out of the woods yet.

    I have thoroughly cleaned the condenser coil.

    This puppy has 2 sets of evap coils. It is refrig at the top and 2 lower refrig doors. You can read the actual evap temps on the display by pressing some buttons. Both the upper and lower show about 30 degrees and can hold set temps for the refrig areas at 38, at least for now.

    I'll be at the house in a week or so and can take some pics. One of my problems is that I could never get the back panel off which is behind the drawers. I could get the right side loose, but I never could free up and remove the left side. All you see there is 4 screws, and that's kind of frustrating.

    My understanding is that the service light comes on, whenever the unit senses that the compressor has run too long. You can reset the light but it comes back on. It seems the unit runs most or all the time. I think I read somewhere in the links below that by pressing buttons, the unit will display the hours it has run etc! Have not tried that yet.

    If you lost your manual, I can help. All of the manuals are available online for free at this site! New York and New Jersey Sub Zero Repair and Service | Aaron's Refrigeration CO. There you can view the parts, diagnostics, components, electronics, you name it!

    I did find a bad place in the lower drawer seal and that could have cause the ice on the evap coil which was right next to the ice build up on the drawer switch. I've fixed the seal, and don;t know if we are still getting ice build up or not. Can check this next week too.

    Last, Mr. quik-fixit, could you kindly send me a direct email to me at etbrown4 (you know the symbol) juno.com I think we might do better if we can just email back and forth, if that works for you.

    Many thanks for any tips you might pick up from the electronic manuals...esp how to remove the back panel of the lower section, as described the components section!

    Default SubZero 700 Series

    I've worked on quite a few Sub Zero's (Thought you knew that, Jake) One of my accounts here in Salt Lake, the Road Home, has eleven 500 and 600 Series Sub Zero's. Appliance Parts Company and Reliable Parts stopped selling the parts because of the Wolf merger or whatever they did. Anyways etbrown4, here is your parts and service manual you wanted for the 700 series including the 700TR

    edbrown4...could you recheck the model number again??? A 700TR has one evaporator coil............A 700-2TR has two evap coils..... did a Sub-O. 561 this morning and then to a home with a 700BFI and a 700BR ( under counter version of a 700tr ) ... so when you said that you had TWO evap. coils I was wondering ..... We will keep the missives to the forum in case another more enlightened tech. has better/ correct answers...... The panel could be stuck with ice, ( the proverbial ice ball at the cap tube to evap coil ) .... keep us posted........( I am never wrong, I just may not always be right ).....

    Default It is a 700TR For Sure With 2 Evap coils, Refrig Up and Refrig Drawers down

    Ok it's a 700 TR for sure!

    Looking at Aaron's site, Subzero Specialists (link) New York and New Jersey Sub Zero Repair and Service | Aaron's Refrigeration CO they call it a 700-3 or tall unit. Also known as 700TR.

    If you look at the component breakdown on their site (really just a bunch of Subzero pdf files) that seemed to picture the lower evap coil. On page 7-14 of the SZ Component Access/Removal manual.

    So can we agree that we're on the same page?

    I guess we can go from there, and figure out the eternally lighted service light. Thanks.

    Default 700TR Tall

    If we're in agreement on the model that's giving me the error code, can we commence to trouble shoot, like figuring out how to get the lower inside back cover off of the lower evap coil so we can see what's icing, if anything.

    Is it normal for a refrig evap coil to ice up say over 50% of its face area or so between defrosting cycles?
