20 Most Recent Sub-Zero 700TC Bottom Freezer Refrigerator Questions & Answers

I do not have your exact model, but I had this problem. There is a timer that periodically defrosts the freezer. For me it was near the compressor unit at the top and super accessible. When the timer stops working the fins in the cooler in the freezer become a block of ice and starts to do a bad job keeping things frozen. But it becomes noticeable when the ice maker stops as well for some reason. I learned it is super easy to replace the timer after a repairman estimated three ours of labor and was done in literally 20 minutes including cleanup.

Evaporator fan motor needs replacing.

The drain tube under the evaporator in the fridge is clogged. these can only be accessed by removing all the shelves and the light diffuser, then removing the back wall. even then, the hole is tiny and hard to put anything down into to clear the debris. I usually use a steamer to force steam down through to clear out the clog or ice. I get theses hand held steamers at walgreens for about $25. Might be cheaper than a service call to invest in one. Hope this helps.

The valve has a screw on top that you can remove, but it's very difficult to reach without first removing the lower tray that contains the compressor and condenser. if you remove the screw on the left and the screw on the right that are in at about a 45 degree angle, the whole tray will slide out. Be very careful though, as doing this is stretching the Freon lines and they may kink or they may kink when pushing the tray back in. once you slide it out a little ways, there is a screw at the top of the valve, and you may have to pull the wire off the valve to pull it out far enough to remove the quick release coupler on the water line going up to the icemaker. Be sure to turn off the water to the unit or the house water first!

How are the ice cubes? Are they normal size or hollow? I was wondering if some of the water was not making it into the ice maker and causing this issue. Is there any frosting issue not mentioned? Any water droplets on or around the back wall of the unit (inside)? I am a service tech certified and would like to know more about this issue. Have you cleared the drain completely, meaning after you de-iced unit, did you use water to verify the drain was cleared?

I you like to know more, so I can direct you in solving this issue.

hi i have the 700tc as well,,ok the best way to place the drawer,,,extend the 2 sliders all the way out,,there is one pin at the end of each slider and 1 hole on each side of the drawer lip which lays on the track ,,,the holes on the drawer must fall into the pins otherwise it will not close,,,so place the drawer on top of the slider ,,,what usually happens is the sliders tend to roll back into the housing of the fridge,,,so while the drawer is resting on the sliders reach under the lip of the drawer and pull each slider until the the holes of the drawer falls into the pins,,,when the drawer is seated in the pins it will close smooth,,,hope this helps
