Subzero 700BR Refridgerated Drawers Not Cooling

Over a few days the drawers began warming up. First thought was to remove the kick plate and vacuum the fins. Found that they were totally covered in lint / dust. I vacuumed them and put the kick plate back. The compressor still works but the drawers are not cooling. I have turned the unit off, reset the cooling temperatures and still the same problem. Is there an "easy fix"? That is, before calling in an appliance repair person. Not sure if it may be the thermostat? Thanks

If your unit is new enough to have an on/off button on the keypad, then put it into diagnostic mode by pressing and holding the "colder" button, the pressing the on/off button at the same time. the display should change and it should read a temp like 67r or 67e. you can scroll back and forth through the 2 temp readings by pressing the colder key. If the fridge has been running, the temp of the one ending in "e" should be no more than 38. If it is, then you most likely are low on freon and will need to have the evaporater replaced. The part will be covered under the 12 year parts warranty, but the labor will only be covered for 5 years.(from date of install, not date of manufacture printed on the lable) If you want to go into it more, take the lower drawer out and remove the 6 screws holding the panel to the floor inside the fridge, then slide out the floor panel. Look at the coils in there, and if you see a ball of ice on the left hand side, you have a freon leak and the above repair is what youll need to to. if its older than 5 years, ecpect to pay about$500 to have it's a mojor pain. If its less than a year out of the 5 year, call subzero...theyll probably take care of it for you anyways. Good Luck!

Side by side freezer is 20-30 degrees. could problem be a gas leak in compressor ? how do you check the compressor without installing a port to check the freon ?

You cannot add refrigerant. Only an EPA Certified Technician can do this.
Most of the time the problem is a fault with the defrost causing the coils to Freeze up preventing cold air from properly circulating.
Also be sure the condenser is clean.

1) Pull the refrigerator away from the wall and unplug it. (If your refrigerator has front legs used to level the appliance, push these upward and set your refrigerator on its wheels before moving it.) Or, if it's a built-in model, turn off its circuit breaker.
2) Remove the cover panel to reveal the coils and cooling fins. On most models, the kick plate or top trim plate simply lifts off. You may have to remove a few screws to remove a back cover.
3) With a long, narrow nozzle on your vacuum, or a refrigerator coil brush-a special long- handled brush that looks somewhat like a bottlebrush-clean out all the dust and debris. Be careful not to bend or dent the cooling fins.
4) Replace the cover, and then plug the electrical cord back in or turn the circuit back on. Push the appliance back in place.

My DC17 animal vacuum makes a sound like a motorcycle running when the roller brush is lowered. I ran over a frayed rug and pulled all the yarn out of the roller brush. It still makes an awful noise. ...

I wonder if there is more yarn caught around the drive end of the brush?
Can you remove the floor plate cover, over this part of the vacuum, and make sure there is not more yarn wrapped around, out of sight from the outside?
If not-- maybe the bearings have been damaged by the great deal of yarn.

Remove the cover plate, and tell us what yo fins-

We can't find the model number on our old fridge we are trying to recycle and get a rebate.

Good day,
Look under the front kick plate (grille). You will have to remove it. If not there, look for an embossed plate inside the fresh food compartment. It may be covered by drawers, so you will have to look.
A general rule is it is located in a place that would not require you to move the machine, and it is never on a door, because they can be replaced.

My light says "vacuum condenser". I cleaned coils and fan and turned unit back on. Light came back on in few days, also don't know where reset switch is. Thanks

Good day,
The power off/on switch is the reset proceedure on most Sub Zero's however, it initially comes on when the unit senses the temperatures are too high, leaving the compressor.
It also is a known fact that a Sub Zero condenser cannot be cleaned by vacuuming only.
Service techs use either compressed air or nitrogen with a hose to blow the condenser clean.
Lacking that, a good push -pull shop vac with a crevice tool makes a good substitute.
Remove top grille, and the cover plate for the compressors.
Aggressively blow the condenser out from both sides.
Make sure it is clean, by shining a light on the inlet side, and making sure you can see thru the fins.
It's ugly, dirty and makes a real mess,
But the option long term, is winding up replacing the compressor(s).

Vacuum condenser light of sub zero 650 is on - how to clean it

We recommend vacuuming your condenser every 3 - 6 months. Cleaning the condenser is important for the overall operations of the unit including cooling functions. A dirty condenser may lead to warm temperatures in the refrigerator and freezer. It may also cause the unit to run excessively. It may contribute to condensation or frost inside of the compartments. If the condenser is not cleaned properly it may even cause premature failure of mechanical components in the unit. Condenser Cleaning - All Models Before cleaning the unit, shut the electricity off at the control panel. When you clean the condenser, wear gloves to avoid injury from the sharp condenser fins. Use a soft bristle brush and vacuum to remove dust and lint from the condenser. To avoid bending the condenser fins, be sure to vacuum in the direction of the fins, up and down. Clean the condenser every three to six months or sooner if you have pets. 600 Series Framed and Stainless Steel louvered grilles: First remove the grille screws located at the bottom of the grille. Tilt the top of the grille forward and release the springs from behind the grille, then lift off. Overlay Panel Grille: To remove, lift up then pull out at the bottom and down to release from its mounting bracket. Remove the two black screws in the lowest louver of the grille. Tilt the bottom of the grille out and away. It will release from the top of the grille. Model 601RG Stainless Steel Grille: Remove in a similar fashion as the overlay grille panel. 700 Series All Units: At the bottom of the unit, remove the four screws holding the kick plate/grille in place. It will then slide forward, giving you access to the condenser area. 400 Series 424/424FS At the bottom of the unit, remove the screws holding the kick plate. The condenser is located behind. 427/427R: Remove the four screws holding the kick plate/grille in place. It will then slide forward, giving you access to the condenser area. 430: First remove the screws located at the bottom of the grille. NOTE: These screws (Phillips head) are accessed with the door open. Tilt the top of the grille forward and release the springs from behind the grille, then lift off. 200 Series 245, 249, 315W Remove the kick plate at the bottom of the unit, giving you access to the condenser area.

Odor coming from back of fridge

This is very unusual, most of the time when I get complaints about odor it's form the inside of the cabinet. This should be easy enough to solve though. The odor is likely from dust accumulated underneath, or from something in the drain pan. If the unit has visible fiberglass insulation underneath you should replace it with new because, even if the source of the odor has been removed, the insulation can still contain it.
Unplug the refrigerator, take off the kick plate and rear cover. Clean and vacuum the entire under- carriage, condenser, fan, and condensation evaporator tray.
Be gentle with the components though, especially the capillary tube ( a pipe about the size of a 14 gauge copper wire )
