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


i know this is late but there's a heater kit made for this 4202160 is part number,you remove the shelves,you can put a mark under the shelf arm on the far outside where the shelves hook on so you can put them back in the same spot,then remove the light cover,the two screws and metal cover and then pull the wall off and set it to the side ,the drain heater kit plugs into the wire harness,the heater will heat up and keep drain from freezing,you can slide the tube off,stick a screw driver in to hold it down to the floor so you don't burn your hand and blow hot air into it with hair dryer to melt out ice,keep heat on for like 20 to 30 seconds then cold air or remove heat you don't want to mess the hose up from overheating wait a bit and hit it again until you melt out the ice,then i use a long plastic wire tie to stick into drain hose to clean it out,some nasty stuff in there,i use a steamer to clean the line out and then i have a piece of 1/4 inch plastic water line to snake into the drain,if this is the first time this has happened you don't need the heater kit,just clean out the tube and metal drain trough,also clean the back of the top crisper drawer shelf,crumbs and stuff can get in between the back wall and the top shelf and then will fall into the drain,if you keep that area clean you won't have to many issues and keep the fridge a little warmer so it doesn't freeze up the water in the drain tube,put the drain tube back onto the trough and pour hot water into it,if it drains down you're done if it's still blocked get a turkey baster and push hot water down into the drain tube to clear it,if it still doesn't clear remove the bottom kick panel,you'll see the drain pan and look at it because you have to get it back the same way in the clips then you can see the drain tube,stick a plastic tie up in there to clean it,sometimes there could be dust or something in the drain pan,when the water hits it it can get into the bottom of tube and block it but i've only had to do that once,hope this helps you out.

the fridge will most likely reset it self , pull the cord from the wall and wait for a hour or so and plug it back in , it should kid back up .

this subzero freezer compartment did not free, but stayed cool. The problem was that defrost limit switch went bad, so when it was going to defrost cycle heater never came on, so it builded up snow and ice on evaporator coils and air stopped circulate. I replaced that little thermostat, and melted down ice.

remove all the drawers and unscrew the frame that holds the drawers. Free the the drain tube (need to unscrew the clamps that hold the tube to the back wall). Pull it up from the bottom hole where it drains into the pan and free it from the top drain pan. Most likely it's plugged with **** and fungus and yecchy stuff. Clean it out and reinstall it.

Need a model. Newer units have an on/off on the control.

It's a big door. You should check the refr drain. If that's blocked it will be harder to open than normal.

Just frost or a puddle? If it's a puddle cause by melting frost with no where to go then you had my problem. A clogged drain. First defrost the drain, a hair dryer works well, blow or snake it out then install the factory drain heater fix. Plugs right in and works like a charm. I've had my sub zero 550 for more years than I can remember. I'd buy another one in a minute. Good luck!

yeah vacuuming behind the fridge is a good start this will help the fridge preform better as when dust builds up on the condenser it will cause the discharge to be hotter than it should be making the cooling in the case not as efficient. i would start by removing the pannel in the fridge and seeing if any ice is on the evaporator

Most likely would be a failed defrost heater. Call an authorized servicer.

HI,

Is this on the 315I unit? The only way is to remove the cabinet, not easy but very possible and time consuming. If you have never done this, I would seek assistance by calling someone out. This job takes less than 2 hours to complete assuming there is no other issue with this unit at the time of service.

I hope this helps.

This job is difficult to walk someone through on the computer and the phone. No simple access.

I’m happy to help further over the phone at https://www.6ya.com/expert/gere_bf68e6055dd61249
