Question about Kenmore 74870 / 74873 Top Freezer Refrigerator

Kenmore 253.74970400 Refrigerator

Hi, I noticed the other day that the fridge was not turning off. So I took the cover off of the back of the inside portion of the freezer section and found that the coil was all frozen over and the opening where the cold air was suppose to be going down to the lower part of the fridge was completely blocked by ice. I cleaned the ice and the fridge started to work properly. My question is do you think that the Timer for automatic defrost is bad, or you think the Thermostat is bad? Or there is another part that is no good? Help Thanks

Yurkat, you want to make sure the defrost system is working. Bottom side of the controls you should see a hole where you can advance the defrost timer into defrost, turn clockwise until you hear a click. The calrod heater that sits under the evaporator should come on. If it doesn't, check the harnesses to both side of the heater and make sure they are in. If the heater still doesn't come on, you will have to test for voltage at the harness to the heater, should read 120V at the harness. If you have the voltage, it's the heater although I don't see too many of them fail. If you don't have the voltage the problem would be in the defrost terminator (bimetal) or the defrost timer itself. From what you were describing, evap frozen over and constant run, sounds like the thermostat could not be satisfied and therefor the constant running. Check out the pic of the bad bi-metal. back.

It is more likely to be the thermostat, it is very common on fridge freezers which only have 1 compresser. thermostat should be no more than 10-12 pounds from a spares outlet. they do universal stats so it would worth trying at that price. hope this helps

Issue with Kenmore Refrigerator/Freezer

ok,1st check on fridge side toward upper back of the top and feel for air coming thru, and there is another one down possibly behind crisper .I had this same deal. Had to do total defrost,, put food in cooler,, theres two blower fans in these types of fridges,,one in the bottom back,, and one in the back of the frezzer,, I used an old hair dryer and let it blow warm to top interior of frezzer,, careful not to let any cords hang/drop in any water!!,ok once done dry out as much water as possible, turn fridge on set both controls to 4,when fridge kicks on do the feel test,, you may need to close the frezzer door, air should be felt near top inside of fridge,if so than shut fridge side and feel inside frezzer near bottom and air should be felt,, side-by-side need to circulate air from frezzer to fridge, then back to frezzer

Kenmore 795.7731 Fridge warm;freezer cold - Error er dH

I faced the same problem for Kenmore elite Trio Model # 795.77543600 bottom freezer refrigerator. The issue as pointed out by Medeer on, turned out to be the part called component assembly, part number 6615JB2005H. I got this replaced yesterday but for 4 hours I did not notice any cooling... so I thought it did not work.... but then in the morning I notice that the issue has been resolved, the refrigerator is cold and there is no eR dH error message. Thanks to all who shared on this site.

Kenmore Elite Trio

How to remove the speaker from a Kenmore Elite Refrigerator. 
Our Kenmore Elite fridge has been beeping since we bought our house 9 months ago. There's nothing apparently wrong with it, the filters have been replaced etc. Sears said it would be a minimum of $300 to replace the electric panel (and my thought was that whatever is causing it could happen again!). We were ready to buy a new fridge.
Tools:  thin spatula or hand held flat razor (for scraping paint) flat screwdriver  soldering iron
I pried open the water dispenser with a razor thin spatula (i began with just my hands). the electronics then turned off. When the dispenser came completely off an electronic board dangled down. 
On the board is the word 'buzzer' with two soldered points, underneath was a round black object, obviously the speaker. My husband and decided that if we pried the speaker off with just a screw driver, it may break the whole board. So we got out the soldering iron and one at a time, heated both soldering points labeled "buzzer." As each heated we used the screwdriver to pry the speaker off the board. 
The speaker gently slipped off the board into our hands. We placed the board back in its place and snapped the water dispenser cover back into place. The whole thing took 2 minutes. The electronic lights all came back on the dispenser. Everything works perfectly. There's one less beep in our house!

Kenmore 596-76512 fridge not cooling freezer seems to be working still

If the fan above the evaporator coils in back of the cover isn't running then no cold air will be blown up to the fridge area. That's a common failure item and very easy to replace yourself. And by the way... $200 bucks and 2 weeks out is about normal these days believe it or not. It's what we would charge ya! :) At least you did the troubleshooting and saved yourself a couple hundred bucks.
