overnight, 10 hours
History: for some time, the freezer has been short cycling, running in 5 second bursts sounding as if it wants to run but is never able to come on. However, the freezer stayed cold enough until a few days ago. Noticed ice melting. Turned freezer off overnight with door open. Refrig side lost it's coolness even though was not turned off. freezer now freezing but will not cycle. refrig is at 40* after running all night and day.
The coils are covered from top to bottom with a light frost.
just moved the thermometer from refrig to freezer. it is however, colder in freezer but still will not cycle and does not feel near 0. refrig is a 41
btw, the dial for the refrig is on 9, and the freezer is on 7. with 5 being the norm
I am not sure I clearly explained the sound I hear in the freezer. It is the fan I hear in short bursts. It may be the compressor that is trying to start up. I do not know. But, it is a constant burst after burst like someone is exhaling deeply over and over. It never stops doing this and it has operated like this for months. I never hear the compressor run for any period of time. Also, the unit was only unplugged for a few minutes while cleaning underneath. The dial was turned off to the freezer and the door left open. The refrig was left running during all of this.
Not ready for you to write me off yet. The unit sounds exactly as it has for months. WHEN I stick my head in the freezer I believe I hear a constant sound faintly which may be the compressor. But the fan definitely is operating in short bursts. How do I know if the compressor is bad or not? Also, could the massive amount of dust build up underneath have caused the thaw out in the freezer to begin with?
I removed the upper panel in the freezer and it is the fan motor not running correctly. thank you for your help.
I still need help with this problem. Do I need to ask a new question? or do I post it here?
the unit is getting cold enough. I replaced the fan motor inside the freezer but there is no change. The fan operates intermitantly. It acts as if it does not get consistence power. It never gets to full speed, or even half speed.
Please pardon the delay. I am rustling around picking kids up from school. As of last night, the compressor was warm. The fan next to it was running when I vacuumed out the coils down below. 30 minutes ago I heard the compressor come on and I watched as a frost began to form on the coils inside the freezer. There was no frost pryor. That reminded me that I had reset the temps to "5". Also, I had disconnected and removed the fan in the freezer last night. I will be back home in a few minutes.
Ok, I am in front of the unit. The coils are completely frosted over, the compressor is running, the compressor fan is running, the compressor is warm, not at all hot. temp in frig is 65
thankyou, I will try all of that
Tyler, One last question: Should there at any time be a heavy frost build up on the coils in the rear of the freezer? If the answer is no, then the problem has to be with the defrost thermostat. The man at the parts supply house talked me out of buying the parts, saying that it must be a wiring problem if there is no build up of ice on the coils. And, if the fan was running at all then the problem couldn't be the ADC board. I just returned home to find a large amount of frost on the coils. It may had been there before but thawed mostly before I saw it. Thoughts?
thank you. Back to the parts store I will go.
I realize this is early on a Sunday morning, so don't feel rushed to respond. I have another question about my unit. I replaced the ADC, which included a new wiring harness, and the fan motor (because I accidentally pulled out the connectors from the motor). The unit has been working well, freezer slightly below 0. However, the unit runs constantly. I think I might have positioned the refrig thermostat sensor incorrectly. I am wondering if this might cause the unit to continually run? How should the thermostat sensor be positioned?
Thanks, I will check after church
Back at the unit again. It seemed to run too much so I kept unplugging it at night so the compressor wouldn't run all night. I plugged it in yesterday and let it run. This morning all of the temps were good. Freezer was at 0*. I checked the compressor and it was not running and warm, not hot. an in freezer was not running. Opened the door for a couple of minutes and compressor kicked on and fan in freezer kicked on. Everything appears to be working well. However, I did notice a few minutes ago while trying to adjust the water filter connection so that the filter will stop getting pushed out of connection, that the fans were running but the motorized control door in the top of the frig was closed, not allow air into frig. I would have thought it would be open since the frig front door had been open for 10 minutes. could this be a problem? I replaced the wiring harness when I replaced the ADC. Not at all sure how the frig thermostat should be located behind panel.
Last thing, can you tell me how to place the thermostat probe inside the frig, around the "flap" or against the foam between freezer and frig, or how. Where does it go?
Thank you for all of your help. Everything should be great now. Attachments are only available to registered users.Register Here

Tyler, I still have problems. I don't know how the compensation works for you when a problem persists and is not easily resolved. Do I need to start over?
1) replaced ADC and evaporator fan
2) unit appeared to be continually running, both the evaporator fan, compressor and compressor cooling fan. Freezer temp stayed at 0*, frig at 35*. Both settings were on "5".
3) yesterday I took the panel apart in the upper left section of frig to adjust the thermostat bulb. I had previously wedged it in between the foam of the damper and the side of the frig/freezer. I wrapped it around the damper housing, inside the wire housing panel. I also opened up the evaporator panel inside the freezer to make sure it wasn't frozen up. There was a little frost but appeared to be correct.
4) thought everything was fixed. Although I had heard and seen the unit (compressor and evaporator fan) shut off and come back on, I was still skeptical about the unit running constantly.
5) yesterday afternoon my wife heard a loud "clanking" noise. When I went to check a couple of hours later, the freezer was at 31*. I moved unit out to check compressor and heard a clanking noise. The compressor was fairly warm but I would not say "hot". The freezer is still at 31* this morning. The unit still seems to run constantly.
Let's assume for a moment that the conditions remained as they did for several days with the temp constantly at 0*in freezer and 30* in frig. However, the unit ran constantly without shutting off. What would be the most likely cause?
The position of the thermostat bulb is something I have been asking for a week. Then I believe I may have worn out the compressor because of the thermostat bulb being in the wrong place. Where does it go?Do you have a diagram, drawing, instruction or anything?
Oops! I typed that wrong, the frig never got below freezing. It was within "REF" range on my thermometer. It is still within range. The freezer is on the edge of the "FREEZE" range.
WHERE I AM NOW-
My thought is clearly, if the temps were both in range (freezer stayed a little too cold at 0*), evaporator never froze up. However, the unit ran constantly, what would be the cause?
