I came home yesterday and noticed my wine refridgerator had a code in place of the temperature readout. The code was E3 and as I played with it also E4 came up. The temp on the lower portion read 75 degrees, and wasn't cooling. I pulled it out and didn't see any issues. Didn't see any reset button, unplugged it overnight, and had the same error this morning when i replugged it in. Any thoughts or advice?
E4 on danby designer wine cooler - TEST your compressor: Cooler can be forced to operate and cool as a test. Unplug unit from 115v receptacle. Hold both temperature control buttons down. Plug unit in 115v receptacle. The cooler should start, but the thermostat will not stop the compressor. Now you got a freezer ! I do not know how to fix the E4 error yet.
Is the compressor running? I don't know this unit, but know that if you are too warm that is the first thing to check. In reading about another unit that had a different problem, it was mentioned that there is a ciruit board. If it has relays on it then these are the most likely culprit. They are either not making contact or staying in contact too long... sometimes just tapping each relay usually a black plastic component will cause it to work intermittently..Not sure if you can get these but call the company help line at 1-800-263-2629.

Some dual temperature wine coolers build up frost in the rear and top of
the main compartment. Check the defrost timer, located either inside
the main compartment near the light, or outside on the back of the wine
cooler near the compressor. Look in the owner's manual for the correct
settings for the defrost timer and adjust yours as needed. Make sure
that you have the wine cooler in a spot where the outside temperature
remains at or near room temperature to reduce frost buildup.
I am sorry to hear regarding the trouble. This is a common problem on this unit. E4 refers to a faulty control board failure. Unplug the unit for few minutes, say 15 minutes and then turn it on. If this would not reset the error code, the only solution is to replace the board.
We had that problem in 2007, about 10 months after buying it from Costco. It was under warranty so the tech came and changed both sensors. It's worked fine until Feb 11. Now, the lower section ran so cold it froze some bottles. I am looking for a solution to that problem.
