I have a Kenmore commercial freezer - I can't find the cubic size, but it is huge! The alarm went off, we pushed the reset button, but it won't go back to the correct temperature (10 degrees). It will go to 21 degrees, but flashes a "6".

It is uaually coded into the model #. Usually in the middle. I can usually eyeball them. another solution is measure the outside dimensions of a refrigerator or freezer you know the size of then compare them. This will give you a rough estimate.

Sounds like the temp sensor is bad or intermittant. Check the connections to the display to see if they are loose. If not, the sensor might be bad, causing it to read the wrong temp. The fact that it is jumping around like that points to this kind of problem.

Hi: Does the freezer have a battery backup for the electronics? A 9v. battery in the grill down below. You won't have to remove the grill but pull a small rectangular panel to expose the battery. High end Kenmore freezers have a battery to back up the alarm. The six you see is actually supposed to be a "b" for battery most likely. L.E.D.'s are tough to tell the difference. Buy an new battery and all will be well. I hope this helps, Jeff

I think your freezer's coils have been damaged. Consult a enjinner.
