E9 code Model 253.28432809 Code E9 shows on display and freezer runs constantly and gets extremely cold. Cannot raise temp or lower with code on display. Only thing I can do is Lock it or turn it OFF. Need to know what E9 means and how to remove so I can set the Temp?

SOURCE: freezer temp display beeping and going through different temps rapidly!

Seems that you may have a faulty temp control switch or it is stuck in position. Check this also make sure that the air vents are clear.

Thanks J
