What should the inside temperature be on an upright freezer? Is setting 4 or 5 correct?

kenmore elite, alarm kept going on and b flashed on and off. I finaly figured out on bottom of freezer there is a battery door open it and change 9v. thats it,

It is usually reccomended to let it stand in it's normal position for 24 hours prior to running to allow any oil to run back to the compressor. Unit should work.

Yes you need to replace it,if dont will have bigger problems.

call sears 800 parts

It sounds like the unit is low on freon or the compressor is going bad. You have several other components that could be affecting this as well. Make sure the coils are free from dust and clean underneath. This is a bit premature for you to have problems now, especially since it is a Sears product.

Go to sears parts direct website. It's part #3206261 and is in stock, $93.07. Good Luck! countrycurt0
