I just bought a new Norlake freezer that I continuously open and close because its busy. What's the best temperature to set and the best temperature differential to set? How many times a day should it defrost?

temperature may be to high and is freezing the door close, just set it up to the lower temperature. ref. side 40f freezer side 0f

The best temperature for storing food is 0 degrees F. I would go to Wal-Mart, K-mart or a dollar store and find a refrigerator/freezer thermometer and set the freezer temperature with that. Best of Luck

Normally, freezers are at 0 degrees. If you have ice cream, shoot for -10 degrees.

hope this is what you are looking for.

Normally freezers are kept at zero. Most health departments will not allow the temp to be higher than plus 10. If you want to store ice cream, you need to be at minus 10 degrees to minus 15 degrees.

let me know if I can be of any further help.

I've worked on freezers for over 20 years and have never heard of a compressor going bad because the door was left open. think about a second opinion.
Also, has the cooling coil inside the box developed and frost or ice build up? If so, it needs to be completely defrosted. If you defrost it manually, use a hose hooked up to hot water. Kill all power and hose all build up off. Remove the sheet metal housing ends and be sure there is no ice inside there too. I would go in this direction first.
IN order to kill a compressor under this condition, something really strange must have happened as anything is possible in a refrigeration system. Good luck and hope this helps.

As long as the temp. stays around 5+ or 5- of 0 degrees everything should be okay.

Hi, If you had ice, there is a drain plugged in the freezer. If you had a frost build up, there is a problem with the automatic defrost.

I can help in either case. Please let me know if you need more assistance.

The factory presets your temperatures to the MID / MID setting of 0ºF for the freezer.

If your products are already in the frozen state the answer is yes, you can make an immediate transfer. Normally a couple of hours run to allow the temperatures to stabilize is sufficient. The cool down run time also insures the the unit is functioning properly. If you plug it in and transfer the products right away make frequent checks to insure proper operation.

They are usually mounted on the front panel of the evaporator or mounted on the wall behind the evaporator.There is a possibility that the temp. control is at the condenser,and the sensing bulb was slipped thru the wall.Look for the bulb at the back of the evaporator and follow the cap tube.
