What's the Kenmore 2804 auto defrost cycle? Can I make it manual defrost?

I am considering purchasing the Kenmore Freezer 2804 (Model 28042, Sears item# 04628042000), but am concerned about the heating cycle when auto defrosting. I am freezing items for a research laboratory. What heating cycle does it go through? What temperature does what part of the freezer go to, and for how long? If I have an item on the shelf, does the item touch something that gets heated up?

Is it possible to disconnect the auto defrost aspect of it, so that I have to manually defrost it? Since it was originally intended for auto defrost, would it get frosty much sooner than a unit originally intended for manual defrost?

This freezer has an electronic control board and the defrost system cannot be disconnected. It's built into the board. It will go into a defrost every 12 hours of compressor run time and last for 30 minutes. There is a heating element next to the evaporator that heats up. There is no set temperature it will heat up to, it can vary due to different loads and door openings. I hope this will help you.

Sorry, I had the wrong freezer. The correct one is 253.28052800. If we disconnected the auto-defrost, in what way would it not work properly?
Would it require manual defrosting much more often than a freezer that is designed for manual defrost?
If we leave the automatic defrost as-is, what is it that heats-up? What does the inside temperature go up to? For how long does it heat-up?
Thanks!

Thank you for your question. The model number listed is not complete and it shows several freezers. However, all the freezers listed are manual defrost freezers. There is no defrost system in these freezers. However, if it did have a defrost system the items on the shelves would not contact anything hot. An auto defrost system could be disconnected in some models but if it were disconnected, the freezer would not work properly. I hope this will help you. If you would like more assistance, the complete model and serial number will be needed and any additional details will be helpful. Thank you for using Manage My Life.

Thanks for the suggestion. It's a challenge to find the 'full model number' without having purchased it, and with limited Sears personnel to contact, but I'm betting there is sufficient information for the Expert to provide a reasonable reply.

I know how important it is to have a refrigerator with many different cycles so that you can choose just the right cycle for your food. While you are waiting for your expert answer, I suggest you add to the thread of this question and include the full model number of the refrigerator so that the expert can provide you with a more detailed answer. I did manage to find a link that will provide you with some good information. I hope my link is useful.
