    lets all slow down.

    I think were all talking different things here. And I mucked it up even more.

    If it is a service meat case, or a multideck meat merchandiser, then a 28 degree discharge air temp is the acceptable means to acheive meat optimum temp. Actualy, anything above 30 degrees and your shelf life will go to $hit.

    If it is service deli, and I don't think it is, after rereading the first post and after I assumed it was and went way long in the wrong direction on my first post, then we got different things to look at. As a matter of fact, if it's service deli, alot of what I said in my first post I will keep.

    The poster said MEAT. Meat has to be kept at 28 to 30. Above that and your customer will be very upset with you.

    If you can't tell the difference between a bad defrost clock and low on charge, I would tell him to call a pro.
