cycling time

[justtrying]

I have a large vegtable cooler, it runs off MP_39. Everything runs fine until it gets down to temperature then it starts to short cycle. It has a snap acting temp control that closes when it reaches temp, open when the box needs to cool. It has pressure contol on the compressor. Any and all help will be greatly appreciated. Suction press 24 discharge press 200 :confused:

The refrigeration forum might be better for this question, but maybe you just need to adjust the differential.
