It's not getting hot and the compressor was replaced late last year. I need to know which way to turn the dials on the top of the Ranco unit to get the desired temperature range.

Sorry wrote to you by mistake.

Hello, so far it should like you have a model number 1402 ranco low pressure control, those have two knobs on the top. and some instructions on the on the face of the control under the pointers that says, 'cut in is cut out minus the differential' or similar.

Let me know the exact working, and where each pointer is set at, we can go from there.

Thanks Phil....I had the refrigerator rebuilt last year. What started all this was it started running really cold a month or so ago. I moved it out from the wall and found a large build up of dust on the fan in the back. I cleaned it off and the fridge ran fine after that. The problem was that I "fiddled" with the dials on top of the Ranco before cleaning off the dust in the back. Now I can't seem to get them set right. It runs for short spurts and keeps things cold but I know the cycle should be longer with more of a span in temperatures between low and high. My refrigerator guy retired and I can't contact him any longer. I will get online when I get home this evening and be in touch with you. I am on Mountain Standard Time.

Hello again, sometimes one or both knobs on top are removed, tell me what each knob, or the single remaining knob, says on top ......and if there is an arrow on the knob that says "increase. decrease, colder or warmer'... get me some photo's of the top showing the knobs as viewed from the top, and the front of the control with beige plastic cover removed, (the older covers are black painted metal)... it will be one or the other.

We can go from there.
