Went to start a walk-in cooler after years of down time. The compressor will run for about 10 seconds then shut off for about 30 seconds then run for another 10 & shut off for another 30. Any ideas?
Hi,
It has lost some freon and is not charged correctly...the unit is pumping down and shutting off on low pressure and then after being off a bit the pressure comes up and it restarts...
Need to check the charge and top it off and you will be good to go..

Testimonial: "Thanx for the good advice."
In most of the cases when refrigerant system has holes in it would leak out refrigerant, once it gets low enough it will start cycle off at low pressure switch. Check this video from 5th minute in, we found multiple leaks on that walk in cooler, on of them was at the valve up on the roof (not a big deal), another one was at the middle of evaporator coil (had to replace coil). I hope this helps.
