Hey I hope someone can help me here. I have a walk-in cooler that is 10x14x7. I have the head pressure going to 170 and the suction to 43. My temp on the inside cooler is at 38 to 40 degrees. this is an R-22 system. According to the pt chart my suction should be around 69. I have cleaned the evap. The condensing fan stays running and the fans inside shut off. the condenser is clean. If I put a temp. probe where the evap is it drops to 28 to 32. Can anyone tell me why the system is shor cycling. I appreciate your help and thank you for it. Techman49
