There are a couple cites I that service, mainly the hvac, where I notice the compressors for the walk-ins keep short cycling for a bit while the system already is pumped down, and then it stops. Next month we will be doing our refrigeration pms so I’ll have more time to dive into these systems. I initially thought it could potentially be the dual pressure switch going out of calibration, but after looking online it could potentially be an issue with the solenoid valve bypassing or the compressor.

Those are just my assumptions as someone with limited walk-in experience. What I’m wondering is what should I actually look for? Would it be a good idea to wire a compressor delay in series to the contactor to prevent short cycling while the system is pumped down?
