Your shift briefing
A walk-in cooler is not holding temperature and the store manager is counting spoiled stock. The system is running, which means the problem is in the numbers: pressures, temperatures and the superheat that tells you whether the evaporator is doing its job. Work the cycle like a refrigeration tech - understand what each reading means, then tune the system so the compressor gets cool gas, not liquid.
