Curious to hear from other techs and installers working in commercial refrigeration.
When working on supermarket rack systems, what’s the most common issue you run into in the field?
I’ve seen a lot of problems related to condenser coil buildup, fan motor failures, and sometimes oil management issues after long operation. Preventive maintenance obviously helps, but it seems like certain components fail more frequently depending on the system design.
For those working in grocery stores or large commercial setups, what failures do you see the most and what usually causes them?
