Electricity for refrigeration usually falls into one of two categories- single phase and three phase.
Each has its own set of problems.
What have I seen over the years?
1. Start Components: Many single phase repairs involve the potential relay, start capacitor and run capacitor.
2. Single phase condition: This is a very common problem when using three phase equipment.
3. Control system: The control system can make the equipment do crazy things.
4. Voltage problems: Sometimes it's not the unit creating havoc.
5. Amperage problems: The compressor RLA and RLA and LRA are very important.
6. Three phase monitors: Three phase electricity for refrigeration units must be properly monitored. But don't forget the simple things. Look around closely, the problem may be looking back!
