Training
If you can't read the circuit, you can't find the fault
Electrical & Controls
A huge chunk of refrigeration faults are electrical or control-related. We teach you to read control circuits, fault-find electrical components, and understand the controls that run modern refrigeration systems.
Reading control circuits
- Schematics: L1/N, switches, relays, contactors.
- Following a circuit to find the open, not just the dead part.
Components and their failures
- Contactors, overloads, capacitors, relays.
- Sensors, controllers and boards.
- What fails and how it shows up.
Control strategies
- LPs, HPs, oil pressure safety.
- Pump-down and defrost controls.
- Temperature control and staging.
Fault-finding electrical
- Safe, methodical meter work.
- Testing, not guessing.
What you'll get
- Read control circuits with confidence
- Fault-find electrical issues methodically
- Understand the controls running the system
