🔍 Key Concepts

• Basic electrical troubleshooting sequence for motors • Difference between electrical faults and system (pressure/valve) faults in refrigeration • Safety and simplicity: what can be checked quickly without opening the system

💭 Think About

• Before worrying about pressure controls or valves, what must be true for any motor to run at all? • Which option can prevent power from reaching the motor instantly, without involving refrigerant pressures? • Which checks would normally be done without tools or system disturbance as a first step?

✅ Before You Answer

• Identify which choice is a simple electrical supply/interruption issue • Identify which choices involve refrigerant pressure or flow control rather than power to the motor • Ask: In a safe, logical troubleshooting order, what is the very first, quickest check you would make before adjusting any controls or opening the system?
