• Protects the compressor by opening the circuit if current draw or temperature is excessive
• Helps with: compressor won't start, repeated clicking from the rear, warm/not cooling temperatures, or a rattling/burnt start device

• One start device assembly

• Disconnect power before servicing; work in a well-ventilated area

• Safely discharge any start/run capacitor per manufacturer procedure
• Push the new device fully onto the compressor terminals, secure any cover, then restore power and verify operation
