Room Air Conditioner Switch

This run capacitor helps the appliance motor keep steady torque during operation for reliable performance and smoother starts. It replaces a worn or failed capacitor to restore normal motor function and reduce abnormal noise or cycling. What it does:

• Provides continuous phase shift and stored energy to help the motor run efficiently
• Common symptom: motor hums but won't start or has weak starting torque
• Common symptom: motor runs intermittently, stalls, or cycles on and off
• Common symptom: unusually noisy motor operation or reduced performance

• Disconnect power to the appliance before accessing or replacing the capacitor
• Capacitors can hold charge—discharge safely
• Match terminal types and mounting style to the original part for proper fit

A compressor protector that helps prevent compressor damage by interrupting power when the motor overheats or draws excessive current. Replaces a failed protector to restore proper compressor protection and help avoid costly compressor replacement. What it does:

• Senses excessive heat or current at the compressor and opens the circuit to stop the compressor from running.
• Helps prevent compressor burnout and wiring damage caused by overheating or locked-rotor conditions.
• Common symptom linkage: refrigerator runs but cooling is poor or compressor will not start and only hums intermittently.
• Works with the compressor start system to improve reliability when the protector is functioning correctly.

• Disconnect power to the appliance before starting any repair.
• Mount and connect the protector to the compressor terminals exactly as the original part was installed.
• Handle terminals carefully to avoid bending or damaging compressor leads.
• If the compressor or start components show other signs of failure, inspect the start relay, overload, and wiring; replace any damaged parts.

This start/run capacitor helps provide the extra boost motors need to start and run reliably in the cooling system, restoring proper motor operation and helping the appliance maintain normal cooling performance. What it does

• Provides the temporary electrical boost motors need to start and run smoothly.
• Commonly replaced when a compressor or condenser fan hums without starting.
• Can correct intermittent motor loss-of-power or hard-start symptoms.
• Works as part of the motor starting circuit to improve overall reliability.

• One capacitor as shown.

• Disconnect power to the appliance before accessing electrical components.
• Discharge the capacitor before handling to avoid electric shock.
• Replace only with the exact capacitor type and ratings specified by the manufacturer.
