Your Bryant air conditioner depends on a healthy start capacitor to deliver that critical initial surge to the compressor and fan motor.

Repair Clinic stocks genuine OEM start capacitors engineered to Bryant's exact specifications—the same quality your system needs to perform reliably through hot seasons.

A humming sound with no compressor or fan motor rotation almost always signals a failed start capacitor. This part provides the electrical boost needed to overcome inertia and get the motor spinning. Without it, your compressor locks up. A replacement OEM capacitor restores that starting power quickly.
Your Bryant model number is located on the nameplate, typically found on the side or back of the outdoor condenser unit. Look for a label that starts with "58" or "59." Write down the full model number and check it against Repair Clinic's database to ensure you order the exact capacitor your system requires—mismatched ratings can damage motors.
Start capacitors deliver a high-voltage burst for just a fraction of a second to spin motors from rest. Run capacitors stay energized throughout operation to maintain efficient motor performance. Bryant units often use both types. If your AC won't start but runs fine once spinning, the start capacitor is likely your culprit.
Always power down your Bryant unit at the breaker and discharge the capacitor before touching it—stored electrical charge can cause serious injury. If you're not confident with electrical work, hire a licensed technician. Repair Clinic supplies the parts; professional installation ensures safety and model-specific fit and performance.
