Description
Carrier P281-1356 Round Start Capacitor Overview
The Carrier P281-1356 is a genuine OEM round start capacitor engineered to deliver reliable motor starting performance in Carrier HVAC systems. With a capacitance range of 135–155 microfarads (MFD) and a rated voltage of 320VAC, this capacitor provides the high-torque starting boost that compressor and fan motors demand during every startup cycle.
Key Specifications
- Capacitance Range: 135–155 Microfarads (MFD)
- Rated Voltage: 320VAC
- Form Factor: Round
- Capacitor Type: Start Capacitor
- OEM Part Number: P281-1356
- Brand: Carrier
Features & Benefits
- Genuine Carrier OEM replacement for assured compatibility and performance
- Wide capacitance tolerance (135–155 MFD) supports consistent motor starting across varying load conditions
- 320VAC rating provides a reliable safety margin for residential and light commercial HVAC applications
- Round form factor fits standard capacitor mounting brackets and housings
- Designed to reduce motor wear by delivering proper starting torque and quickly dropping out of the circuit once the motor reaches operating speed
- Helps restore system efficiency and extend equipment life when replacing a failed or degraded start capacitor
Application
The P281-1356 start capacitor is intended as a direct OEM replacement for compatible Carrier heating, cooling, and heat pump systems. Start capacitors are a critical electrical component — they energize the start winding of single-phase motors to generate the torque needed for startup, then disengage once running speed is achieved. Replacing a failed start capacitor promptly prevents hard-start conditions, motor burnout, and compressor damage.
Installation Notes
- Always discharge capacitors before handling — stored charge can cause serious injury
- Verify capacitance (MFD) and voltage ratings match the original capacitor before installation
- Consult Carrier equipment documentation or a qualified HVAC technician for proper installation procedures
