OEM Carrier Dual Run Capacitor & Start Capacitor Kit for Model PH13NR036000ACAA

This factory-matched capacitor kit contains both the P291-5073RS Dual Run Capacitor and the P281-8806 Start Capacitor — the two OEM-specified capacitors for the Carrier PH13NR036000ACAA heat pump condenser. The dual run capacitor continuously powers both the compressor and condenser fan motor during operation, while the start capacitor delivers the high-torque kick needed to start the compressor under load. When either fails, symptoms include a humming unit that won't start, a compressor that trips on thermal overload, short-cycling, or a system that trips the breaker immediately after startup.

• Dual Run Capacitor (P291-5073RS) Specs: 50+7.5 MFD (microfarad) | 370V rated | Round case | Factory-matched ±3% tolerance — powers both the compressor and condenser fan motor simultaneously
• Start Capacitor (P281-8806) Specs: 88–108 MFD | 330V rated | Round case with integrated bleed resistor — provides compressor start-boost and safely self-discharges between cycles
• OEM vs Generic: OEM capacitors meet Carrier's exact factory tolerances. Aftermarket units commonly run ±10% MFD deviation, placing excess stress on the compressor windings and shortening equipment life — especially critical in a heat pump that runs year-round.
• Install Difficulty: 2/5 — Always discharge capacitors before handling (both can retain a lethal charge). Tools needed: 1/4" nut driver, insulated needle-nose pliers, multimeter with capacitance mode. Photograph all wiring before disconnecting. The start capacitor includes a bleed resistor — do not bypass it.
• Warranty: 1-year OEM factory warranty on both components. Ships same business day from our warehouse in original Carrier/Totaline packaging.

Compatibility: This kit is factory-specified for the Carrier PH13NR036000ACAA 3-ton heat pump condenser. Always verify the MFD and voltage ratings on your unit's data plate before installation.
