Reznor 195643 Capacitor

The Reznor 195643 Capacitor is a task-specific 7.5 MFD 440V electrical component engineered for high-demand HVAC motor starting and continuous run applications. As a genuine HVAC OEM capacitor, this unit provides the necessary phase shift to optimize inducer motor and blower fan performance in Reznor gas-fired unit heaters. Its rectangular run capacitor geometry is designed for direct integration into compact control compartments, ensuring a secure fit in the UDAS, UDAP, and UDZ series air handlers.

Built with a durable metallized polypropylene dielectric and housed in a robust molded case, this 7.5 microfarad 440VAC component operates reliably across a wide temperature range of -40 to 70 °C. The quick connect terminal configuration streamlines swap-outs during routine maintenance or emergency service calls. By maintaining stable electrical flow and consistent capacitance, it prevents motor overheating and reduces excessive amp draw on 115V or 208/230V circuits. For contractors servicing commercial heating units, this 195643 capacitor replacement is essential for restoring factory-sec blower speed and system efficiency.

• Broad Compatibility: Engineered specifically for Reznor unit heater models including the UDAP and UDAS 100-400 series.
• Optimized Motor Life: Stabilizes voltage to the venter motor, preventing premature winding failure caused by fluctuating electrical loads.
• Industrial Standard Rating: Rated for 440 volts, providing superior overhead and longevity compared to standard 370V alternatives in 60 Hz environments.
• Streamlined Installation: The compact, rectangular design allows for precise placement in restricted unit heater housings.

Is the 195643 compatible with 115V and 230V Reznor units?
Yes, this capacitor is designed to work in both 115V and 208/230V configurations, provided the motor requirements match the 7.5 MFD specification.

Can I use a round capacitor instead of this rectangular model?
While electrical ratings may match, the physical footprint of the 195643 is necessary for proper mounting and clearance within the manufacturer's specified bracket or enclosure.

What are the symptoms of a failing blower motor capacitor?
Technicians should look for humming sounds without motor rotation, intermittent fan startups, or visible swelling of the capacitor casing.
