Lennox 1100600-01 Run Capacitor – 5 MFD, 370V, Oval – Cat # 22W78

The Lennox 1100600-01 Run Capacitor, catalog number 22W78, is a 5 MFD, 370 VAC oval run capacitor designed for compatible Lennox HVAC motor applications. It provides the required capacitance to help compatible PSC motors maintain proper operation and performance.

With its 5 MFD rating, 370V capacity, and oval configuration, the Lennox 22W78 is ideal for replacing an existing capacitor when the original equipment specifications call for the same capacitance and voltage requirements.

🛠️ HVAC Depot Pro Tip: Match the 5 MFD Rating

When replacing the Lennox 1100600-01 / 22W78, make sure the motor requires a 5 MFD run capacitor.

The MFD rating should match the motor requirement. Installing an incorrect capacitance can affect motor performance, increase operating temperature, and potentially shorten motor life.

A 5 MFD / 440V capacitor can generally replace a 5 MFD / 370V capacitor, provided the replacement physically fits and meets the equipment requirements. The higher voltage rating is acceptable; the 5 MFD capacitance should remain the same.


Cross-Reference & Part Identification

Lennox

Catalog #: 22W78

Model/Part #: 1100600-01

Capacitance: 5 MFD

Voltage: 370 VAC

Shape: Oval

These numbers are useful for customers searching by either the Lennox catalog number or the number printed on the original capacitor.


Equipment & Model Compatibility

The Lennox 22W78 / 1100600-01 is intended for select Lennox HVAC applications requiring a 5 MFD, 370V oval run capacitor, including compatible:

• Lennox Air Conditioners

• Lennox Heat Pumps

• Lennox Condensing Units

• Condenser Fan Motors

• Blower Motors

• PSC Motors

• Residential HVAC Equipment

• Light-Commercial HVAC Equipment

Always verify compatibility using the equipment model/serial number and motor capacitor requirement before ordering.
