Lennox 100335-56 Dual Run Capacitor – 30/10 MFD, 440 VAC, Round – Cat # 99W98

The Lennox 100335-56 Dual Run Capacitor, catalog number 99W98, is a 30/10 MFD, 440 VAC round dual run capacitor designed for compatible Lennox air-conditioning and heat pump applications.

Its dual-capacitance design allows one capacitor to support both the compressor and condenser fan motor. The 30 MFD section typically serves the compressor (HERM), while the 10 MFD section typically serves the condenser fan motor (FAN).

🛠️ HVAC Depot Pro Tip: Match Both MFD Ratings

When replacing the Lennox 100335-56 / 99W98, both capacitance ratings should match the equipment requirements:

30 MFD → Compressor / HERM

10 MFD → Condenser Fan Motor / FAN

Do not substitute a 30/10 MFD capacitor with a 30/5, 35/10, 40/10, or another combination simply because the capacitor fits physically.

Before installation, verify:

30/10 MFD rating

440 VAC rating

• Round physical configuration

• Terminal identification

• Equipment model and specifications

• Compressor capacitor requirement

• Condenser fan motor capacitor requirement

Always identify the C (Common), FAN, and HERM (compressor) terminals correctly when transferring wires.


Cross-Reference & Part Identification

Lennox

Cat #: 99W98

Model/Part #: 100335-56

Capacitance: 30/10 MFD

Voltage: 440 VAC

Shape: Round

Type: Dual Run Capacitor

Customers may search for this capacitor using either 99W98 or 100335-56, so including both numbers in the product title and description improves product search visibility.


Equipment & Model Compatibility

The Lennox 99W98 / 100335-56 is intended for select Lennox equipment requiring a 30/10 MFD, 440 VAC round dual run capacitor, including compatible:
