Lennox 28M96 Ignitor

The Lennox 28M96 Ignitor is a critical 120-volt silicon carbide hot surface ignitor designed for high-performance residential and commercial gas furnaces. Engineered as a direct OEM furnace replacement part, the 28M96 ensures reliable ignition sequences by reaching necessary combustion temperatures rapidly. Within the trade, the Lennox 28M96 is recognized as identical to 28M9601, 601 1104, and Norton 204-342-01, offering broad compatibility across Lennox, Armstrong, and Ducane platforms. As a furnace ignition system component, it is commonly utilized in the CMPE100U4 model series. Field technicians often prioritize this unit for its durability and precise fit, which eliminates the need for harness modifications. When troubleshooting a furnace not heating, verifying the ignitor resistance—typically between 39 and 70 ohms—is the standard procedure for identifying a failed element before a complete lockout occurs.

Key Benefits

• Universal Compatibility: Seamlessly replaces Lennox 28M9601 and Norton 204-342-01 without modifying the existing wiring harness.
• OEM Precision: Specifically calibrated for models like the Lennox CMPE100U4 to ensure the gas valve opens only after the element reaches peak temperature.
• Robust Construction: Features a protective slim metal casing to shield the fragile silicon carbide element during installation and operation.
• Efficient Ignition: Designed for an optimized warm-up period, reducing wear on the control board and ensuring 120V system stability.

Common Questions

How do I check if my Lennox 28M96 Ignitor is bad?
Use a multimeter to perform a resistance test. Set your meter to ohms and check the pins at the Molex connector; a reading outside the 39-70 ohm range typically indicates a hairline fracture or "dead patch" in the element.

Is the 28M96 the same as the 28M9601?
Yes, these parts are technically identical. The 28M96 is the base part number used interchangeably with 28M9601 in most Lennox and Allied Air technical manuals.

Can I touch the black element during installation?
No. Avoid touching the silicon carbide surface with bare hands. Skin oils can create "hot spots" that cause the ignitor to fail prematurely during the first few heating cycles.
