The genuine OEM Lennox 92W92 is a 40+7.5 MFD, 370V round dual run capacitor engineered to deliver the starting torque and running charge for both the compressor and condenser fan motor in your Lennox outdoor unit. As a dual-rated component, it supplies two separate microfarad values from a single housing, keeping your system's motors turning at rated efficiency and protecting them from voltage stress.

Common failure symptoms: A weak or failed capacitor is one of the most frequent causes of air conditioner breakdowns. Watch for a compressor or fan motor that hums but won't start, a fan that spins slowly or intermittently, warm air from the vents, tripped breakers, or a visibly bulging, leaking, or swollen capacitor top. Capacitors degrade over time from heat cycling, so replacement often restores full cooling immediately.

Why OEM matters: The Lennox 92W92 is built to the exact capacitance, voltage, and tolerance specifications your equipment was designed around. Generic substitutes with mismatched MFD ratings can shorten motor life, reduce efficiency, and void warranty coverage. Choosing the factory-specified part ensures precise fit, reliable performance, and the longest possible service life for your Lennox system.

Frequently Asked Questions

Does this Capacitor fit my Lennox OEM Lennox Dual Run Capacitor 40+7.5 MFD 370V Round — 92W92?
Yes. This is the factory-specified OEM capacitor for the Lennox OEM Lennox Dual Run Capacitor 40+7.5 MFD 370V Round — 92W92. It is a direct drop-in replacement that fits without modification. Always verify the model number on your equipment nameplate before ordering.
How do I replace the capacitor on my Lennox OEM Lennox Dual Run Capacitor 40+7.5 MFD 370V Round — 92W92?
Difficulty: Easy (20–30 min)
Step 1: Turn off power at breaker. Step 2: Open condensing unit panel. Step 3: Photograph the old capacitor wiring (Common/Herm/Fan). Step 4: Discharge old capacitor with insulated screwdriver. Step 5: Disconnect and remove old capacitor. Step 6: Mount new capacitor, reconnect wires to matching terminals. Step 7: Close panel, restore power, test. Tools: screwdriver, needle-nose pliers.
My AC hums but won’t start. What part do I need?
An AC that hums but won’t start is the classic symptom of a failed capacitor. The capacitor provides the electrical boost to start the compressor. When it fails, you hear humming but the motor can’t overcome inertia. Other symptoms: fan spinning slowly, AC cycling on/off rapidly, or a visibly swollen capacitor. Fix: replace capacitor ($15–$80 DIY, 30 min).
Is this capacitor compatible with Bryant or Payne too?
Many Lennox parts are cross-compatible with Bryant and Payne since all three brands are manufactured by Carrier Global Corporation. The same physical part is often used across brand labels with different model numbers. To verify: check your Bryant or Payne equipment service manual for cross-compatible part numbers, or email info@nationalhvacparts.com with your model number.
Should I use OEM or aftermarket for my Lennox capacitor?
OEM strongly recommended. OEM capacitors have ±6% MFD tolerance vs aftermarket ±10%. The looser tolerance causes motor winding stress, higher temps, and shorter compressor life. Price difference is only $10–$20 — OEM is the clear value choice.
How fast does National HVAC Parts ship?
