Lennox 26W38 Run Capacitor
The Lennox 26W38 Run Capacitor is a mission-critical component designed for high-performance HVACR motor and compressor applications. This 40 Microfarad 370Vac unit is engineered to provide precise phase-shifting for single-phase induction motors, ensuring optimal torque and operational efficiency. Built with a round can configuration, the 26W38 utilizes non-PCB dielectric fluid and internal pressure-sensitive interrupters to prevent housing rupture during an end-of-life electrical event. Rated for 50/60Hz, this 40 MFD capacitor maintains a standard +/- 5% capacitance tolerance and is officially recognized as identical to part 26W3801. For technicians replacing older service stock, this unit serves as a direct drop-in for discontinued Lennox numbers such as 53H01, 81A47, and 96C48. The 370V rating provides robust protection against back EMF, though it should only be used in systems where the operating voltage does not exceed the nameplate specification. Ensure secure lead connections at the terminals to minimize resistive heating and premature dielectric breakdown.
Key Benefits- OEM Compatibility: Replaces Lennox 26W3801, 53H01, 96C48, 81A47, and 39H58 without modification.
- Thermal Stability: Designed for continuous duty in high-ambient condensing units.
- Leak Protection: Hermetically sealed round aluminum casing prevents oil migration and protects internal foil layers.
- High AFC Rating: Features a 10,000 Amp Interrupting Capacity (AFC) for enhanced safety during circuit faults.
Can I use this 370V capacitor to replace a 440V unit?
No. While capacitance (40 MFD) must match, the voltage rating of the replacement must be equal to or greater than the original part. Using a 370V capacitor in a 440V application will lead to immediate dielectric failure.
Does this capacitor replace the oval-style 40 MFD units?
Electrically, yes, provided the specs match; however, the round form factor may require a different mounting strap or bracket compared to traditional oval capacitors.
What are the signs that my 26W38 capacitor has failed?
Typical failure indicators include a "mushroomed" or bulging top, oily discharge around the terminals, or a compressor that hums but fails to start (LRA condition).
