Lennox 12L21 Pressure Switch
As a seasoned technician, you know that safeguarding the compressor from low-side pressure drops is critical for system longevity. The Lennox 12L21 Pressure Switch is an OEM low pressure safety switch meticulously calibrated to monitor refrigerant levels and prevent vacuum conditions or evaporator freeze-ups. Designed for integration into Lennox HVAC systems, including high-efficiency condensing units and heat pumps, this Normally Open (NO) switch features 8-inch leads and a robust 120/240VAC 5.8 Amp contact rating. Field-tested for reliability, the 12L21 actuates at 40 PSI and provides an automatic reset at 25 PSI, ensuring your refrigerant pressure monitoring remains precise. Whether you are performing a routine sensor replacement or troubleshooting a compressor lockout, this genuine Lennox replacement part (Model 100087-15) offers the exact electrical specifications and physical fit needed to restore factory-standard protection without the guesswork of universal alternatives.
