Lennox 13R80 Pressure Switch
The Lennox 13R80 is a high-reliability low pressure switch designed specifically as a safety cut-out for residental and commercial air conditioning and heat pump systems. For technicians diagnosing a system lockout or a failure to initiate the refrigerant compression cycle, this OEM component provides the precise mechanical actuation required to protect the compressor from low-suction conditions and potential oil slugging. Pre-set at the factory, the 13R80 features a 40 PSI actuation point and a 25 PSI reset, making it a drop-in replacement for aged Lennox 614285-05 and 11Y34 controls. Effectively identifying a faulty pressure switch requires verifying that the SPST-N.O. contacts respond correctly to manifold gauge readings; this switch is rated for 120/240 VAC with a 6-amp full-load capacity to handle standard control circuit draws. Built for durability in extreme environments, it operates within a temperature range of -30°C to 80°C and includes 45-inch lead wires for versatile routing and secure electrical terminal connectivity.
Key Benefit List:- Compressor Protection: Prevents terminal damage by monitoring for low charge or restricted flow, interrupting the circuit before the compressor overheats.
- Precise OEM Calibration: Pre-set at 40 PSI trip and 25 PSI reset to maintain the exact safety margins specified by Lennox engineering.
- High-Compatibility Design: Directly replaces legacy part numbers including 11Y34, 614285-05, and Sensata PS80 series components.
- Heavy-Duty Construction: Environmentally sealed to withstand high ambient temperatures and vibration common in condensing units.
- Streamlined Installation: Features 45-inch factory-stripped leads to simplify integration into existing control logic boards or contactor circuits.
- How do I troubleshoot a 13R80 if the compressor won't kick on? Check for continuity across the terminals while the system is under standing pressure. If the pressure is above 40 PSI and the switch remains open, the internal diaphragm or contacts have likely failed.
- Can this switch be used in R-410A systems? Yes, this switch is designed to monitor low-side suction pressure across various refrigerant types, provided the system operating parameters align with the 40/25 PSI setpoints.
- What causes these switches to trip frequently? Frequent tripping usually indicates a genuine system issue, such as a refrigerant leak, a failed thermal expansion valve (TXV), or a restricted liquid line filter drier rather than a switch defect.
