Carrier 312926-240 Pressure Switch
The Carrier 312926-240 is a high-performance OEM high pressure switch specifically engineered for Carrier, Bryant, and Payne HVAC units. Designed for critical system protection, this condensing unit pressure switch monitors the high-side refrigerant circuit to prevent compressor damage and mechanical failure due to excessive head pressure. With a precise cut-in pressure of 670 PSI and a cut-out pressure of 470 PSI, it ensures that your system operates within safe manufacturer-specified limits. This HVAC high pressure manual reset switch is a direct replacement for Carrier part number 312926-240, maintaining the original factory safety logic and performance standards required in demanding cooling applications. As a veteran tech knows, a failing switch often leads to intermittent AC short cycling or total system lockout; replacing it with a genuine Carrier refrigerant pressure switch is the best way to ensure long-term reliability and precise pressure management for your clients' equipment.
Key Benefits:- Precise Pressure Calibrated: Features a factory-set 670 PSI trip point and a 470 PSI reset point for accurate high-pressure protection.
- OEM Compatibility: Guaranteed fit for numerous Carrier models, including 38EYA and 38EYG series air conditioners and heat pumps.
- Durable Construction: Built to withstand harsh outdoor environments and high-vibration conditions within the condensing unit.
- System Safety: Protects the HVAC compressor from thermal overload and structural damage caused by restricted airflow or overcharging.
What are the symptoms of a bad Carrier 312926-240 pressure switch?
Technicians typically see the system trip on a high-pressure lockout. If the switch fails "open," the compressor will not engage even if the contactor is pulled in. If it fails "closed," it loses its ability to protect the system during a fan failure or blocked condenser coil.
How do I test the 312926-240 switch in the field?
Using a multimeter set to continuity, check the terminals while the system is off. On a high-pressure switch like this, you should see 0 ohms (closed) under normal standing pressures. If you measure an open circuit at rest, the switch is likely tripped or defective.
Does this switch require a manual reset?
Yes, this is a manual reset high-pressure safety. Once the system pressures drop back below the 470 PSI cut-out threshold, the technician must manually depress the reset button to restore operation.
Item is Non Cancelable / Non Returnable
