Heat Controller R68DD0014 Pressure Switch
The Heat Controller R68DD0014 Pressure Switch is a critical safety and operational component designed for negative pressure monitoring in residential and light commercial HVAC systems. Calibrated to a precise -.2" WC (Water Column) set point, this diaphragm-actuated switch ensures the draft inducer is venting combustion gases effectively before allowing the ignition sequence to proceed. Engineered for compatibility with Comfort-Aire, Century, and Mortex gas furnaces?specifically models such as the G18D060, G18D070, G18D077, and G18D090?it provides a normally open (N.O.) contact configuration that closes only when the specific vacuum threshold is reached. This furnace air pressure switch features a robust polycarbonate housing and standard 1/4" spade terminals for direct integration into existing control circuits, maintaining system integrity and preventing operation during venting obstructions or inducer failure.
Key Benefits:- Precise Pressure Tripping: Fixed -.2" WC set point prevents nuisance tripping while ensuring high-accuracy vacuum sensing.
- Broad OEM Compatibility: Direct replacement for Mortex and Heat Controller furnace units, facilitating rapid field service.
- Enhanced Safety Logic: Reliable SPST N.O. operation prevents burner ignition in the event of restricted flue venting or mechanical inducer failure.
- Professional Grade Construction: Features a durable sensing diaphragm and glass-filled housing for longevity in high-temperature environments.
- How do I know if the R68DD0014 is failing? If the inducer motor runs but the ignition sequence does not start, or if your control board flashes a code for "Switch Stuck Open," the pressure switch or the venting system should be tested with a manometer.
- Can I use a switch with a different WC rating? No. Pressure settings are specific to the heat exchanger and inducer design; installing a switch with a different rating than the -.2" WC specification can result in unsafe operating conditions.
- Does this switch support positive pressure sensing? While some switches are universal, the R68DD0014 is specifically designed for negative pressure (vacuum) sensing within the burner or inducer housing.
