OEM vs. Generic

OEM Goodman pressure switches are calibrated to the exact cut-out and cut-in set points your system's control board expects. Generic switches may trip at incorrect thresholds, causing nuisance shutdowns or leaving the compressor unprotected. For reliable safety operation, genuine OEM is strongly recommended.

Install Difficulty

Moderate — Involves working near sealed refrigerant lines and low-voltage wiring. Improper handling can release refrigerant or damage the port. Recommended for a licensed HVAC technician.

Disconnect power before servicing and confirm the part matches your unit's model and serial plate.
