OEM vs. Generic

Pressure switches are calibrated safety devices — an incorrect set point can cause nuisance lockouts or, worse, allow operation under unsafe venting. This OEM switch is factory-calibrated to Goodman's exact -.30/-.75 specification. Generic switches rarely match both set points, so OEM is strongly recommended.

Installation

Difficulty: Moderate (3/5). Requires disconnecting two hoses and wiring harnesses in the correct orientation. Shut off gas and power first, and verify tubing routing matches the original. A licensed HVAC technician is recommended for safety-critical controls.
