The Goodman 0130M00074 High Pressure Cut-Off Switch is a genuine OEM safety control designed for the Goodman WGPH4536AMAB packaged air conditioner and compatible models. Wired into the compressor control circuit, this switch continuously monitors discharge-side refrigerant pressure and opens the circuit if pressure climbs to an unsafe level — protecting the compressor from damage caused by a dirty condenser coil, failed condenser fan, overcharge, or restricted airflow.

Specifications

Type: High-side pressure cut-off switch
Function: Auto-reset on pressure drop (factory-calibrated)
Circuit: Normally closed, opens on high pressure rise
Connection: 1/4 in. SAE male flare fitting
Terminals: 1/4 in. spade quick-connect
Fits: Goodman WGPH4536AMAB and compatible packaged units

OEM vs. Generic

This is the factory OEM part, pre-calibrated to Goodman's exact cut-out and reset set points. Generic universal pressure switches may carry different trip thresholds and connection styles, which can lead to nuisance trips or a switch that never protects the compressor when it should. For a safety-critical control, OEM is the recommended choice.

Installation Difficulty

Moderate. Requires disconnecting power, a Schrader-style or flare connection on a refrigerant port, and basic low-voltage wiring. Refrigerant handling on some configurations may require an EPA-certified technician. Plan 20–40 minutes.

How do I replace the pressure switch on my Goodman WGPH4536AMAB — 0130M00074?

Difficulty: Medium (20–30 min)
Step 1: Turn off power. Step 2: Locate pressure switch near draft inducer. Step 3: Note tubing orientation. Step 4: Disconnect tubing and wires. Step 5: Remove screw, install new switch. Step 6: Reconnect tubing and wires, restore power.

My furnace shows a pressure switch error. What do I replace?

Furnace LED showing pressure switch error = switch not detecting draft inducer airflow. Try first: clear the rubber tubing to the switch (often clogged with condensation). If problem persists, replace the pressure switch.

Should I use OEM or aftermarket for my Goodman pressure switch?
