Goodman 0130M00074 High Pressure Cut-Off Switch

The Goodman 0130M00074 is a genuine OEM high-pressure cut-off switch for the WPH4342AHAB packaged unit and compatible Goodman/Amana systems. Wired into the compressor control circuit, it monitors refrigerant discharge pressure and opens the circuit to shut the compressor down if pressure climbs to an unsafe level — protecting the compressor from damage caused by a dirty condenser coil, blocked airflow, or overcharge. It resets when pressure returns to a safe range.

Specifications

OEM part number: 0130M00074
Type: High-side pressure safety cut-off switch
Function: Opens compressor circuit on overpressure, auto-reset on recovery
Fits: Goodman WPH4342AHAB and cross-referenced models
Factory-calibrated trip and reset set points

OEM vs. Generic

Because this is a safety device, the trip and reset pressures must match the system's design. The OEM switch is factory-calibrated to the correct set points and connects with the right fitting and terminals. Generic switches may trip at the wrong pressure, causing nuisance shutdowns or, worse, failing to protect the compressor. Always use OEM for pressure safety controls.

Installation Difficulty

Moderate. The switch mounts to a refrigerant service port and wires into the control circuit; some replacements require recovering refrigerant. Best performed by an EPA-certified HVAC technician. Estimated time: 30–60 minutes.

How do I replace the pressure switch on my Goodman WPH4342AHAB — 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.

Is this pressure switch compatible with Bryant or Payne too?

Many Goodman parts are cross-compatible with Bryant and Payne since all three brands are manufactured by Carrier Global Corporation. The same physical part is often used across brand labels with different model numbers. To verify: check your Bryant or Payne equipment service manual for cross-compatible part numbers, or email info@nationalhvacparts.com with your model number.

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

OEM recommended for reliability and warranty compatibility. OEM parts match exact factory specifications for proper fit, performance, and safety. While aftermarket alternatives cost less upfront, the risk of improper fit and reduced lifespan usually makes OEM the better value long-term.
