The Goodman 0130M00075 Low Pressure Switch is a genuine OEM safety control for the APH1543M41BA heat pump. It monitors suction-side refrigerant pressure and opens the compressor circuit if pressure drops too low — the classic sign of a refrigerant leak, loss of charge, or restricted flow. By cutting the compressor before it runs low on refrigerant, this switch prevents overheating, oil starvation, and costly compressor failure.

Specifications

Function: Low-side (loss-of-charge) pressure switch
Action: Opens on low suction pressure, auto-resets when restored
Application: Goodman/Amana heat pump refrigerant circuit
Compatibility: APH1543M41BA (confirm setpoint against your unit)
Fit: Direct OEM replacement

OEM vs. Generic

A genuine Goodman OEM low pressure switch is factory-calibrated to the correct cut-out pressure for this system. Aftermarket substitutes with the wrong setpoint can either nuisance-trip in cold weather or fail to shut down a low-charge system, defeating the protection entirely. For a compressor safety, OEM calibration matters.

Installation

Difficulty: Moderate. The switch ties into the low-side refrigerant circuit. Many units use a Schrader fitting so charge recovery isn't needed, but always verify the port type, cut power, and follow the wiring diagram. Brazed-in switches require professional refrigerant recovery. Best handled by an HVAC technician.

How do I replace the pressure switch on my Goodman APH1543M41BA — 0130M00075?

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.
