The Goodman 0130M00074 is a genuine OEM high-pressure cut-off switch for the APH1436H41DE heat pump and compatible Goodman/Amana condensing units. This safety control monitors refrigerant discharge pressure and opens the control circuit if pressure climbs to an unsafe level — protecting the compressor from damage caused by a dirty condenser coil, overcharge, or failed fan. It automatically resets once pressure returns to a safe range.
The genuine Goodman OEM switch is calibrated to the factory trip and reset set points for your system's refrigerant and design pressures. Generic switches may cut out at the wrong threshold, causing nuisance trips or — worse — failing to protect the compressor. Choose OEM for correct safety-rated performance.
Easy (2/5). On a Schrader-fitted port the switch threads on without recovering refrigerant; hard-wired versions require brazing and evacuation. Most swaps take 20–30 minutes. Disconnect power and confirm the correct port before servicing.
