The Goodman 0130M00075 is the OEM low-pressure switch for the APH1524M41AB packaged heat pump. It monitors refrigerant suction pressure and opens the compressor circuit when pressure drops too low — a condition typically caused by a refrigerant leak, low charge, or restricted flow. This protects the compressor from running dry and overheating. If your heat pump won't start or trips out shortly after starting, a failed low-pressure switch may be to blame.
The OEM 0130M00075 carries the precise low-side setpoint Goodman engineered for this unit. Generic replacements may cut out at the wrong pressure, causing false lockouts or leaving the compressor unprotected. Choose genuine OEM for dependable, correctly calibrated protection.
Easy to moderate. Quick-connect versions swap in minutes; brazed or Schrader-mounted versions require an EPA-certified technician for refrigerant handling. Always kill power before servicing.
