Installed on the suction (low-side) line, this switch opens the compressor circuit when suction pressure drops too low — the classic sign of a refrigerant leak or loss-of-charge condition. By cutting power before the compressor runs starved of refrigerant, it prevents overheating and bearing damage, then resets automatically once pressure recovers.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Part Number:\u003c\/strong\u003e 0130M00075\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Low-side pressure cut-out switch (normally closed)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApprox.

The OEM 0130M00075 is factory-calibrated for this Goodman unit, while generic substitutes often use different cut-in pressures that either nuisance-trip in cold weather or fail to catch a slow leak.
