The OEM 20197310 is factory-trimmed to -0.60 in WC, so it proves and releases at the pressures the Goodman control board expects. A mismatched generic switch (wrong set point or NC vs. NO) will cause lockouts or, worse, defeat the safety. Always match the -0.60 rating stamped on the original.\u003c\/p\u003e\u003ch3\u003eInstall Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eEasy–Moderate (2\/5).\u003c\/strong\u003e Remove the hose and two spade terminals, unscrew the switch, and reverse.
