0130M00089SP – HIGH PRESSURE SWITCH

Refrigerant-side high pressure cutout switch for Goodman / Amana equipment. It is a safety device in the 24 V control circuit: contacts open when discharge pressure climbs too high – dirty condenser, failed condenser fan, or overcharge – shutting the compressor down before damage occurs. Goodman publishes no spec sheet, so no cut-out or cut-in pressure is listed; read them off the switch body.

Specifications from our own stock records. The manufacturer does not publish a public page for this item.

Before you order

Worth knowing: this is a heat pump part. The matching straight-cool condensers (GSX130241, GSX140241, GSX160241) do NOT use it, so it is not a blanket fit across all Goodman outdoor units. Published application data. Always match the full model and serial number on your unit before ordering.

What do the two numbers on a high pressure switch mean?

610/420 means the contacts open when high side pressure climbs to about 610 psi and close back once it falls to about 420 psi. It sits in the 24 volt safety string, so when it opens the compressor stops. Some are auto reset like that. Others are manual reset with a button you have to push before the unit will run again.

Mine tripped. Does that mean the switch is bad?

Almost never. Put gauges on it. A properly charged R-410A system runs roughly 400 to 450 psi on the high side on a 95F afternoon, and around 445 to 490 psi at 105F. To get all the way to 610 something real is wrong - a condenser coil packed with grass clippings and cottonwood, a condenser fan that is not turning, an overcharge, or a restriction. Fix the cause and the switch quits tripping.

Why does mine only trip in the afternoon?

Head pressure tracks outdoor temperature and how well the coil can dump heat. A unit that is fine at 88F in the morning can hit cutout on a 105F August afternoon, especially if it is boxed in by a fence or blowing its own hot discharge air right back through the coil. Clean the coil from the inside out and give it clearance on all sides.

Can I jumper it out until I get to the real problem?

Do not. It is the last thing standing between a fixable problem and a dead compressor.
