The Goodman 0130M00087 Low Pressure Switch is a factory OEM safety control for DCC300XXX4BXXXAC packaged air conditioner systems. It monitors suction-side refrigerant pressure and de-energizes the compressor circuit if pressure drops too low — protecting against loss-of-charge conditions, coil freeze-ups, and the slugging that destroys compressors when charge runs low. Replacing a worn low pressure switch restores reliable freeze and loss-of-charge protection.
The OEM 0130M00087 ships with Goodman's verified low-side setpoints so the compressor cuts out at the correct suction pressure. Generic substitutes often carry different trip points and may not seat properly on the factory port, risking false lockouts or unprotected operation. OEM ensures the protection works exactly as engineered.
Intermediate. May require refrigerant recovery and certified handling of the sealed system, plus simple low-voltage wiring. Best installed by a licensed HVAC professional.
