Overview

This OEM pressure switch assembly (part 1188015) is the factory safety control for the Tempstar TVA949GKA101 heat pump. The pressure switch monitors refrigerant or air pressure and interrupts the control circuit if pressure leaves safe limits, protecting the compressor and preventing damage. When the switch fails or sticks, the system may refuse to start, lock out intermittently, or short-cycle. The correct OEM assembly restores reliable safety operation and proper sequencing.
