Tempstar Pressure Switch Assembly for TVH860GKA101 — OEM 1188015 | Ships Today

Overview

This is the genuine OEM pressure switch assembly (part number 1188015) for the Tempstar TVH860GKA101 unit. The pressure switch is a safety control that monitors refrigerant or air pressure and shuts down the system if pressure moves outside safe limits, protecting the compressor and other components from damage. When the switch fails or sticks open, the unit will not start, locks out on a safety fault, or short-cycles. Replacing a faulty pressure switch restores normal sequencing and keeps the system's safety protection intact.
