Overview

This is the OEM pressure switch assembly (part 1188015) for the Tempstar TVH848GKA101. The pressure switch is a safety device that confirms proper draft and airflow before the control board allows ignition and continued operation. It senses the negative pressure created by the inducer and closes its contacts to prove venting is clear. A failed or stuck switch will block ignition, cause short cycling, or trip the unit on a safety lockout — protecting the system from operating with a blocked flue or failed inducer.
