Description
The Rheem-Ruud 42-106209-01K Dual Pressure Switch Assembly is a safety control part used in gas furnace and packaged heating systems to monitor airflow and combustion pressure conditions. It contains two internal pressure switches that operate in response to changes in draft or inducer motor operation, ensuring the burner only operates under safe airflow conditions. It is installed in heating equipment where it verifies proper venting, and combustion air movement before allowing ignition or continuing burner operation. By detecting abnormal pressure conditions in the system it helps prevent unsafe combustion supports reliable startup sequencing, and maintains overall safety and efficiency in heating applications.
