Description
The Armstrong Furnace R102613-01 is an OEM two-stage pressure switch engineered as a direct replacement for compatible Armstrong Furnace systems. Designed to monitor and verify proper draft inducer operation, this pressure switch plays a critical safety role by preventing furnace ignition unless the correct negative pressure levels are confirmed within the flue and combustion air system.
How It Works
This dual-function pressure switch monitors two distinct pressure thresholds — .45″ W.C. and .80″ W.C. — corresponding to the two stages of furnace operation. On a call for heat, the switch confirms that the draft inducer has established adequate airflow before allowing the ignition sequence to proceed. If pressure falls outside the acceptable range at either stage, the switch opens the control circuit and locks out the furnace, protecting against unsafe combustion conditions.
