Nordyne 1023973R Dual Pressure Switch Overview
The Nordyne 1023973R is an OEM dual pressure switch engineered for reliable, safe operation in Nordyne heating systems. Featuring dual setpoints of .80″ and .40″ W.C. (water column), this switch monitors both positive and negative pressure conditions within the furnace’s venting and combustion air system, helping to prevent unsafe operation if proper airflow is not established.
Key Features
- Dual pressure switch with .80″ W.C. and .40″ W.C. setpoints
- Monitors combustion air and venting pressure for safe furnace operation
- OEM Nordyne replacement part — ensures proper fit and function
- Designed to work in conjunction with the draft inducer blower circuit
- Helps protect against incomplete combustion and unsafe venting conditions
- Direct drop-in replacement for compatible Nordyne furnace models
How It Works
The dual pressure switch verifies that the draft inducer motor is operating correctly and that adequate airflow is present before allowing the furnace ignition sequence to proceed. If pressure falls outside the specified setpoints — either at .80″ or .40″ W.C. — the switch opens the control circuit, shutting down the ignition sequence and protecting the system from hazardous conditions such as flue gas spillage or blocked venting.
Application
- Compatible with select Nordyne gas furnace models
- Ideal for service technicians performing OEM-quality repairs
- Recommended for use with Nordyne, Frigidaire, Tappan, Gibson, and other Nordyne-branded furnace lines
