Description
The 790-956A1 flame sensor is a replacement flame rod designed for use in gas-fired furnaces and heating systems. This component plays a critical safety role by detecting the presence of a burner flame and sending a signal to the ignition control board to keep the gas valve open. If the flame is not detected, the system will shut down to prevent unburned gas from accumulating. This sensor is constructed with a durable high-temperature metal probe and an insulated base to withstand repeated heating cycles. It mounts directly to the burner assembly and connects to the control board through a single-wire lead, making it a straightforward replacement for worn or faulty sensors causing ignition failure or intermittent operation.
Key Features:
- Direct replacement flame sensor (flame rod) for gas furnaces
- Confirms burner flame presence for safe system operation
- Helps resolve ignition lockouts and flame sensing issues
- High-temperature resistant probe construction
- Single-wire connection for simple installation
- Mounting bracket included for secure fit
