Oxbox sen02528 Flame Sensor

Product Description

The OXBOX sen02528 is a replacement flame sensor designed for use in gas furnaces. The flame sensor monitors burner operation by detecting the presence of an ionization current when the burner flame is established. If no flame is detected, the control board shuts off the gas valve to prevent unburned fuel from accumulating. This part measures 4.75 inches in length and weighs 0.13 pounds, making it a compact, direct-replacement component. It is typically installed by a licensed HVAC technician during routine furnace service or as part of a no-heat diagnostic repair.

This flame sensor is suited for residential gas furnace applications where the original sensor has failed, corroded, or is causing nuisance lockouts. Flame sensor degradation is a common cause of intermittent heating faults, and replacement is a standard corrective action during a no-heat service call. The part fits into furnace burner assemblies where the sensor rod mounts in the path of the burner flame.

Installation Notes

Installation should be performed by a licensed HVAC technician. Shut off power to the furnace at the disconnect switch and turn off the gas supply before beginning any service work. The sensor rod must be positioned correctly in the path of the burner flame for accurate ionization detection.
