Rheem-Ruud 62-23543-02K Flame Sensor

The Rheem-Ruud 62-23543-02K Flame Sensor Kit is a replacement flame detection component designed for compatible Rheem and Ruud gas-fired heating equipment. This furnace flame sensor monitors burner flame presence through flame rectification, allowing the ignition control system to verify that combustion has been established.

During normal furnace operation, the flame sensor generates a low-level DC microamp signal when exposed to the burner flame. If the ignition control board cannot detect an adequate flame signal, it may shut off the gas valve as part of the furnace's safety sequence.

The Rheem 62-23543-02K replacement flame sensor replaces part number 62-23543-02 and is intended for servicing compatible furnace ignition systems experiencing flame-sensing faults, intermittent burner shutdowns, or flame-proving problems.

This Ruud furnace flame sensor is designed for professional HVAC service applications. Before replacement, technicians should verify the equipment model number, sensor mounting configuration, electrical connection, and manufacturer parts documentation to ensure proper compatibility.

Common Questions

What does the Rheem-Ruud 62-23543-02K flame sensor do?

The flame sensor detects burner flame presence and sends a flame-proving signal to the furnace ignition control board. This allows the control system to verify proper ignition before continuing gas valve operation.

Can a faulty flame sensor cause my furnace to shut off?

Yes. If the ignition control cannot detect a sufficient flame signal, it may shut off the gas valve. Similar symptoms can also result from grounding problems, wiring faults, burner contamination, or ignition control issues.

Does the Rheem-Ruud 62-23543-02K replace part number 62-23543-02?

Yes. The 62-23543-02K is identified as a replacement flame sensor kit for Rheem-Ruud part number 62-23543-02.

Will this flame sensor fit my Rheem or Ruud furnace?

Compatibility depends on the exact furnace model, mounting configuration, electrical connection, and manufacturer specifications. Verify the equipment model and original part number before ordering.
