| Typical Failure Modes | contaminated optical window, aged cell, damaged cable |
Choosing and fitting
When selecting a replacement photocell of this type, ensure the detection principle (light detection), cable length, connector type, and mounting dimensions match the original component. The sensor must be positioned with a clear line-of-sight to the flame, typically in a viewing tube or sleeve. Verify the mounting arrangement and spectral response to match the burner control.
Signs of failure
Common failure modes include a contaminated optical window, an aged cell producing a weakened signal, or a damaged cable or sheath. Symptoms may include the burner failing to start or shutting down during operation due to lack of flame confirmation. Check the optical window for dirt or damage, and test the sensor's output signal.
