Choosing and fitting
When selecting a replacement switch of this type, ensure the contact configuration, pitch, and keying match the original. The number and arrangement of tabs must correspond to the existing wiring harness. Verify the electrical rating is suitable for the voltage and current in the circuit. The insulation temperature class should be appropriate for the environment inside the appliance cabinet, especially near heat sources.
Signs of failure
Connector faults, including those in switches, can cause intermittent electrical issues in boiler and burner systems. Symptoms may include erratic flame detection, fan run-on, lockout without obvious cause, or complete failure to start. These can mimic a faulty control board, broken sensor, or safety chain interruption. During fault finding, test the continuity and contact resistance of the switch before replacing more expensive components.
