Worcester Electrode Set 8716121817

The Worcester Electrode Set 8716121817 is the latest manufacturer replacement for obsolete part numbers 87186643010 and 87181070890. It contains the ignition and flame sensing electrodes required to ensure reliable boiler ignition, stable flame detection and efficient burner operation.

Over time, electrodes naturally wear through repeated ignition cycles. Consequently, your boiler may develop ignition faults, flame failure lockouts or unreliable burner performance. Replacing the electrode set helps restore dependable operation and improves ignition reliability.
