Common Service Questions:

Is the 550002068 compatible with older Utica models originally using 2272133?
Yes, the Utica-Dunkirk 550002068 is the official manufacturer-designated superseding part for the 2272133 ignitor, ensuring full electrical and mechanical compatibility.

What causes a hot surface ignitor to fail prematurely?
Most failures result from surface contamination—such as oil from fingers during installation—or cracks caused by excessive vibration or thermal fatigue. Always handle the silicon element by the ceramic base.

Can I test this ignitor with a multimeter?
Yes, technicians can verify the health of the hot surface ignitor by checking the OHM resistance across the leads; an "open" reading typically indicates a fractured element requiring replacement.
