51771u Question

I have a part #51771u ignitor for a Beckett burner, that stopped working after less than one year of service.

It's on a boiler used for heat and hot water in New England.

Any ideas to why it stopped working?

Ignitor

The most common cause for failure of the electronic ignitors, or so I've found, is incoming electrical problems. Grounding is critical as is a dedicated circuit to the heater. They also seem to hold up better when used for interupped ignition.

Thanks for the reply...

Pretty sure electrical is very good but will check.

What might I look for, as to problems that is?



Grounding is critical as is a dedicated circuit to the heater.

Circuit is definitely dedicated and grounded.


They also seem to hold up better when used for interupped ignition.

That one, can you explain what you mean?

One thing my lovely bride of 36 years this Tuesday asked was, "would lowering the temp at night cause problems, seeing as it is an eletrical ignitor?

Lovely Bride

Gotta give her credit for thinking about a possible connection, but the answer is no, at least not normally. If the boiler got cold & happened to leak water onto the ignitor, well maybe.

Interupped ignition: The easiest way to tell if the burner is set up with interupped ignition is to see if the burner motor black wire is tied to the ignitor's blue or if the ignitor is wired separately. If separate, it is interupped. If together it is intermittent.

Check all the wiring, especially the neutrals to make sure you have good connections. Another thing electronic ignitors don't like is heat. If the boiler reflects a good bit of heat onto the burner, this will cause premature failure. Of course it's possible you got a bad ignitor. It should be under warranty.
