Comfortmaker new style ignitors - anyone having problems like me??
 
This is a thread off of the other Comfortmaker not running question. The problem is that the new style ignitor, which I bought 2/21/08, does not light the pilot light (well sometimes but not on a regular basis).

The pilot orifice is clean. I unscrewed the ignitor/sensor/pilot assembly, removed the clip holding on the ignitor/sensor, turned on the furnace and held it infront of the pilot light. The ignitor was red hot and the gas was flowing but the ignitor would not ignite the pilot no matter where it was. I put a spark from a lighter infront of the pilot and it lite right up. The pilot flame was good and within the spec range stated in the tech support manual.

FYI - this is a replacement ignitor/sensor (MM-643KJ NITRD IGN ASSMB) which is different than the original (P/N 1009524 for a NUGM/GUK Series furnace), supposidly better. The original one burn out/quit working. I think I have to pony up and spend more money for the original type. Any ideas from anyone before I spent the $$?

Get the OEM part. The nitride don't get hot enough. I screwed with one for an hour til I gave up. Had to use OEM

Thanks for the info. I contacted the supply company I bought the assembly from and, since is has been less than a year, they are going to get me the original carbon type. They said it is a problem with that style furnace and the "smart valve".

Your WELOME:)

The valve does have it's problem but has nothing to do with your issues.

The nitride igniters from Supco just suck sewer water...bad design.

But I am glad i could help.:wink:

Igniter not hot enough
 
Had the same problem with round glo-stix after a year of use. Did some research on line. Chinese items do not get hot enough. I changed to flat ones and have not had any more problems.

if anyone knows how to know how to tell where they are made let me know. Where I bought would not reply to warranty questions.
