yet another NPS45 error lights post

[celticpiping]

ok, I've been wrestling with this @#$% Napolean NPS45 free-standing stove for a year+
and it's still not working.

Had a stove expert in to look at it week ago, and he found it pretty well cleaned out, he finished up the last cleaning of it, and troubleshot the issue which is the classic :
You start the stove, it gets a nice looking fore going, and it then stops feeding, and the lights are #2 flashing, OR #1 solid + #3 flashing

He told me the vacuum switch was bad (even though I had done the 'suck test' and it sounded ok to me)
All excited, I buy a new one, and the stove acts very much as it did before:

1) Start it
2) It builds a fire in the pot
3) Right as soon as the stove switches to the exhaust blower, the lights flip to #1 solid, #2 flashing

I'm ready to chew my arm off....
I've gone through all the stuff in the manual...
doors tight, stove clean, air flow back the vacuum path is clear.. etc

Thoughts?

I don't know anything about your stove but after reading your post I had a thought that might be helpful. Are you sure you have a good power source? I would double check to make sure that it's plugged in to a properly grounded outlet and that there isn't some kind of fault such as an open ground or ground loop condition. If using a UPS I would remove it to make sure it's not introducing a problem that might be caused by less than a pure sine wave.

Interesting thought... it's plugged into 115 directly, independent from any strip/UPS etc...
And while I cannot vouch for the 'purity' of the sine wave, all in all, the electrics seem to be in order in this house(no old/outdated equipment in place)

Thanks !

Hmm... that may be your problem. No surge protection so any variation of electric current coming in may have damaged the board. Did you call the expert to explain it was not a vac switch? What was his next suggestion?

thanks!
