Phil :

Hi,This is risky business, not responsible for damages on your end. We keep going until you're satisfied. I come and go. be patient

Phil :

Cause could be ignition failure or flame detection failure.. remove a service panel and observe the start up and tell me what you see or hear.

Phil :

we can go from there, Phil

JACUSTOMER-mboxm3ts- :

no startup issues. works fine for a while, sometimes days, weeks, then all of a sudden will throw an error code of 10. on push off, unplug, replug, turn on and wll works fine.

Phil :

Those intermittent problems can be virtually impossible to find.

Phil :

Do this, replug all the wiring gang connectors.. oxidize on a pin will cause this.

Phil :

then wait for it to fail..the problem is locatable that way

Phil :

it may never fail, the electronics may just have bugs..thats comon

Phil :

get back to me if you need to, we can go from there, otherwise hitting the accept button gives me credit, Phil

JACUSTOMER-mboxm3ts- :

this has already been tried to no success. how do you think it is locatable?

Phil :

I meant that when a system fails entirely.. wont run at all.. then finding which item is defective is not a problem.

Phil :

the failed item is locatable that way.

Phil :

If its failing intermittently.. then you check it and its OK at that instant.. you cant see that its actually going bad... same with electrical tests on some items.. they will test good on a meter, but fail at random under a load.

Phil :

Let me know if that makes any sense on your end, Phil
