Hello, My name is XXXXX XXXXX I will do my best to assist your issue.
Are you able to observe the HIS (glow plug)?
HSI = Hot Surface Ignition
ok, do you know when it was the last time this may have been replaced?
the furncae was installed fall of 1999. it's in the same condition as it was purchased.
Typically the HSI can go bad and only light the burners intermittently. This can sometimes be visible if it has a small hairline crack
what does HSI look like?
While observing the HSI, sometimes there will be an abnormal wear
that is the glow plug
duh, sorry Im so uninformed
no it's ok really
that is why I / we are here.
Is this our problem? Anything else to say
The true way to know if that glow coil is bad would be to ohm it out. But, the downfall is knowing what the OHM reading should be.
It very well could be the issue.
I think that an OHM reading approximately 5 ohms is a general number
I suspected this at the very first, but it worked....just didn;t know it was intermittent. Thanks!
Hearing the gas valvve click in the manner it is, informs us that it is opening
correct. Sometimes it will light the burners and sometimes it will not.
Generally an inexpensive part
and all it does is plug in. the biggest issue with changing them is you do not want to touch the glow coil itself, nor do you want to bump it on anything.
And the fact that it's getting the order to "click" means the control board is okay, yes?
in a matter of speaking yes. everything that you are explaining seems to be a normal sequence of operation
