He 2 ignition failure

Aran_skates_1

Have an he 2 30 years old failing to ignite but periodically igniting. 
 Control,gas valve, rollout are original.     
Transformer igniter(new style honeywell) are new   Here's what's going  on.

1.   Goes through cycle up to igniter.    So.etimes it glows sometimes it doesn't.

2.    If it glows the gas valve will open.
2a.   Sometimes the gas valve will close.              before it ignites.
2b.     Sometimes it stays open and the flame will ignite

3.    This seems to have started after a few poweroutages where the boiler. COoled down and was leaking drops from the dielectric down near the igniter.   It didn't appear to be leaking on the control.

4.    I replaced the hot surface igniter with a new honeylwell igniter 

5 .   If it fires and runs it seems to run fi e until it's no longer ger calling for heat and then goes back to step 1.

Does this boiler have a flame sensor that may be malfunctioning?
Bad gas valve?
Bad control?
Something else?

Also my pressure is running at 28 psi which seems a little high right?

Thanks in advance

sorry can you be more specific what you mean? Do you mean like on the terminals of the different components?

neilc

wire connections need to be clean and tight,
any chassis mount screws need to clean and tight,
power goes out, and needs to get back,
anything that got wet is suspect,
any electronics that got wet gets replaced,

this only started after things got wet with the outage?

and yeah, 28 is getting to close to blowing off the 30,
