Hi Bob...sorry you're having trouble..I'll do my best to help...
Can you see spark through the sight glass?
No, the glass is not clear so I can't see if there's spark.
Ok...here is what I do sometimes...very important...TURN GAS OFF!! Then remove the spark ignitor from the burner plate... ground it to the burner plate with a wire (I have jumper wires with alligator clips)..then with GAS OFF.... try to run the boiler..see if you have spark..
If you don't have spark..then then you have a bad ground,, too wide of spark gap... loose ignition wire connections or a bad spark module.
We've got spark
Ok..that's a good thing...are you on LP or Natural gas?
Ok...you can replace the ignitor..(if you haven't)...... do you hear the gas valve click during the ignition cycle?
Also..I believe you told me that you cleaned the flame sensor correct?
just put it back and it started up and ignited. looks like all is good
Great! Is there a green light on the 925 controller?
That is your 'proof of flame' indicator...
Sounds like it must have been a crummy connection somewhere
I can see the flame thru the window now too and the temp is rising rapidly
Good deal...as I said...rarely do you have to actually replace the probes unless you damage the insulator removing it.
Terrific. Thanks, Tom!
I guess just double check all wire connections to make sure everything is tight and ground wires are tight.
No problem....one of those...not sure what we did but it must have been a connection things!
It happens more than you'd like to admit
Thanks for the accept
You're welcome. It was worth my money to get your help - especially on a cold weekend. Bob

Old age getting to me I think!
(your money is deposited into Justanswer account..I do not recieve credit until you accept)
Hi Bob...sorry I missed you ...I forgot I had the ACCEPT ANSWER key disabled. I usually do that until we solve a problem. I forgot to unlock it so you accept did not go through.
You deposit remains on account with Justanswer until you accept at which time I'll recieve credit. If you can log back in and accept when you have time I'll appreciate it!
Sorry..my fault! Tom
