Main burner won't start. Heat and Glo 6000CIXIPIS

[babo]

hello,

my unit (6/10 yo I assume) was working 2 winters ago. After a pilot replacement and cleaning it worked for another year. And this past winter main burner stopped lightning up. Just in time for Christmas...

As of right now:
The pilot comes up right away.
Gas color is blue.
i cleaned the pilot just to be sure.
I also checked all wires - all seemed to be tight.
I vacuumed the main burner.
I replaced the ICI unit, but that didn't fix the problem.

Once i manually turn ICI into "ON" it clicks, turns the pilot on and clicks again. After that nothing happens no matter how long i wait.

I appreciate your guidance and time.

I would "rap" the solenoid housing on the gas valve with the plastic handle of a screwdriver.
That solenoid can "stick" after a couple of years.
It is in the 2nd pic with the black face & there is a harness attached to it.
Don't hit the black part. It's also plastic & can fracture. Make sure you hit the metal part...

Control unit, blocked burner orifice, or bad valve. Do you own a volt meter?

Magic. Ta-Da. worked after gentle, but consistent knocking on the metal part for about 15 seconds.

thank you so very much Bob!

Btw, do i need to be prepared to replace it soon ?

Glad it worked. I don't think you have to replace anything soon.
I've had a 6000TRX-I since 2004. I had to "rap" the solenoid once,
about 7 years ago, & it hasn't stuck since...
