Peerless G-561 dosn't stay lit

Snips Member Posts: 4
Hey I am having issues with my Peerless G-561 1991, it will not say lit.  I have replaced the thermocouple with a 24" Universal Thermocouple however that did not fix the issue.  Any advice would be greatly appreciated.  If you need more information please ask.

    pilot problems

    what sort of pilot control valve is on the boiler? is the thermocouple in the flame well enough to get hot? is it firmly screwed into the control?

    do a search for thermocouple here, and there will be a list of tests to perform with a multimeter to check out the thermocouple.--nbc

    I have provided a few pictures hoping they can answer you questions.  If I hold the switch on it will keep the gas flowing however it will not stay open itself.

    Looks like the thermocouple isn't getting hot.

    I see the silhouette of the thermocouple against the center of the flame, but it isn't glowing red, and it doesn't look like the flame is wrapping around it. See if you can push it back a little so it's right in the flame.
