I have a Utica MGB boiler whose pilot has gone out 50+ times over the last few years. We have replaced pretty much everything at least once including the pilot assembly, gas valve, & aquastat. We have installed the Johnson Controls K16RA thermocouple. We have cleaned out the pilot gas tube. The HWH on the same gas service works fine, as do the other boiler & HWH on the other service (2-family house).
Does anyone know of someone in the Albany NY area who has the expertise and will take the time to figure out the problem? I do most of the troubleshooting and repairs for the 22 boilers in my rental units and I have had a few guys in to work on this one but once it is running they are done.
Or do you have any other suggestions for me?
I contacted Utica suport and they suggested replacing the pilot assembly (which I did). I have read extensively here on HH about how to set up the thermocouple with 1/3 to half of it in the flame. The pilot flame seems robust when it is working.
EDIT I should add that replacing the pilot assembly seems to have solved most of the problems. It went out in Nov '18 and we replaced the 8 month old thermocouple, it went out again in March of '19 and we replaced the thermocouple with the K16RA, and it is out again today.
Thanks to everyone in the HH commmunity.
