Arrived on site to diagnose no heat on propane boiler after an on call visit. After initial inspection we found that the pilot was lit but boiler would not fire. We found that the rollout switch was tripped. Reset it and boiler fired right up. We then cycled the boiler a few times to verify it was working properly. During one of the cycles, the pilot went out and we were unable to relight it. Removed pilot assembly and found that the thermocouple was loose. Pushed thermocouple back into assembly and relit. Stayed lit this time. Informed Zach that if this problem persists that the whole assembly will need to be replaced as the nut that was holding the thermocouple in place had melted inside the assembly and was not removeable without risking damage to the assembly itself. As of now, the boiler is operating and heating zones properly.
