We had the same problem last year, system calls for heat..everything comes on and after 3to 5 minutes it shuts itself down. Last year the old Tech came out replaced the pressure switch and we were good. Same symptoms this year, old Tech no longer in business. I call a local reputable company and he comes out, not the pressure switch, not the aquastat, not the pump....He thinks the pipes are plugged and water isn't moving enough to cool down , so system shuts down. I pay the bill, I have no heat because he can't fix it.
My question is:
How can I tell if the pump is working? Manual says that the pump will continue after the blower and burner shuts down. How do I know this is happening?
It is a Crown Boiler, thanks
