: : Changing the pressuretrol would solve the problem of having too high a pressure if it actually controlled the burner, which it is supposed to do. Setting the control to 2 psig means that the burner should shut off at 2 psig; but, it didn't and doesn't, so changing the pressuretrol was not the answer. As the new pressuretrol would disconnect the power to the burner if it was subject to the boiler pressure, either the wiring that sends power to the burner is not passing through the control so burner power can be disconnected when the pressure gets to 2 psig
: : AND/OR
: : the tube that connects the pressuretrol to the boiler is clogged and should have been changed.

thamks for the reply but on changing the pressurtrol I inspected the pigtail on the pressuetrol and there seem to be no build up of rust or sediment can that go still be faulty. also on the wiring issue while boiler in running mode I disconnected the two wires to pressurtol and boiler shut down , so i still baffled on this
