Welcome to the forum. Although you can post in any forum, the USA forum is here in case of local regs or laws
I have re system boiler at the new house , boiler does not responded to thermostat knob and only cuts out on the high limit ..... thermistor reads 2.6 k ohms
high limit stats are on 0.5 ohms .... Burner pressure is 18.5 mbar
any one experienced this ?
in worse case the burner can lift causing melt downHave you checked the inner door seals? The red seal crumbles away and the fan limit stat trips, throwing the over heat light. The boiler might not actually be getting that hot for the control knob to work.
