Main Heat 12 boiler PCB is not responding

Hello Everyone,

My five years old Main Heat 12 boiler is behaving weirdly due to its PCB, which is not responding like from two-three days. Moreover, the display panel of the Main heat 12 boiler is not having the needed power. Someone please help me to get rid of this irritating problem.

Thanks a lot for kind Help and suggestions

Peter

Hi Peter,

PCB is considered as an extremely important and precious part of any boiler because the PCB manages and controls the different electrical devices. You cannot find the errors in your Main heat 12 boiler easily just due to number of things that are liable for this problem. The tested and recommended way-out is to seek advice from an experienced boiler engineer.Â
