how can i fix my potterton suprema boiler?
Help i have an ongoing problem with my boiler in that the thermister keeps failing i have had the boiler checked by a corgi registered engineer but no obvious fault can be found all resistances and voltages are correct. The thermister has been replaced about 8 times and after about a month the radiators get very hot and then the heating ceases to work, then we know the thermister will require replacement the engineer checks the system no faults are found and a replacement thermister is fitted all works ok for about another month Anyone have any ideas as this is driving me nuts!!
