Mend Glow-worm Ultimate 50FF Boiler Heating Fuse

Glow-worm ultimate 50ff ?

worked fine for 20 years, now keeps blowing 1amp fuse on pcb. is pcb at fault.....or could it be something else.

the fans are prone to sticking. try greasing/cleaning it. the extra power to start a sticking fan usually blows fuses on pcb

usually caused by a faulty solenoid on the gas valve
