Why does my boiler fuse keep blowing?
The boiler is blowing up. Is that correct? The power should be turned back on if the transformer is ok. PCB will be faulty if it does and should be re-introduced one component at a time in order of operation. Transformer, pump, fan and external controls are used to see which one blows the fuse.
