Hi I understand how it can be difficult to decide what might be causing problems on Gledhill units controlled by either the GT155 or GD131 control board so I have made a You Tube video which shows what to look out for and to check to try to help you decide where the fault lies.  I hope folks find it useful.

As always please remember that these pcb's have mains voltages present on them so care must be exercised and as always if you are not sure please consult a professional.
