Within a few minutes of switching on the fuse blows - until that moment
the element heats up and the on-lamp is lit. The circuitry looks pretty
simple, a heating element, a thermostat and a power on lamp in parallel.
Is there an easy way to determine which part(s) are at fault, other than
replacing them one by one?
Thanks in advance
I suspect the element maybe breaking down when it gets hot, possibly
shorting to earth.
Some bimetal thermostats have a small heating element inside. This could
have failed in some way such that when the contacts first open, the fuse
Run the heater without the thermostat in circuit for a short while and
see if the fuse still blows.
