Hi,

One day, when i try to start the air con, on heating mode, it burns out the thermal fuse, when I opened the electric panel i found this.

I would like to show how looks the ACTPM of my Fujitsu air con:

Please advice me, what cause this damage, and does it mean, that there is other damages.

Can you give me information, which kind is this burn out component, and its specs.

Thank you in advance.

A number of things can cause the damage including faulty compressor, IPM, diode block, main PCB wiring rubbed through. Hard to diagnose exactly but diode block, compressor and IPM can be tested to some degree with a meter.
I'd be meggering compressor and testing the parts mentioned and see what comes up then.

Not sure what the exact component is but not a serviceable part, damage like that normally caused when something shorts out or shorts to earth.

Cheers,
Andy.
