Hi Guys,

Can someone please explain to me why DC condenser fan motors take out the outdoor
Control PCB when they go faulty?
Sometimes they check out fine on resistance readings. Is it something to do with the diodes in the fan motor?
I had one that was supposed to check at .5V DC and it was reading .001

And why do they take out the board even when it has not started up?

I'm no electronics expert, but why don't they have fuses to prevent this?

Thanks,
Keza
