Re: Understanding air conditioner PSU logic
I don't know how you checked E3 but I would replace it. If it is dried out (very likely) it will not charge to sustain the ic's vcc.
Check to make sure M1 is not shorted D~S, Also Check that IC8 (mosfet) on the module board is not shorted.
I will also ask again: Did you replace the module board and if not, what was shorted?
