Hello everyone,
Currently I am trying to repair my air conditioner's DC motor.
the aircon is 12LGC and the motor model is MFE-40 VVL.
but this is not important.
I have opened the DC motor and looked on the PCB inside. There is 2 ICs and several resistors, capacitors and... one diode.
Outside the diode looks good, there is no physical damage, but has over 4MOhm resistance in both directions -> it should be replaced.
The diode is marked only as "20" and I cannot find what is it.
Is it a zener or shottky?
I have made a picture of it and attached the scheme. May be someone familiar with electronics can guess and suggests what kind diode I should use.
