Product review (5 stars): Stator Phase Resistance Measured Within Specs But One Shorted Coil Was A Game Stopper.
Great price.  I replaced the PCB only to find that the stator had a bad coil with the windings shorted inside the coil.  Problem was that all phases measured specified resistance and it appeared undamaged.  A friend with more experience in DC brushless motors saw the motor attempt to spin the drum but only oscillated a bit and stopped with no error code.  He showed me his instrument to measure the flux of a coil and he found the problem in less than five minutes.  Guess I need to buy one more test instrument for Checking Shorted Coils.
