Simple troubleshooting

(1) voltage, no order, the machine doesn't motor parts work. Is commonly Z301 varistor short circuit breakdown, insurance FU3OO fusing; Transformer primary winding. (2) the indoor fan did not electric vehicle motor turn. Check for + 12 v ICl02 pet-name ruby foot, attending, 11, 15 of which have a foot as the low level, the attending, 11, 12 of the ICl for a foot to high level. Check the fan capacitor ever exception; Fan motor winding is open (short wholesalemotor.blogspot.com circuit). (3) the outdoor fan does not turn, but the compressor operation. Generally fan cover for ICl or SWl or SW2 damage, fan abnormal capacitance. Fan motor winding is open circuit or short circuit.
