PG motor locked protection H6:
Probable reasons:
1. Air vents were blocked which may cause the fan speed is too slow;
2. Fan blade locked;
3. Motor locked;
4. Fan motor capacitor damaged;
5. Motor damaged (ordors, winding, open circuit or shortcircuit are not normal, when testing the winding, pls distinguish
whether the motor body cause temperature is too high so that bring on the thermal protector starts up)
7. Mainboard damaged.
8. Motor thermal protection.
Disposal methods:
1. Remove the obstruction;
3. Replace motor;
5. Replace motor;
7. Replace mainboard;
6. Replace circuit board;
4. Replace capacitor;
2. Reassembling;
6. IC board damaged (during normally running, there are voltage at both capacity input and output)
8.Under the normal circumstances, the motor will not act, but in other circumstances, such as evaporator is very dirty, to much dust
attached on the fan blade that will cause the motor overload running, so that during the operation, frequent thermal protection will
happen, so it is need to be cleaned or replaced.
