9 Failure and analysis Note: When replacing the controller, make sure insert the wire jumper into the new controller, otherwise, the running indicator off 3s, blink 15 times, (the dual eight will display C5) but cannot turn on the unit. The breaker trips at once when it Measure insulation resistance to ground to see if there is any leakage. is set to "ON". Trip of breaker or blow of fuse The circuit or the part of the air conditioner has malfunction.
Improper set of temperature Adjust set temperature If cooling (heating) load is proper Check the forecasted load of cooling (heating) The refrigerant has leakage or is insufficient Malfunction of refrigerant flow Leakage between the high pressure and the low pressure inside the compressor Malfunction of four-way valve Poor COOL(HEAT) operation Local block of capillary Blockage of cooling system Heat insulation for the connection pipes of the indoor unit and the outdoor unit is bad.
The indoor fan motor is burned or breaks or has the heat protector malfunction. The fan does not run when it is set to supply air. In the cooling and heating mode, the compressor runs, but the outdoor fan does not run. The compressor is too hot and leads to the action of the protector. The built-in heat protector of the motor breaks frequently because the motor is abnormal. Replace the fan motor Wrong connection Make the correction connection based on the circuit drawing.
Drainage pipe blocked or broken Change drainage pipe Water leakage Wrap of refrigerant pipe joint is not close enough. Re-wrap and make it tight. Fan of indoor unit contacts other parts. Adjust fan location. Foreign object in indoor unit Take out the foreign object. Compressor shakes too much. Abnormal sound and shake Adjust support washer of compressor, and tighten loosen screws. Touch of pipeline of outdoor unit Separate the touching pipeline. Touch of inner plates 1. Tighten connect screw.
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) 6.
