- Method of error detection an electrical box temperature rise is detected by checking the radiation fin thermistor with the compressor off 107
- Short circuit 107
- Supposed causes 107
- The error is cleared when the radiation fin temperature drops below b c 107
- To cool the electrical components the outdoor fan starts when the radiation fin temperature rises above c c and stops when it drops below b c 107

- Check no 1 disconnect the connectors of the thermistors from the pcb and measure the resistance of each thermistor using tester the relationship between normal temperature and resistance is shown in the table and the graph below 112
- Thermistor resistance check 112
- When the connector of indoor heat exchanger thermistor is soldered on the pcb remove the thermistor and measure the resistance 112
- When the room temperature thermistor is directly mounted on the display pcb remove the display pcb from the control pcb to measure the resistance 112
- Check no 1 measure the power supply waveform between no 1 and no 2 on the terminal board and check the waveform disturbance 113
- Check no 2 1 check the connection of connector 2 check the motor power supply voltage output pins 4 7 3 check the motor control voltage pins 4 3 4 check the rotation command voltage pins 4 2 5 check the rotation pulse pins 4 1 113
- Check to see if the power supply waveform is a sine wave fig 113
