Maintenance Plans for Daikin Indoor Unit Wall Mounted Type Air Conditioner Model FTX20KV1B
Integrate maintenance plans directly into your work orders in MaintainX.
Power Supply Waveforms Check
Warning: This check requires trained personnel with PPE!
Measure the power supply waveform between No. 1 and No. 2 on the terminal board
Is the power supply waveform a sine wave?
Upload a photo of the waveform
Is there waveform disturbance near the zero-cross?
Sign off on the power supply waveforms check
Indoor Fan Motor Connector Output Check
Fan motor wire breakdown / short circuit check
1. Check the connector for connection.
2. Turn the power off.
3. Check if each resistance at the phases U - V and V - W is 90 Ω ~ 100 Ω (between the pins; 12 - 9, and between 9 - 6).
Motor control voltage check
1. Check the connector for connection.
2. Check the motor control voltage is generated (between the pins 2 - 3).
Rotation pulse check
1. Check the connector for connection.
Rotation Pulse Check
Warning: This procedure requires trained personnel with PPE!
Set operation off and power off. Disconnect the connector S70 or S71.
Voltage between the pins 4 - 7
Control voltage between the pins 3 - 4
Rotation command voltage between the pins 2 - 4
Keep operation off and power off. Connect the connector S70 or S71.
Rotation pulses at the pins 1 - 4 when the fan motor is rotated 1 turn by hand
Fuse melted?
Outdoor fan motor functioning properly?
Power Module Check
Warning: Ensure the voltage between (+) and (–) of the power module is about 0 V before proceeding
Voltage check successful?
Disconnect the compressor harness connector from the outdoor unit PCB. To disengage the connector, press the protrusion on the connector.
Connector disengaged successfully?
Measure resistance between the terminals of the power module and the terminals of the compressor with a multimeter.
Enter the resistance measurement
Evaluate the measurement results
Sign off on the power module check
Thermistor Resistance Check
Warning: Disconnect the connectors of the thermistors from the PCB before proceeding
Thermistors disconnected from the PCB?
Measure the resistance of each thermistor using a multimeter
If the room temperature thermistor is soldered on a PCB, remove the PCB from the control PCB to measure the resistance
Room temperature thermistor removed from the PCB?
Measure the resistance of the room temperature thermistor
If the connector of indoor heat exchanger thermistor is soldered on a PCB, remove the thermistor and measure the resistance
Indoor heat exchanger thermistor removed from the PCB?
Measure the resistance of the indoor heat exchanger thermistor
