9-4. Trouble Diagnosis of Fan Motor 9-4-1. Outdoor Fan Motor This outdoor DC fan motor contains an internal control PCB. Therefore, it is not possible to measure the coil resistance, and the following procedure should be used to check the motor. Perform the trouble diagnosis by Test Run mode described on Installation Instructions. Important: (A) Turn OFF the power before connecting or disconnecting the motor connectors.
9-5. Noise Malfunction and Electromagnetic Interference An inverter A/C operates using pulse signal control and high frequencies. Therefore, it is susceptible to the effects of external noise, and is likely to cause electromagnetic interference with nearby wireless devices. A noise filter is installed for ordinary use, preventing these problems. However, depending on the installation conditions, these effects may still occur. Please pay attention to the points listed below.
10. CHECKING ELECTRICAL COMPONENTS 10-1. Measurement of Insulation Resistance Ground wire Clip The insulation is in good condition if the resistance exceeds 1M ohm. Probe 10-1-1. Power Supply Cord Clamp the grounding wire of power cord with the lead clip of the insulation resistance tester and measure the resistance by placing a probe on either of the two power wires. (Fig. 1) Then also measure the resistance between the grounding and other power terminals. (Fig. 1) Fig.
10-2. Checking Continuity of Fuse on PCB Ass'y Fuse Remove the PCB Ass'y from the electrical component box. Then pull out the fuse from the PCB Ass'y. (Fig. 5) Check for continuity using a multimeter as shown in Fig. 6. PCB Ass'y Fig. 5 Fuse Fig.
