(2) If the self-diagnostics function fails to operate Check the indoor unit. Is the fuse blown? Replace the controller. Replace the circuit board or the fuse.
8-3. Checking the Indoor and Outdoor Units (1) Checking the indoor unit (2) Checking the outdoor unit (3) Checking the serial communications Using the TEST/T-RUN terminals Control No. Check items (unit operation) T -RUN : T est run (compressor and fan motor turn ON).
[T rouble symptom 3] Motor rotates for some time (several seconds), but then quickly stops, when the indoor unit operates. (There is trouble in the system that provides feedback of motor rotation speed from the motor to the indoor unit controller .) [T rouble symptom 4] Fan motor rotation speed does not change during indoor unit operation.
8-5. Noise Malfunction and Electr omagnetic Interf erence 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.
