Air Con Cannot Turn On
If the air conditioner unit is stopped and then started immediately again, the compressor may not operate for about 2 to 3 minutes. Whenever the power to the air compressor unit is interrupted, the protection circuit prevents the unit from re-start for several (2-3) minutes when power returns.
This is the built-in function of the protection circuit to prevent fuse blow out due to the electricity surge when power turns off and on immediately.
