Hi good day. A few days ago I acquired this sound plant, which during the last month and been using without presenting any inconvenience, but these days notice that the cooler that is installed in the back is not starting, check the status of the cooler with a source external and works normally. Make measurements on the cooler connector and mark 0.03 V, I request your cooperation with possible failures or how to repair this problem. Thanks in advance for reviewing my question.

Cordial greeting, friend if I check and discard the cooling fan and it is ok, it is well discarded if in the connection pins of the midio fan and it is in that low voltage, when they usually work mostly 12VDC if they are of 5 "and work with DC voltage must verify in the positive line where it arrives and through which it arrives, there may be an open resistance in that line or failing that a transistor type regulator that has been damaged can be a 7812 or similar If this fan works with AC voltage, it is necessary to see the fuses that are ok, I hope this contribution is of your help.

Hi. It would be necessary to see if the zone that activates it is fed. Is this activation with a relay or a power transistor? You mentioned that you bought it recently, you have no guarantee? regards
