"Tiny Cooling Fan" in the use of the process will inevitably encounter some failures, then experience a failure when the AC fans should be how to solve it? Next we will discuss with you about this issue. First, to reduce the exchange "Tiny Cooling Fan" of failure frequency is necessary prior to use full debugging, ensure AC cooling fans to run at its best. Secondly, the use of AC cooling fan is turned on to ensure its proper way, pay attention to observing the current size, stable current and voltage, time if insufficient grid capacity, you need to buck the way, so as not to communicate "Tiny Cooling Fan"have a negative impact.
