01. Cooling fan
Abnormal noise, even oscillation may take place if the fan have wearing
bearing, aging blade, here replacement of the fan should be considered.
02. Filter electrolyte capacitance
When frequent-changing load causes increasing pulsant current and aging
electrolyte under high ambient temperature, the electrolyte capacitance may
be damaged and here should replace it.
