This component RSN310R36 audio power module is overheating (40-45 degree Celsius). The fan at the back is not continuously working so this component gets overheat. Simple solution is to get a 12 volts power supply and connect the fan together. This will lower the temperature of the RSN310R36 (audio power module). Or if you really want to improve the temperature inside is add extra computer cpu fan. Either drill the top cover and place the fan directly to the component and heatsink. Like what I did. Good luck.
Heat? Generally speaking, an amp protects itself from heat, shorts and overloads by refusing to turn on or stay on. Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up. You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it. If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good. If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech. Check for loose speaker connections as a root cause for intermittent shutdown.

My set produced clicking sound and 'OVERLOAD' displayed just after it was switched on and without any speakers attached to it
