Once finished, reconnect the speakers to the receiver.
Verify asolid speaker wire connectionbefore turning anything back on.
Assess Overheating
Most electronics have a built-in fail-safe to protect against overheating.
If it feels uncomfortably or irregularly hot to the touch, overheating is likely the cause.
A speaker with animpedanceof 4 ohms or fewer may be too low for the receiver you have.
You could alternatively install a small cooling fan inside the entertainment center to boost air circulation.
Avoid Direct Sunlight
Protect the receiver from sunlight.
Sometimes this solution can be as simple as closing the blinds.
Otherwise, you’ll want to move your receiver so that it’s out of the way.
Clean Excess Dust
Even a thin layer of dust acts as insulation.
Inspect the interior of the receiver through any open vents or slots.
If you see dust, use a can of compressed air to blow it out.
A small hand vacuum can help suck the dust out, so it doesn’t resettle elsewhere.
Check Current
Underpowered circuits are at risk of damage.
If a receiver is not getting enough current, it will turn itself off.
Plug the receiver into a dedicated wall outlet.
