Sony Sony STR-AN1000 7.2-Channel AV Receiver with Dolby Atmos OVERHEAT Error Fix: Receiver Overheating

Error code OVERHEAT on the Sony Sony STR-AN1000 7.2-Channel AV Receiver with Dolby Atmos means: Receiver Overheating. The receiver chassis is excessively hot to the touch, the receiver may shut down unexpectedly, or audio quality may degrade due to thermal throttling. AV receivers with 7 or more amplification channels generate substantial heat during normal operation, especially when driving speakers at moderate to high volume levels. Ensure at least 4 inches (10 cm) of clearance above the top of the receiver for heat dissipation — heat rises and a blocked top vent is the primary cause of overheating. Provide adequate ventilation on all sides. Do not stack other AV equipment directly on top of the receiver. Do not place the receiver inside an enclosed media cabinet without active ventilation — consider adding a quiet cabinet fan. If operating in a room with high ambient temperature, reduce the volume or limit continuous high-volume playback. The receiver internal thermal protection circuit will shut the unit down automatically if internal temperature exceeds safe limits.
