The stove gets dangerously hot at the back of the unit. I can't touch the top of the control panel it is that hot when I use the oven??

The LG LREL6323 Series stove can get dangerously hot at the back and control panel when using the oven because the oven vent is located above the left rear surface unit. This area becomes hot during oven use due to the release of hot air and steam. Blocking the vent or placing heat-sensitive items near it can increase the risk of burns or fire.

Why does oven get so hot at the very top of the stove

1 comments:

Mr. Anderson

August 25, 2025

The LG LREL6323 Series oven gets hot at the top of the stove because heating elements can remain hot even if they appear dark, and interior surfaces of the oven become hot enough to cause burns. This heat can transfer to the cooktop above.
