After progressing beyond the locked door, you will move through an outdoor section before entering a room containing a Furnace. This part of the area requires you to activate the Furnace to advance further. Attempting to pull the cord immediately will not trigger any response, as the Furnace first needs to be fueled in Little Nightmares III.

Feeding the Furnace

To power the Furnace, coordinate between both characters. One player should hold the Furnace Door open while the other throws Coal inside. Continue adding Coal until the Furnace is filled. Once all the Coal has been placed inside, pull the cord to activate the mechanism. You will know the Furnace is ready when the dial on the left side moves into the red zone, signaling that it has enough fuel to operate in Little Nightmares III.
