Color coordinating wire groups make it easier to identify the wire groups during reassembly. Inside the device, there are three junctions with wires joined by Phillips-head screws. The first is connected to two wires, and the other two are connected to three wires each.

Using a pair of pliers, bend the spring latch from a "[" shape to a "c" shape so that it fits through the silver-colored latch that holds it. Then pull the silver-colored beam up so that it detaches from the brass beam.

Carefully turn the device over, either allowing the hotplate portion of the device to fall out, or catching it as it falls out. For the next step, make sure the hotplate portion of the device has its flat side facing down.

Remove the 47 mm by 30 mm spring, by pulling it up and off the locking latch.
  • Remove the 47 mm by 30 mm spring, by pulling it up and off the locking latch.

  • If the spring is in multiple pieces, does not compress and spring back easily, or otherwise does not behave like a spring, you will need to replace it.

  • To reassemble your device, follow these instructions in reverse order. The two silver latches will need to be bent outwards separately, and the brass latch will need to be bent back into a "["or "(" shape by holding the pliers to a 90 degree angle of that in the instructions.
