Elmer's Glass Kiln manual Replacing the Temperature Controller, Replacing the Firing Chamber

Page 19

Place the new part next to the old one, aligned in the same direction. Re- move and replace one wire at a time. In the photo, the relay is being re- placed. The transformer is the part in the foreground.

4Hold the new part next to the one you are replacing, aligned in the same direction. Remove and transfer one wire at a time from the old part to the new one. Make sure each connection is tight.

5Replace push-on

connectors and wires damaged by heat from a burned terminal. If wire connectors do not fit snugly on terminals, gently squeeze the end of the terminal with pliers.

6As you move the sheet metal bottom back into place, make sure the thermocouple wire attached to the back of the board is away from the other wires.

7Install the screws holding the bottom to the kiln.

Replacing the Temperature Controller

1Unplug kiln.

2Remove the 4 corner screws holding the control- ler faceplate to the switch box. Carefully lift out face- plate.

3Disconnect the wires from the back of the board. You will find two plugs and two sin- gle wires.

4Connect the wires to the new board. Rein- stall faceplate.

Replacing the Firing Chamber

When the element burns out, the ceramic fiber firing chamber must be replaced.

To test for a burned out element, you will need an ohm- meter:

1Unplug the kiln.

2Remove the back of the kiln (page 18, left column).

3Place ohmmeter leads against the element connec- tors. A no-needle-movement reading on an analog meter, or OPEN on a digital meter, indicates a burned out element.

Replacing the firing chamber is a factory repair.
