Occasionally some of the buttons on the keypad of the DynaTrol stop working.
This is caused by a loose or not fully connected plastic ribbon on the back of the keypad that connects the keypad membrane to the electronics.
- Turn all the Power OFF to the kiln.
- Open the control box so you can see the back of the DynaTrol.
- Locate the curling, striped, plastic ribbon at the bottom of the electronic circuit board.
- Pull the plastic ribbon out of the long black plastic slot, wipe it with something clean- like a tissue, then push it fully back into the long black plastic slot- the plastic ribbon will stay connected at the other end of itself underneath.
- Close the control box back up and try it.
- If it still does not work double-check it or replace the DynaTrol.
- Another trick to try: use a heat gun like an air dryer to heat up the front of the control board. Moisture buildup in the control can be one of the causes of the connections failing. Note: Just be careful not to set the heat gun to the highest setting, and let it sit too close to the surface for too long, or it can damage the controller. Heat guns can be pretty strong. A hairdryer on its highest setting might be a better bet.
