Troubleshoot an INF infinite input switch

  1. On an L&L manual kiln with INF switches the indicator pilot light is always wired to the load-side of the switch.
  2. If the light is cycling on and off, and then stays on all the time only when the switch is on HIGH, you know the switch is fine.
  3. If the light does not come on; first check and see if the other INF switches' indicator lights are able to come on.
  4. If they do and it is just the one light on one INF swtich not coming on- then it is most likely a bad switch.
  5. If all the lights are out then probably the problem has something to do with the kiln-sitter or maybe the power supply.
  6. See all parts that relate to this.
