My screen is blank and dark, but there is a flashing blue LED light inside. What should I do?

If you're seeing a flashing blue light, this is your controller's 'heartbeat.' This means your TAP Kiln Controller is operating in a normal state.

If there's no display, check all internal wiring and ensure the contrller display assembly is still connected to the controller IO board.

If the problem persists after verification of all internal wiring, please contact SDS Industries.
