I received an error message stating the firing aborted because the kiln was failing to heat. Is it a faulty relay?

While “Failing to Heat” errors can be caused by a failed relay, there are additional possible causes...

A “Failing to Heat” error can be caused by a failed relay, but it can also be caused by:

  • Failed thermocouples
  • Faulty wiring
  • Inadequate supply power

The best course of action is to contact your kiln manufacturer for further assistance in troubleshooting the cause of the alarm.
