Possible Causes

Tripped circuit breaker, Loose power connection at terminal block, Blown internal fuse, Failed EOC

How to Fix / Troubleshooting

Safety first: Turn off power at the breaker before opening any access panels.

Steps to try:

  • Check breaker: Verify the oven's breaker is not tripped. Reset if necessary.
  • Inspect terminal block: With power off, check the terminal block for loose or burnt connections. Tighten or replace as needed.
  • Internal fuse: Some BlueStar ovens have an internal line fuse on the control board. Test and replace if blown, but investigate the cause of the failure.
  • Replace EOC: If power is present at the board but the display is dead, the EOC is likely failed and must be replaced.
