Possible Causes

Blown internal fuse on control board, Loose neutral or line connection to control, Failed transformer (if used), Faulty control board

How to Fix / Troubleshooting

Safety first: Turn off power at the breaker before removing any panels. Do not bypass fuses with foil or wire.

Steps to check and correct:

  • Verify breaker: Confirm the range breaker is on and not tripped.
  • Inspect terminal block: Remove the rear cover and check for loose or burnt connections at the power terminal block.
  • Access control: Remove the control panel to access the control board. Look for an onboard fuse and test it with a multimeter. Replace only with the exact type and rating.
  • Check wiring to control: Ensure the control is receiving line and neutral voltage (this test should be done by a qualified person).

When to call a technician: If the fuse blows again or the control board is not receiving proper voltage, professional diagnosis is needed.
