How to Fix / Troubleshooting

Safety first: Turn off power at the isolator before removing any panels.

  • Check cooker switch: Ensure the wall isolator is fully on and not partially engaged.
  • Inspect terminal block: Remove the rear cover and check for burnt or loose connections at the main terminal block.
  • Thermal cut-out reset: Some AGA models have a manual reset thermal cut-out accessible from the rear or top. Press the reset button if present (only once, and investigate cause of overheat).

When to call a technician: If the cut-out trips repeatedly or wiring is damaged, professional repair is required.
