Possible Causes

Element shorted to earth, Pinched wiring harness, Moisture inside element sheath, Shorted suppression capacitor or filter

How to Fix / Troubleshooting

Safety first: Do not repeatedly reset a tripping breaker. Isolate the oven and verify no power is present.

Steps to check:

  • Identify function: Note which function causes the trip (fan oven, grill, base heat). This points to the suspect element.
  • Disconnect suspect element: Remove the rear cover and disconnect the element for the problematic function. Restore power and test another function. If the trip stops, the element is faulty.
  • Replace element: Install a new Tower-compatible element for the affected function.

Note: If trips occur on all functions even with elements disconnected, the issue may be with the wiring harness or filter board and should be checked by a technician.
