Possible Causes
How to Fix / Troubleshooting
Safety Warning: Unplug the microwave before removing the control panel or accessing internal wiring.
Steps:
- Unplug the microwave for at least 10 minutes to fully reset the control electronics.
- Plug back in and attempt to set the clock and run a short cook cycle.
- If E15 reappears immediately, the control board is likely faulty.
Advanced (technician):
- Remove the control panel and inspect the main control PCB for burn marks, corrosion, or swollen components.
- Reseat all connectors to the board.
- If available, update or reflash firmware per Insignia service procedures (service-only function).
- Replace the main control board if the error persists.
Because this is a logic-level fault, there are no safe internal repairs for untrained users beyond power cycling.
