Possible Causes
How to Fix / Troubleshooting
Safety: Unplug the unit and allow heaters to cool completely before inspection.
Steps:
- 1. Visual inspection: Look at the grill element and convection heater cover for breaks or burn marks.
- 2. Test modes: Try both grill and convection separately to see which function fails.
Advanced: A technician can test heater elements and thermostats for continuity and replace any open components with Sharp-approved parts. If heaters are good, the control board relay may be faulty.
