Display shows E3; oven may not heat or may shut down shortly after starting.

Safety First: Turn off power and allow the oven to cool completely. High-limit devices are safety-critical.

• Check ventilation: Ensure that the oven vents are not blocked and that the unit is installed with proper clearances.
• Locate thermal devices: Remove the rear panel or top cover to find thermal fuses or high-limit thermostats mounted on the oven cavity or rear panel.
• Test continuity: With power off, disconnect one wire from each thermal device and test for continuity. Replace any open thermal fuse or thermostat with the exact Danby-specified part.
• Investigate cause: If a thermal fuse is blown, inspect for failed cooling fan, blocked vents, or runaway heating element that may have caused overheating before restoring operation.
