Understanding Oven Error Codes

How Error Codes Work

Modern Oven Diagnostics:

• Control board monitors all oven functions
• Sensors detect temperature, door status, and component operation
• When something's wrong, board displays error code
• Code pinpoints specific problem area
• Helps technicians diagnose faster

Types of Error Codes:

• Temperature errors (F1, F3, F10): sensor or heating issues
• Door errors (F9, door, LOC): door lock problems
• Communication errors (SE, Er dH): control board issues
• Component failures (F7, F8): specific part malfunctions

When Error Codes Appear

Common Triggers:

• During self-clean cycle (most common)
• After power outage or surge
• When oven overheats
• After years of use (component wear)
• During preheating
• Immediately when turned on
