Is it safe to keep using?
No. A shorted or stuck element can cause localized overheating, arcing, or fire. Do not operate the oven until the element and relay are inspected.
Can I reset the code?
Yes. A breaker reset may temporarily clear F9, but if the element is visibly damaged, replacement is required regardless.
When to stop immediately?
Stop if you notice: F9 appears on every self-clean attempt without variation, The oven door has visible warping or damage at the top edge.
Symptoms You May Notice
Oven heats unevenly with hot spots
One area of the oven cavity runs much hotter than others, causing uneven browning and charring on one side of baked items.
Broil element does not turn off
The upper broil element stays glowing red even when set to bake mode, creating excessive top heat and potential burning.
F9 appears during broil or self-clean
The fault code triggers during high-heat modes when the oven detects the element has exceeded safe operating parameters.
Visible damage to heating element
The bake or broil element shows bright spots, sagging, or blistering that indicates internal failure of the heating wire.
Possible Causes
Shorted bake or broil element
The heating element has developed an internal short causing localized overheating. A damaged element can arc against the oven cavity wall.
DIY PossibleStuck relay on the EOC board
The relay controlling the element output has fused closed, keeping the element energized even when the board attempts to turn it off.
Requires ProfessionalSafe Checks You Can Do
-
1
Visual element inspection
With the oven off and cool, visually inspect both the bake (bottom) and broil (top) elements for bright spots, blistering, sagging, or holes.
Any visible physical damage to an element means it must be replaced before next use.
-
2
Test element resistance
With the breaker off, disconnect the element leads and measure resistance. A good element reads 20-50 ohms. Open circuit or very low resistance indicates failure.
An element reading below 10 ohms has an internal short and must be replaced immediately.
