Frequently Asked Questions

What does Frigidaire oven error code F93 mean?
Error code F93 indicates that both door lock switches are signaling a locked position when the oven starts up, preventing normal operation. This is typically caused by faulty door lock switches or a malfunctioning lock motor assembly.
Can I still use my Frigidaire oven with error F93?
No, you cannot use the oven with error F93 displayed. This error prevents the oven from starting any cooking cycles as a safety feature to prevent operation with a potentially faulty door lock system.
How much does it cost to fix Frigidaire oven error F93?
DIY repair costs range from $50-150 for replacement door lock switches or motor assembly. Professional repair typically costs $200-350 including parts and labor, depending on which components need replacement.
Why do both door lock switches fail at the same time?
Both switches rarely fail simultaneously. The F93 error usually indicates one faulty switch sending a false 'locked' signal, while the other switch may be working correctly. The control board interprets conflicting signals as both switches indicating locked status.
How long do Frigidaire oven door lock assemblies typically last?
Door lock assemblies typically last 8-12 years with normal use. Heavy self-cleaning cycle usage or frequent door operations can reduce lifespan. High humidity or kitchen grease exposure may also accelerate component wear.
