Error codeF40 / F41
ApplianceRange
Two displays, one fault
Current Frigidaire ranges and wall ovens with an electronic oven control (EOC) can show either F40 or F41. Both stand for a cooktop lockout error, and the range guide lists them together as Cooktop Lock Out.

All of it needs a technician, so read the list as a preview of the visit.
When the code will not go away
An oven installed within 30 days goes back to the installer, says the guide. Later than that, Frigidaire is the one to contact for scheduling service.
For a cooktop lockout in a San Francisco kitchen, phone (415) 319-6371 and give the code on the screen, the model number and any reset you made. Frigidaire range repair has the overview.
Model compatibility: Frigidaire reuses codes across series and model years, so F40 / F41 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
F40 and F41 both report a cooktop lockout error.
Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
