Caloric Range Error Code F5

The F5 code on a Caloric range indicates a defective watchdog circuit inside the ERC3 electronic range control. The watchdog circuit monitors the control's processor and flags a fault when the processor fails to respond correctly. This is an internal board-level failure, and the ERC3 control must be replaced to resolve it.

It is not recommended to continue using the range while the F5 code is active. A failed watchdog circuit means the control board's internal safety monitoring is compromised, which could result in unpredictable oven behavior. Discontinue use until the ERC3 control has been replaced.

Repair costs depend on the price of the ERC3 replacement control board and whether you hire a technician. Parts alone typically range from around $100 to $250 or more depending on availability. Adding professional labor for diagnosis and installation can bring the total repair cost to somewhere between $150 and $400 or higher.

The repair for F5 is replacement of the ERC3 control board. A knowledgeable DIYer comfortable working with appliance electronics can perform this replacement, but it requires disconnecting power to the range before starting and carefully handling the control board. If you are not comfortable working with electrical components, a qualified technician should perform the repair.

Resetting the range by cutting power at the breaker may temporarily clear the F5 display, but the code will return because the fault is a hardware failure inside the ERC3 control board. A reset does not repair the defective watchdog circuit, so the error will reappear during normal operation.
