Frigidaire Range Error Code F019

F019 indicates that the oven's user interface board is unable to configure the relay board during their startup communication sequence. The relay board controls power to the oven's heating elements, so the oven will not operate while this fault is active. The error points to a breakdown in the control signal path between these two boards, which can be caused by wiring issues or a failure in either board.

The oven function should be considered inoperable while F019 is active, as the control system has detected a communication fault and will prevent normal operation. Surface burners on gas models may still function depending on the specific range configuration, but you should not attempt to bypass or ignore the error code. Address the underlying fault before resuming normal use of the oven.

Repair costs vary depending on the root cause. If the fix is simply reseating a loose wiring harness, costs may be limited to a service call fee, typically in the range of $75 to $150. Replacing the oven relay board generally runs $150 to $350 including parts and labor. Replacing the user interface board can cost $200 to $450 depending on the model and labor rates in your area.

A power reset is always the recommended first step. Disconnect power to the range at the breaker or by unplugging it, wait at least 30 seconds, then restore power. If the error was caused by a temporary glitch or power fluctuation, the reset will allow the boards to reattempt configuration and may clear the code permanently. If F019 returns after the reset, a hardware fault is likely present and further diagnosis is needed.

Start by performing a power reset: disconnect the range from power for 30 seconds, then restore it. If the error returns, inspect the wiring harness connecting the user interface board and the relay board for loose connections, corrosion, or visible damage. If the wiring looks intact, one or both control boards may need to be tested and potentially replaced. A qualified appliance technician can perform resistance and continuity checks to isolate which component has failed.
