Frigidaire Range Error Code F028

F028 on a Frigidaire range means the oven's user interface microcontroller cannot establish communication with the touch microcontroller during startup. Both of these processors need to successfully handshake when power is applied for the control panel to function. The error prevents the oven from accepting any user input until the communication issue is resolved.

When F028 is active, the control panel cannot reliably receive or process commands, which means the range should not be used until the error is resolved. Attempting to operate the oven in this state could result in unpredictable behavior. Disconnect power and perform the reset procedure before attempting any further use.

If the fix requires replacing the user interface control board, parts alone typically range from around $100 to $300 or more depending on the specific model. Adding professional labor, total repair costs generally fall between $150 and $450. If the error is caused by a loose connection or resolves with a power reset, there may be no parts cost at all.

A power reset is the first recommended step and will clear the error if the fault was caused by a temporary disruption such as a power fluctuation or a corrupted processor state. Disconnect the range from power, wait at least 30 seconds, then reapply power. If the F028 code returns after the reset, the user interface control board likely has a hardware fault and will need further diagnosis or replacement.

Start by disconnecting power to the range for 30 seconds to allow both microcontrollers to fully reset and reattempt communication. If the error clears, monitor the range for recurrence. If the error returns, inspect all wiring connections and ribbon cables at the user interface assembly for looseness or damage. A persistent F028 error that survives a power reset typically requires replacement of the user interface control board.
