What the F02 error code actually means

Your Frigidaire washer is detecting a problem with the water temperature, meaning the part that measures water heat is either not working correctly or not getting a proper signal. This could be a faulty temperature sensor inside the machine or something as simple as the water hoses being hooked up to the wrong connections on the back of the washer. Until the issue is resolved, the washer may stop mid-cycle or refuse to run.

First diagnostic step
Check if incoming water hoses are connected properly. If so, disconnect both wires from the water temperature sensor and measure the resistance of the sensor. If less than 3K or more than 163K, replace the sensor.

Questions people ask about F02

What does F02 mean on a Frigidaire washer?
F02 on a Frigidaire washer indicates a water temperature problem. The control board is not receiving a valid signal from the water temperature sensor, either because the sensor has failed, the wiring is damaged, or the water supply hoses are not connected correctly. The sensor should measure between 3,000 and 163,000 ohms of resistance when functioning properly.
Is it safe to use my Frigidaire washer with an F02 error code?
Running the washer while the F02 code is active is not recommended. Without a functioning temperature sensor, the control board cannot properly regulate water temperature, which could result in incomplete cycles, poor wash results, or potential damage to fabrics. It is best to diagnose and resolve the fault before continuing normal use.
Will resetting my Frigidaire washer clear the F02 error code?
Unplugging the washer for a few minutes and restarting it may temporarily clear the F02 code, but the error will return if the underlying cause has not been repaired. A reset is useful for ruling out a one-time electronic glitch, but persistent F02 codes require hands-on diagnosis of the temperature sensor and its wiring.
How do I fix an F02 error on my Frigidaire washer?
Start by checking that both water supply hoses are connected to the correct inlet ports and that the valves are fully open. Next, disconnect the two wires from the water temperature sensor and use a multimeter to measure its resistance. If the reading is below 3K or above 163K ohms, the sensor needs to be replaced. If the sensor tests within range, inspect the wiring harness for loose or corroded connections.
How much does it cost to fix a Frigidaire F02 error?
If the fix is simply reseating a hose or reconnecting a loose sensor connector, there is no parts cost. Replacing a water temperature sensor typically costs between $15 and $50 for the part, plus labor if a technician is hired. If the control board is at fault, replacement parts can range from $100 to $300 or more depending on the specific model.
