Frigidaire Range Error Code Er

The Er code on a Frigidaire range is a safety indicator that appears at power-up or after a power failure when one or more of the four surface burner control knobs were left in the ON position. The control board detects this condition during its startup sequence and locks the surface controls to prevent unintended burner activation. Turning all four knobs to the OFF position and resetting the clock will clear the error in most cases.

When the Er code is active, the range holds the surface burner controls in a locked state, so the burners will not operate. This is a deliberate safety feature, not a malfunction. The oven functions may still be available depending on the model, but you should resolve the Er condition by setting all knobs to OFF before attempting normal use of the surface burners.

In most cases, the Er code requires no parts and no repair cost at all since it is resolved by simply turning the burner knobs to the OFF position. If the error persists due to a defective knob switch, replacement parts and labor could range from roughly $50 to $150 depending on the specific component and your location. A control board replacement, if required, typically falls in the range of $150 to $400 or more including parts and labor.

To fix the Er code, turn all four surface control knobs firmly to the OFF position, making sure each one clicks into the OFF detent. Once all knobs are confirmed off, the Er code should clear. You will then need to reset the clock on the range since a power interruption typically resets the display. If the error persists after completing these steps, a knob switch or control board issue may need to be diagnosed.

The Er code is cleared by turning all four surface control knobs to the OFF position, not by a power cycle reset alone. In fact, the code appears because power was already cycled with knobs left on. After setting all knobs to OFF, reset the clock to complete the recovery process. A power cycle without first setting the knobs to OFF will likely cause the Er code to reappear immediately.
