What LOC means on a Frigidaire freezer
The LOC code on a Frigidaire freezer indicates that the display lockout feature is currently active. This is a software-level control state, not a hardware fault or component failure. When LOC is displayed, the control panel is intentionally locked, meaning all user inputs for temperature adjustments and extreme freeze function changes are disabled. The freezer continues to operate normally at its last set parameters; the lock simply prevents accidental or unauthorized changes to the settings.
The display lockout is managed by the main control board's firmware and is activated through a deliberate button sequence. It is commonly triggered by an accidental press-and-hold of the ALARM RESET key, or in households with children where the lock is intentionally engaged to prevent setting changes. The LOC indicator will remain on the display indefinitely until the unlock procedure is performed. Because the freezer keeps running at the previously configured temperature, no food safety risk is introduced by this state.
To clear the LOC code, press and hold the ALARM RESET key until the control emits a beep and the display changes from LOC to UL, which confirms the panel is now unlocked. Once UL appears, normal control panel operation is restored and temperature or extreme freeze adjustments can be made again. If the LOC code returns immediately after unlocking, the ALARM RESET key itself may be stuck or experiencing intermittent contact issues, which would require inspection of the keypad.

Common causes of LOC
- 01
Accidental activation of the lock feature
Wiring / connectionThe display lockout is easy to trigger unintentionally by leaning against the panel or pressing the ALARM RESET key for an extended period. This is the most common reason LOC appears with no prior user intent to lock the controls.
- 02
Intentional lock engaged by another user
Wiring / connectionAnother household member, such as a parent child-proofing the appliance, may have deliberately activated the lock. Check with others in the home before proceeding to diagnostic steps.
- 03
Stuck or intermittently shorted ALARM RESET key
Wiring / connectionA keypad button that is physically stuck in a depressed position or has debris beneath it can continuously trigger the lock sequence. Inspect the key for visible sticking or residue and clean around the button.
- 04
Faulty keypad membrane
Part replacementIf the LOC code returns immediately after unlocking, the keypad membrane may have a damaged contact beneath the ALARM RESET key that is sending a continuous or repeated signal to the control board. Replacement of the keypad assembly would be needed.
- 05
Control board retaining lock state after power interruption
Wiring / connectionIn rare cases, the main control board may retain or incorrectly restore a locked state after a power outage or surge. Performing the unlock procedure after power is restored typically resolves this.
