Kenmore upright freezers that feature an electronic temperature control use a 9-volt battery backup for power outage situations. When the battery is low and requires replacement, a "b"– sometimes mistaken for the number "6" -- appears on the temperature control display, and the unit beeps repeatedly every 5 seconds.
The location of this battery depends entirely on your freezer's model/series. Once you find the battery compartment, replacing the battery is as simple as disconnecting the old battery and then connecting the new one.
Touch the "Alarm/Reset" key on the temperature control panel of your Kenmore upright freezer to turn off the beeping.
Locate your specific Kenmore upright freezer's back-up battery compartment. Look for a plastic battery compartment cover on the right front side of the front grille or on the freezer's service panel.
Remove the battery compartment cover. If you have difficulties removing it, place the tip of a small, flat-head screwdriver, knife or pushpin into the seam between the cover and the compartment and carefully pop the cover off the front of the compartment.
Slowly pull the freezer's 9-volt battery out of the compartment. Disconnect it from the terminal connectors. Set the battery aside for disposal.
Attach a new 9-volt battery to the connectors. Push the new battery and connectors/wires into the compartment.
Push the cover back into its original position. If necessary, touch the "Alarm/Reset" key if the unit starts beeping again.
