A:Answer John, A 115 Volt, 60 Hz., AC-only, 15- or 20-amp fused, grounded electrical supply is required. It is recommended that a separate circuit serving only your freezer be provided. Use an outlet that cannot be turned off by a switch. Do not use an extension cord. NOTE: Before performing any type of installation, cleaning, or removing a light bulb, press and hold TEMP SETTING for 3 seconds to turn off cooling, and then disconnect the freezer from the electrical source. Hopefully this information is beneficial to you. Thank you for your inquiry regarding our Whirlpool appliances!
