Abstract
A freezer alarm system and apparatus for monitoring the temperature in the freezer compartment of a refrigeration unit includes a housing mountable on a wall adjacent the refrigeration unit for plugging into a wall outlet. A capillary tube extends from the housing and terminates with a temperature sensor that is mounted inside the refrigeration unit for sensing when the temperature increases therein past a given temperature preset by an adjustable thermostat located on the housing. When this event occurs contacts within the housing close thereby actuating an audible buzzer and a visible luminary alarm warning the owner that the temperature within the refrigeration unit has exceeded a safe pre-set level and that the refrigeration unit needs checked for remedial action.
