ABSTRACT:
An apparatus for intermittently sounding an audible alarm when the temperature within a deep freezer rises to a predetermined level which is less than the freezing temperature of most food products so that steps can be taken to prevent the food products from thawing. The apparatus includes a remote bulb element which intermittently opens and closes a container of liquefied gas which is permitted to expand and sound an alarm when the freezer malfunctions.
