AbstractA temperature sensing means for a refrigeration apparatus including sensing means responsive to the temperature within a refrigerated space and to an ambient temperature condition for signalling the temperature condition of the refrigeration apparatus. In the disclosed embodiment, the sensing means is mounted in the access door of the refrigeration apparatus and the temperature sensors are mounted within a single housing. The sensor for sensing the ambient temperature is effectively insulated from the refrigerated space and senses the ambient temperature through a portion of the housing and door. In the illustrated embodiment, the sensing means is used to provide an ambient temperature compensated over-temperature alarm for the refrigeration apparatus.
