ABSTRACT:
A control device for a freezer in which a compressor whose operation has been stopped due to low lubricating oil pressure may be automatically restarted. This control device eliminates manual restarting of the compressor repeatedly until it becomes fully operational and facilitates discovery of the true malfunctioning of lubrication mechanisms for bearings in freezer compressors, by prohibiting automatic restarting once the compressor has been operating at normal oil pressure for a preset amount of time.
