1. An electronic controller which monitors a status of a compressor, comprising:

  • fault detecting means for detecting a fault in said compressor;

    timing means, connected to said fault detecting means, for initiating a predetermined timing period in response to a fault detected by said fault detecting means;

    power means for providing power to said compressor, said power means responsive to said timing means, for disconnecting power to said compressor when the detected fault is not corrected within said predetermined timing period, and for continuing power to said compressor when said detected fault is corrected within said predetermined period;

    means for resetting said timing means when said detected fault is corrected within said predetermined timing period; and

    an alarm circuit which activates an alarm in response to the detection of a fault by said fault detecting means and which deactivates said alarm at the conclusion of said predetermined timing period only if said fault is not corrected within said timing period, and which deactivates said alarm during said timing period only if said fault is corrected within said timing period.
