Verify Before Replacing Parts

  2. Verify current draw, overload status, and control signal before condemning the compressor or drive, given that the most likely cause listed above.
  3. Look for upstream conditions such as airflow or charge issues that may be pushing the compressor into protection, and check the next candidate on the list.
