Hi, I'm Tim and I'm an HVAC expert here to assist you with your questions. Please provide all information I request as it makes it more difficult to troubleshoot something when I'm not there onsite. Essentially, you become my eyes and ears. Thanks for the opportunity to help.

Please be patient as many times we work with several customers at once.
Is it whole outside unit that turns on for 10 sec, then off, or just compressor?
Sounds like a stuck compressor. Have you checked run cap for compressor for signs of bulging or being deformed?
run capacitor. Inside the unit in the area where all the electrical components are. Looks similar to this.
Typically on a bad one the top will be deformed or "bulging"
Either way, it sounds like a stuck compressor. Whether compressor itself is bad or just run capacitor. Both can cause the compressor to not start or attempt to start, but not actually run. Let me know if you have additional questions. Otherwise, good luck! Thanks for using Just Answer and please don't forget to rate my service as that's how experts get paid (thanks in advance for any bonus left). Otherwise experts work at their own time and expense. Feel free to post back with any more questions. Remember, you can rate question at any point and still ask more questions (related to the same thing) later on. Experts prefer if you rate question at the end of our first chat.
