Hi Betsy,


Thanks for using FixYa. Clicking sound usually means a bad start relay and over load for the compressor, as you said that the inside top of the unit runs and the fan beside the compressor runs then to check the compressor properly you should test it with an amp meter, each compressor is rated in running amps (see model/serial tag or the sticker on the compressor)...if the compressor is drawing too much current, this may be why it is shutting off. Check the model tag for proper amp rating. Some relays will be easy to notice the broken with them, they may be burnt. Some of these relays can be removed and give them a little shake, and if they rattle around inside the relay is likely bad. Compressors can also seize and click on and off or one of the electrical windings inside the compressor could have opened up. You can use a test cord to help check the compressor and this also will help with the amp test. If the compressor checks ok and you want to install a replacement start relay then you’ll need to find out which winding is which. You will need an ohm meter to determine the windings. As the HVAC Tech. has already checked it so I would say it is the compressor that has gone bad and should be replaced.


Please do accept the solution if the issue is resolved or else revert for further assistance.


Thanks
