    .Maybe the teeth on the ring gear or or starter are worn.Pull the starter out and check them over.Rotate the engine by hand when you check the ring gear to make sure you see all the teeth on it

    Good day reeferwrencher hope you are fine slctrucker suggested that it may be the shut off solenoid located close to the belts attached to freon line thanks

    Does the engine start? Does the sound disappear after the starter de-energizes. If so I would check the starter and ring gear as i suggested earlier.The fuel solenoid makes a click as it pulls in just before the engine cranks,thats normal.I would assume that isn't the noise you're referring to as you said this noise just started happening recently. Is that correct?

    It started recently the noise like air pressure/freon comes from the right side when facing the motor between the long belt and eye glass there is 12 v solenoid that goes thru freon line just my suggestion

    That's the pilot solenoid that controls the three way valve. Put the unit on an automated pre trip if it passes then dont worry about it

    Might be 3 way valve shifting maybe make a video with sound and post it up here if possible but I dont think it's anything to worry about

    If the ball is floating in the receiver tank sightglass then your freon level is fine.If you're worried about it then set it for -10 f while empty and let it run overnight on a test run.
