Dometic duo therm. Wierd issue need some input

[The Mylles Family]

Okay my rooftop a/c blows cold as can be, the issue comes when it reaches the desired temp, the blower shuts off, but it continues "Humming" as if the compressor is still running. It's not actually running, but it Buzzes or hums like it is.  I had issues with it not comming on last year & replaced the analog thermostat which solved the issue... But this is super annoying..
Please help

Could be several things humming.

Take some time and get up on the roof. Remove the cover and cycle the unit to see if you can identify where the noise is coming from.

If it comes back on in a few seconds, that is normal and it is just changing the fan speed
