My fridge is an 'Estate' by Whirlpool.
The timer is a 10 hour timer on mine, the timer runs whether the compressor is running or not.

The defrost cycle only runs if the refrigerator thermostat is asking for the compressor to run. ..so if the compressor is running and cooling, it will cut off the compressor and start the defrost.
If the compressor is not running, it has a 23 minute 'defrost window' for the defrost cycle to run so if the compressor just shut off and the defrost timer window starts, it might not run defrost if the thermostat doesn't turn it on too.

I imagine it's usually halfway through the defrost window before it normally starts the cycle though. If there isn't a bunch of frost built up, it will run the cycle for 7 minutes until the defrost thermostat shuts it off, then it will wait until the total of the 23 minutes has done by and turn the compressor back on.

Yours is probably very similar.
