sears (gibson) chest freezer won't cool

This freezer is kept in the garage and was not plugged in until recently. I can hear a gurgling sound, and it won’t cool. Please help!!

If you are hearing a gurgling sound I think you are low on refrigerant. Time to call a service tech

I have a Kenmore 106.545.84400. My ice maker stopped working too. The water dispenser is still working. I tried sticking a chopstick up the chute that fills the tray and there doesn’t seem to be an obstruction. What am I missing?
