Ice cream was soft, items were not freezing all the way. We found that the motor had stopped and the unit was hot. The air was still flowing but the fan was stopped. We bought the grommets because the old ones are really hard to separate from the motor and the fan was just gross. They were gummed up by the years of dust and moisture back there, way easier to replace those when you replace the motor. Used a compressed air can to clean out the other parts and everything is working well. It is dirty back there if you don't pull it apart and clean it regularly.
