  If your Oster Coffee Grinder isn't grinding, several factors could be at play. First, make sure the timer is correctly set. Then, check that the hopper lid is securely closed and the ground coffee chamber is properly positioned. Ensure the start button has been pressed and the unit is plugged into a working outlet. If there's a power outage, wait for the power to be restored. If the motor has overheated and the thermal fuse is broken, it is recommended to call an authorized SUN-BEAM® service center.

  Your Oster Coffee Grinder might stop grinding because the timer setting is incorrect, or the timer was inadvertently rotated to the OFF position, so please set timer correctly. Also, ensure the hopper lid is closed and the ground coffee chamber is correctly positioned. If the cancel button was pressed, press the start button again. Check that the unit is plugged in and there isn't a power outage. Finally, if the ground coffee chamber is full and clogging the burr mill compartment, remove, empty, and replace the chamber. If needed, unplug the unit and clean the burr mill compartment.

  If your Oster Coffee Grinder produces insufficient coffee grounds, it could be due to several reasons. First, ensure the timer setting is correct and add beans to the hopper. Also, check that the hopper lid is closed and hasn't been opened during operation. Make sure the ground coffee chamber hasn't been moved out of position during operation. If the top burr mill isn't in the proper position, unplug the unit and place it correctly. Lastly, if the unit and burr mill aren't clean, unplug the unit and clean the burr mill.

Also, check for any foreign objects between the two burr mills; if there are any, unplug the unit and carefully dislodge them.
