  If the blower in your Matsui Dryer doesn't turn on, there are several things you can check. First, ensure the disconnect or breaker is turned on. Then, inspect the fuse and replace it if necessary, and verify all power connections are secure. Also, make sure that no value is entered in the 'TIMER' mode. Check the contactor coil for 100V; if present, replace the magnetic contactor. If there's no voltage, it's best to contact Matsui Service. Try resetting the overload. Follow the Maintenance Instructions to check the contactor; if it's fine, replace the overload relay. Finally, check for any loose or shorted wires.
