The following are common reasons and solutions for the shredder not powering on, sorted by priority:
1. Power problem
Loose or damaged power cord: Check whether the power plug is plugged in tightly, or try to replace the power cord.
Power failure: If the power module is burned out (such as transformer damage, temperature fuse blown), use a multimeter to detect the voltage, replace the damaged parts or send it for repair.
2. Internal failure
Circuit board or fuse damage: Check whether the fuse is burned out (such as 3.15A/250V specifications need to be replaced) or the circuit board is short-circuited (such as voltage regulator breakdown need to be replaced).
Motor or transmission component failure: If the motor is damaged, the transmission belt is loose, etc., it is necessary to disassemble the machine for inspection or contact professional repair.
3. Overheat protection triggered
When the motor overheats due to continuous use, some models will automatically cut off the power for protection, and need to wait for more than 30 minutes to cool down before restarting.
4. Other possible reasons
The scrap bin is not closed: Some models are designed to not be powered when the bin is not closed.
Switch failure: Check whether the switch has poor contact or is damaged.
Recommended operation sequence: First check the power cord and switch → test the fuse and circuit → check for overheating protection → send for repair of complex internal faults. If the problem persists, it is recommended to contact a professional repair point for processing.
