1. Power cord failure: The power cord of the catering range hood may be damaged or aged in long-term use, resulting in abnormal power transmission and the range hood cannot be electrified.
2. Loose power plug: During use, the power plug and interface of the range hood are loose or damaged, which will affect the electrified load and cause the range hood to fail to work normally.
3. Motor failure: The motor is the core component of the range hood. If the motor is damaged or aged and can't work normally, it will also lead to the failure of the range hood to be electrified.
4. Capacitance problem: Capacitance is the key part of range hood start-up. In the process of charging and discharging, a large electric field intensity is provided. If the capacitor is damaged, the current can't be conducted, and the range hood can't be electrified normally.
5. Fuse damage: Fuse is a safety measure to protect electrical equipment from overload, short circuit and electrical damage. The failure of the fuse will cause the circuit to be interrupted and the range hood will not be energized.
To sum up, the above is the reason why the catering range hood is not electrified. In the process of use, do a good job of maintenance and cleaning in advance and use the range hood correctly, which can avoid the situation of power failure to the maximum extent. In case of the above situation, troubleshooting should be done in time.
