The symptoms of a damaged electric coupler are failure to heat, leakage, tripping or automatic shutdown, and noise.

1, unable to heat: the electric kettle has been plugged in and does not heat.

2. Leakage phenomenon: touching the metal part of the electric kettle, it is very dangerous to feel the current passing through.

3. Tripping or automatic shutdown: The tripping or automatic shutdown of the electric kettle is due to the unstable power supply caused by the failure of the coupler, which triggered the automatic protection mechanism of the electrical appliance.

4. Noise: If the coupler of the electric kettle is broken, it will produce noise, such as clicking, scraping or meshing.
