What should I do if the bathroom light goes out?

This is the case if it is a switch with a leak protection:

1. Check whether the empty opening capacity is large enough, that is, whether it is overloaded, method: the total power of this circuit (W) 220 to obtain the current of this circuit, to see whether it is lower than the rated current of the empty opening.

2.If there is a leakage phenomenon, (1) check the load, check the insulation of each load to the ground with a shake meter, 2 disconnect all loads, and check the insulation of the empty lower line to the ground.

Let's get an electrician.

It should be a short circuit, it is recommended to find an electrician to repair it, do not repair it yourself, improper operation is dangerous.

If the voltage is too high, ask the electrician to check the circuit to see if the neutral line is broken.

1. In case of power failure, remove the bathroom lamp, observe whether the lamp has blackened traces, and replace the lamp directly (electronic rectifier element breakdown, or lamp head insulation aging breakdown);

2. Observe whether the wires or lamp heads have blackened marks, and replace the wires or insulated if there are any;

3. Check whether the socket is a fire and a zero after power transmission, if so, test whether the bathroom light is normal (after the above steps, if the light is not on, the bathroom lighting circuit should be checked).
