What is the reason why the lamp doesn't work? How to fix it?

First of all, the tungsten wire of the lamp tube is burnt out.

When the light is off, the first thing to check is the tungsten wire in the light, because this is the most common reason why the light is off. Therefore, if the lamp tube is not bright because the tungsten wire of the lamp tube is burnt out, just replace it with a new tungsten wire.

Second, the circuit breaker open circuit

Then check whether there is any problem with the circuit breaker, because once the circuit breaker is burned out, it will lead to circuit problems. So use an electric pen to check whether it can be electrified normally. If there is a problem, it needs to be replaced immediately.

Third, the switch fuse is blown.

If there is nothing wrong with the circuit breaker, then you can check whether the fuse of the switch is blown. If the fuse of the switch is blown, it needs to be replaced with a new fuse.

Fourth, the line problem.

If the fuse of the switch is also intact, you need to check the wiring at home. See if there is an open circuit, which makes the light not on. Because rats may bite the wires, they need to find an open place and stick it with tape.
