A wire getting loose in a terminal screw or in a wire connector at the switch or light fixture could cause the flicker.
Why does my wall switch keep spt a red light.
When the light comes on.
If you have a screwdriver voltage tester insulated pliers and a wire connector you can troubleshoot your light switch to determine the problem and if necessary replace the switch.
If it s a regular switch timer with a knob and an on off lever clear the settings back to zero first.
The connected light should illuminate indicating that the start time has been set.
I have a light switch on my wall in my living room and bedroom.
Twist the knob to the desired start time and then press it in.
Unfortunately there is no obvious light fixture either place and the switches do not control any outlets.
What is the best way to check if there is a box in the ceiling short of putting a hole in the ceiling.
Turn your light switch to the on position then flip it off for two to three seconds.
A corroded contactor inside the switch could cause the flicker but would also probably cause the switch to feel warm at the touch.
Turn the switch on and check your lights.
It is also possible that the light fixture or switch has loose connections or a short circuit that causes intermittent failure so if the problem persists after you ve replaced the switch have a look at the light fixture next.
A light switch is inexpensive and has small parts entirely contained inside a plastic casing so if the switch is bad the best option is to replace it.
Flip the switch to on and wait for the red indicator light to illuminate.
I know i could call an electrician and may if i find out there is a box.
