Refrigerator Compressor Running but Not Cooling
This will not tell you if the capacitance is correct, only that the capacitor will store charge. When you replace a capacitor, get the exact type of the existing capacitor and the same capacitance value. You can safely use a capacitor with the same or higher voltage rating than the original. If everything checks out, go to the next item.
How to Fix a TV that Won''t Turn ON but Red Light is

6 FAQs about [Capacitor light is on but not switching]
Why did I install a light switch without a capacitor?
I installed it without the capacitor because I use ordinary (incandescent) bulbs and there can not be any flickering. I think the provided capacitor is only for LED lights to prevent them from flickering. That switch burned out yesterday when my mother pressed the touch sensor to turn the lights on.
Can you use a capacitor on a light switch?
If you install a capacitor across a light switch, there will be voltage present on the line, and some current through the attached incandescent, starter-based flourescent, and maybe LED lamps, as well as motors. Why can’t we use a capacitor at home for lighting or heating?
Can you put a capacitor on a LED light bulb?
Unless you need some current to pass constantly to power this special kind of switch you shouldn’t install such a capacitor with the bulb. When the switch is off, we can't allow any current through, or LED light bulbs will flicker. Therefore, we need a low standby current. WiFi is therefore out of the question. This leaves:
What happens if you put a capacitor in front of a light?
If the capacitor is in parallel with the light bulb, it will have no effect, and the bulb will light normally if it is rated for the supply voltage. If the capacitor is in series with the bulb, the bulb will light if the capacitance is large enough so the reactance is small compared to the bulb resistance.
What happens to the capacitor when the switch closes?
The capacitor is initially unchanged. Immediately after the switch closes, the capacitor voltage is © 2013 Pearson Education, Inc. Figure (a) shows a circuit that charges a capacitor.
Why is my capacitor not working?
It's possible that the capacitor has failed after the repair was completed, or a solder joint has come loose. If this is the case, take it back to the shop that did the original repair. They should work with you, though don't expect them to cover the entire cost of another repair.
