My loft fluorescent light isn't working. I've tried replacing the starter and bulb, which didn't work? ?

Question

I've tried both of these things, and have verified that the new ones work by testing them in a similar light in the kitchen. I've noticed a grey cable running from the light to the switch, and have checked inside the switch, all of which seems to be fastened correctly. Any help would be greatly appreciated.

Answer 1

I agree that it sounds like the ballast or you are not getting electricity to the fixture.  Have you checked your circuit breaker box?  Before you attempt to replace the ballast you need know that you have NO electricity to the light fixture.  The safest way is to pull the fuse or flip the breaker at the box.  How comfortable are you working with a meter or around electricity?  It is not hard but you have to be careful not to hurt yourself or others. Have you ever worked with wire nut connectors?  The look like little road cones that twist on so that you can join 2 or more wires together.  Art H

Answer 2

You may need to replace the balast.

Answer 3

if you have replaced all those things and looked into the wiring, its probly a bad socket. they are cheap and easy to replace

Answer 4

Make sure there is power at the switch if ok is power going to the bulb if not, replace the ballast or the fixture.

Answer 5

Is it a fused switch, in which case check the fuse? Then check your fuse board- the light may have been put in on a dedicated fuse and the micro switch may have tripped. Follow the wire back and see if it is broken anywhere- it may have been chewed by rodents, though one would expect the RCD to trip in that case.

Finally, have you removed or switched off anything else that is normally on? I’m thinking that whoever installed the light in the loft ran it from another circuit (a 'spur’) and it may be reliant on another switch being on.

Finally, the fitting itself may be faulty.

Apart from that , don’t know! Good luck- and be careful. Electricity kills!

Answer 6

This once happened to me. The switch was set into the loft floor and some of the loft insulation had got into the switch. A  quick go with a brush and a blow for good measure and Hey Presto, it worked again. I hope that your problem is solved as easily.

Answer 7

yes, prolly the ballast................but may be cheaper to replace unit.

Habitat for humanity stores will have parts for great prices so check there first.
