Don't just make sure it's off- if at all possible UNPLUG IT!!! You can't imagine how many time's I've been shocked by things that are "off," and it always surprises you, too. Better safe than sorry!CHScrew said:If it's not the nuts/bolts making the noise, but it's comming from the fan. take the cover off of the fan (make sure unit is in the off position) and oil the fan. Also, make sure that there isn'r anything that is hitting the fan blades.
Out spot is like 9 yrs. old and ust to make noise. We did what I said above and for the most part, it stoped.
Ditto. I haven't been shocked as yet but you would always unplug an item rather than just relying on a switch. If it is hardwired, find its breaker and turn it off there. There is a principle in electrical work that goes along the lines of assume that something is live until you have proven that it is dead. In this instance something like metering it and obtaining 0V or very close to it would be considered to be proving it dead. We don't want to all be sending condolences because someone decided that all they needed to do was turn the switch to "off" and that they would be right. Take for instance your television, whilever you can turn it on with a remote control, it has power running through it. It can bite in this "off" state.Radman said:Don't just make sure it's off- if at all possible UNPLUG IT!!!

It could just be me but I am thinking that the power supply should not be vibrating noticeably. If the power supply is "huge", then it probably has a rather large ballast in it. It may be that the ballast or some other part of the power supply is not in its best state. It may be that it needs a good clean, but as I said in my earlier post, exercise EXTREME CAUTION should you decide to open it up. It is my advice that you refer this to qualified service personnel. it likely does have a high voltage supply, especially if your spot has a discharge lamp. I realise that you have given a model etc. I have not looked it up. What I am doing is making general comments, so that if others read this thread, they can hopefully apply some of what is being said to their own models.mbandgeek said:
