    Thanks will look for the cleaning solution at local home depot or lowes (just easier sometimes) but with the lights it is all the lights in the house that dim when it kicks on and it only for the first ....2-5 seconds or less I know that the a/c is on a 20 amp breaker so will check the loads on both sides & see how well they balance just hoping not the compressor ain't got that kinda cash right know...

The dimming of your lights at start up tell me two things, One is that the starting Amps may be a little high and drawing too much amperage. Have this checked by using an Amp meter. Secondly, look at your circuit breaker box. Does the Amp total on the right side of the box equal the left side. What I mean is that the Amp load of your box should be as close to equal as possible. If you have too many drawing Amps on one side, it puts strain on that side and will effect all breakers (loads) on that side. You can check this by investigating what circuits are on the same side of the box as your A/C unit and watch the lights associated to that same side and see if they dim when the unit starts. Also watch other lights associated to the opposite side and see if they dim. If they do, you have a compresser issue. To clean the coil you can purchase a coil cleaner at a local A/C repair shop and use a garden sprayer to apply. Rinse off the coil slowly and after you give it a chance to work. Too much water on the coil when rinsing will cause a flood in the bottom of the air handler and may not allow the drain to exacuate the water as quickly as designed. Rinse in moderation. Do this with all power off and the breaker locked in the off position.

SOURCE: filters for a C30A-054U-B condenser

Hi!
Try going to a local sheet metal fabricating shop or a heating/air conditioning shop. They can probably make some up for you. Usually a lot less expensive than trying to order some from Trane/American Standard.

Lights dim

if the grinder just hums then it is a 240 volt unit and will burn out on 110 volts
the garage power should be the same as the house 240 v
but if only 110 v that indicates that it is 1/3 of a 3 phase power supply
if it has just started then get a electrician in to check the reason for the power drop

Why do lights flicker

An electric water heater will draw a lot of electricity. Your house may not be wired well, and when the heater kicks on, your lights will dim some. If your house is over 25 years old, it's likely normal.

THE LIGHTS IN OUR UPSTAIRS BATH HAVE STARTED TO SLOWLY FLICKER DIM AND BRIGHT, DIM AND BRIGHT.

Replace your breaker in the breaker box, and I wouldn't use these lights till its fixed. Kill the lights, kick the breaker to the off position This is the first thing that happens before an electrical house fire.

We just moved into a new house, and whenever I use

It sounds like it could be one of the following issues:

1. Bad wiring to the bathroom receptacle - this should be a GFCI outlet.

2. There is an overload somewhere on the same circuit - try the dryer with nothing else turned on.

3. The hair dryer may be bad or have a bad cord, plug, etc. Hair dryers can also become plugged (the air inlet screen) and overheat.

4. There could be loose or other bad wiring somewhere in the circuit.

If you are not familiar with working with electricity, it would be best to call a qualified electrician. They are the pros and can correct the problem.

I have a Hunter fan with remote. The fan or the light comes on by itself with no one around

See my post below: (Sorry, we're in the same boat)

Hunter ceiling fan with remote, have 5, 4 are seriously impaired! Lights dim to half strengh after variable time 10 seconds-30 minutes. And lights or fan turns on randomly (come home & fan on full blast), and one in which the lights won't dim (just blinks when try to dim)! Hunter "kinda" admits there is serious problem with remote but doesn't have a solution. Tells people to try changing to different code due to possible interference (pain in **** to change code on ceiling base!), was totally ineffective. Then replaced receiver in ceiling base (another total pain) in 3 fans with new ones sent Hunter, still totally useless. Hunter's suggestion, don't use the remote, just use the pull chain. If I had wanted a pull chain fan, I'd have bought a pull chain fan. TOTALLY USELESS! Moral of story: If you want a remote ceiling fan (my friend found out that all their remotes are made by the same company in Taiwan), don't buy Hunter!!!!! P.S. I found a "Kinda"- fix for the lights dimming to half strenth. After turning on the lights, wait 1 second, then dim lights slightly, they will then stay on the strength that you dim them to. - P.P.S. When I changed the receiver in the one where the lights won't dim, it "solved" that problem...Now it has the same problem as the others, lights or fan turn on randomly!

How do atom the smallest particles of matter form

Hi,

The current view is that atoms are made up of protons and neutrons (which in turn are made up of quarks and gluons) and electrons. The protons and neutrons are at the central core called the nucleus, and the electrons revolve around it, being held in orbit by the electromagnetic force between the negatively charged electrons and the positively charged protons in the central nucleus. It is very much like the solar system with the sun at the center and the planets revolving around it. They were formed right after the "Big Bang" when our known universe originated from pure energy some billions of years ago. The energy was converted to the elementary particles (quarks, gluons, leptons etc...) from which protons and neutrons were formed. From these, atoms of different elements were produced.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

Yamaha Virago Cutting out in the wet

Hi,

I had the same problem with mine. Its a dodgy ignition coil i found a spray of wd40 on it would fix it for a while by driving out the moisture. I've since put a piece of plastic bag around it which helps alot. Should really give in and buy a new coil though

Briefly explain the nature of the tech support job

basically it's helping people with similar problems that are posted on this website! However, different companies focus on different things are their set up is obviously different. Usually support revolves around helping using with their applications such as MS Office and configuring email. More advanced Tech Support Jobs would have you manage SQL server or install and configure system wide changes to Anti Virus, for example.

I hope this clears it up for you.

Re: possible solution for the 9000 errors.

Ohhhhhhh yes,

Clean under and around the bobbin case regularly.....my wife has a small brush to hand, and does it at every bobbin change.

The quilters of the world need to be especially vigilant, as the wadding and layers generate lint at a remarkable pace.

As to bobbins, they do vary from brand to brand, diameter and height, so this can be an annoying apparently "intermittent" problem if you happen to have a few different brands kicking around.........I had one customer who had me on 3 house calls before I realised that she had been collecting blinkin' bobbins where and whenever !!

Another thing with the brown magnetic donut in the middle of your white hook race.........best to use Janome plastic bobbins to avoid any other troubles, rather than the older metal bobbins.

Glad it all went well.

Cheers
