In this video you'll learn why your dryer may be making a variety of ... that is not only making a grinding noise but it also makes a loud banging noise. ... it's been drying about 15-20 min. it startsa loud humming sound. ... The dryer is working just fine, but I am concerned about the noise as it sounds electrical.
You might have a short going to your reversing valve. Check the temperature of all three lines out of the valve. The one on the left should be cold and the one on the left should be warm hot. . Check voltage to the valve.if it fluctuates that might be the reason for the buzz.
check all wire connections to the battery and the starter and check the battery for being a good charge. the buzz sound is from not enough voltage or current getting to the starter.
The electrical box on the new a/c unit is what is buzzing? If so then thats the contatcor making that sound and is nothing to be too concerned about. If that buzzing is coming from your breaker box then turn off that breaker and call an electrician.
The buzzing sound, along with the fan motor not running, usually indicates low voltage to the contactor and the contactor is not engaging or closing the points and it usually buzzes when this happens.
You first need to check and see if you are getting 24 volts to the contactor coil. You should at least have 21 volts, if not check for loose or dirty connections, if none, check the voltage at the transformer to see if you're getting 24 volts there.
It's one of these things: The battery. Especially if you're still using the original one, which is now almost 10 years old. The charging system. Or the starter relay.
Even if your battery isn't 10 years old, if it has sat for more than a month or so without being charged, then it is toast. A fully charged 12 volt battery should show about 13.5 volts on a volt meter.
If the battery is good, then you will need to find out if the charging system is working. To do this, you will need an ampere meter capable of reading up to 10 amps. Start the engine and THEN hook the amp meter in series between the battery (either side) and the cable going to the battery. With the engine revved up to around 4,000 RPM, the charging system should be putting out at least 5~6 amps.
If it isn't the charging system or the battery, check for a bad starter relay (the thing that makes that buzzing sound when you hit the starter button). Perform this test by bridging across the two large cable connections on the top of the relay with a large screwdriver. If the starter spins when you do this, then you've got a faulty starter relay. If the starter doesn't spin, then you've got a bad starter motor or a bad electrical connection going to it.
sounds like the input to your hifi is a line level input.to use an old turntable you need a phono pre amp to make it work.try maplins or a local independent hifi shop.
Hello to all you buzzers, I have the answer to your problem. First this is what's happening. The buzzing is coming from the power relay. It vibrates at 60hz because the power supply filter capacitor is not doing its job hence you have a rough d.c. pulse going to the relay.To solve the problem remove back of t.v. slide circuit board out (you will have to disconnect white wire from degauss coil,located on left front) look for a blue box approximately 3/4"x1 1/2" this will be the power relay. Now look for capacitor location #c622 near the relay. This capacitor should be 470uf 25v. Remove and replace with 470uf 35v capacitor, connect white degauss wire temperarily put back on and give it a spin. Hope this solves all the buzzin,robert
