Is it the outside unit ofr the inside... either way sounds as if the blade is hitting the fan shroud. you should be able to access unit to see exactly where noise is coming from.

What could be causing loud grinding noise when i switch on aircon? Aircon now not working but only makes loud sound.


Sounds like the bearing or part of the clutch in the A/C compressor has failed, or possibly component on a/c fouling on something due to recent repairs however would be unlikely and probably just a coincidence..

Check A/C compressor turns by hand, should be firm but not make any noises.

Check for fouling components related to a/c compressor clutch.

2 and 1 aircon error ch 05


Try resetting the system. First turn the breaker off for the condenser and wait about 20 seconds. After you turn it back on the system should reset. If you have any other Air Conditioning Repair Questions don't be afraid to let us know

I have an old zenith sentry tv, and up to know has never had any problems. Afew days ago it started making a very loud noise as soon as I turned it on. It sounds like it's coming from the right


someone needs to open it but it sounds like a part arcing which was not uncommon in those sets====you would have to decide if you want to attempt to have it repaired----some shops will not repair a set that old and unless you really want it done---I would replace it.

AVR SR6004 switches off while BD player is playing. What do I do?


Hi,
There are two circumstances that I know of that a properly installed unit such as your Marantz would shut down. So here is the Theory and Data I know of.
A Your receiver has a great deal of amplification power. If it is in a closed cabinet without excellent ventilation, it will shut down if used at high volumes because because over heating. Because of it's very high power, when played loudly, it generates excessive heat.
When watching certain movies the BD player may be over-driving the limits of the amplifier section of your receiver. Page 78 of your owner's manual addresses this. Here is a link to download the manual from Marantz.
http://us.marantz.com/us/Support/Pages/Manuals.aspx
B There is one other very important thing I should mention to you. When people use high powered equipment and initially turn up the sound. After a short time, the mind turns it down. What next happens is the reason professional musicians and sound engineers often have permanent hearing loss after a relatively short time.
What tends to happen is that the listener and often the engineer running the sound mixing board at a concert(after a certain period of time) believes the sound is not loud enough when it really IS loud enough. (this tricks the audience as well) and engineer turns it up. After turning it up, his mind (and the audiences') turns it down mentally and they again think and agree that it not loud enough and then again, the volume level is turned up. And up. And up. The only reason I'm not deaf is that I discovered this when I was building sound systems as a kid. I also studied about it. So please be careful when you play things loud. Permanent hearing loss starts to occur at the very high frequencies and rolls down from there over a period of time. Hearing loss can start to occur in just a few hours at 110 decibels. permenant hearing loss is exactly just that. Permenant! It just doesn't come back. If you use this information, you will enjoy hearing music for the rest of your life.
I hope this helps,
Best Regards,
Mark

My aircon unit turns on runs for a minute then indoor and outdoor unit switch off


If this is a LG Airconditioning unit.
It has reached the set parmeter of the safety switch point.
1 The unit could be running on too low refrigerant charge and cuts out on low temperature on the indoor unit coil (-5°C longer that 30sec switch off)
2 The unit might be drawing to much current, to much refrigerant, cutting out on high pressure.

Check the refrigerant charge and check the indoor pipe temperature thermister (calibrated at 5kΩ @ 25°C)

Loud Popping Sounds


If this is a heat pump system it is possible that your fan blade is hitting ice on your condenser coil.
