AC compressor Buzzing
Hey all, I have an old Kenmore outside AC only unit. And i just got in
this house.. from what i hear the ac unit has been "broken" for about 10 years. Why? I dont know. Basically what was going on is that the outside fan on the unit comes on fine and the inside unit fan blows the air.. But its warm.. So i check the compressor and hear that its buzzing for about 3 seconds every 10 seconds or so. I call a technician out and he looks things over. He tells me that it just needs a hard start kit and the price would be 600$.. That seems a bit excessive to me. He did not check freon level and i was wondering also.. If these are anything like a cars ac compressor.. If the freon is low will it even start? Or will it start and just not cool? So im kinda wondering about that. Basically though i spent 50$ for him to look over a few things.. not test anything mind you and he listened to the unit. and the buzzing.. So his diagnosis is a hard start kit. What do you all think? |

If you have problem with that, go to
http://myhvacparts.com/Catalogue/Air%20Conditioning/ and then select Hi Power Hard Start. Purchase price on the item is $45 Worth checking out.

AC compressor Buzzing
And a lot has happened with AC units in the last 10 years, your unit
could have been 10 years old already when it crapped out. If it were me, I'd consider Mark's suggestion. Probably after giving a hard start kit a try, though. Here's another source, even less cost. http://www.azpartsmaster.com/shopazp...d%20Start.html No warranties, expressed or implied Mark wrote: compressor is trying to start but is stuck so it is not starting and is cutting out on the thermal cutoff..., like a motor with a locked rotor...thats the buzz you hear...a hard start kit may work for a while but if the bearings in the compressor or whatever are just getting worse, then even the hard start kit will eventiually not start it, a hard start kit is just a bigger start capacitor and sometimes works for a while sometimes not.... I would get the compressor replaced or just get a new unit. Low freon will not cause this problem in a home unit like it does in a car... Mark |

I've seen this problem too many times to count. Go ahead and waste your money if you want. A run cap is MUCH cheaper and is the first thing you should replace. Yes AGREED Good point! Mark |
