Cooling the shop.
I just got back from Californy today, where I had a nice birthday
(59th) with family. Home and shop A/C was working fine until about 6pm when I felt warm air coming out of the vent. Aw****. Took a listen outside and the condenser fan wasn't running but the A/C was. Hmm... Took a VOM out and found that the two fuses were fine and there was 239.8v across them. OK so far. Felt the top of the condenser fan mount and found it very warm. OK, it's 90 out, it'll be warm in the sun. I showered it with cool water until it was cold. Popped the bolts loose and the fan spins freely, no frozen bearings. It has a 60Hz hum feel to it so I think it's being (somewhat) energized. VOM confirms that below. Start relay has 24v from the thermostat and 119v through each contactor and through the start cap to comp and fan. Looks normal so far. Then I heard a click and the compressor sounded like it labored for just over a second before the second click happened. It was fairly quiet. I've never troubleshot a compressor system in a house, but it sounded like the comp might be frozen. I took auto A/C in school in '72 so it's very familiar in concept. I see that there is a high-pressure switch (probably not engaged), low pressure switch (dunno without gauge set), and thermistor switch (now cooled with water, so doubtful as the culprit now.) System is ten years + 4 months old and has never had a problem. I have the installing company come out almost every year for a checkup but didn't last year. They found a loose squirrel cage early on and some pieces of insulation in the fan another time, but nothing else has been required or done to it. Any thoughts, boys and girls? -- A mind, like a home, is furnished by its owner, so if one's life is cold and bare he can blame none but himself. -- Louis L'Amour |

Maybe the capacitor went bad. Start cap. Sounds a lot like it. yep. Mine did this earlier this year. Cap is normally bulged if it broke. Very low cost thing to try at any rate. Karl |

Try the inexpensive options, first. Replace the run capacitor.

They found a loose squirrel cage early on and some pieces of insulation in the fan another time, but nothing else has been required or done to it. Any thoughts, boys and girls? Was the condenser fan spinning when it tried to start? If not, then the condenser pressure built up until it tripped the high pressure cutout or overheated the thermal switch in the compressor. The unit will need to cool off before restarting. Cooling the compressor may take several hours. It could be a bad start or run capacitor. Usually these make themselves VERY obvious because the explode smelly stuff all over the inside of the condenser cabinet. After cooling off, turn off the disconnect by the condenser, and then set the thermostat inside to make it run. Watch and listen when you turn on the disconnect. Does the condenser fan spin? Does the compressor make a locked rotor loud hum, or sound like it is spinning? or, does it just fire up and run OK now? If the compressor sounds like it is laboring badly or locked, shut it off immediately. If you can't find a blown capacitor (may be inside an inner compartment) or bad relay, then you may have to call for service. Jon |

As long as the compressor runs, you can put a box fan on top of the unit and get by... You can get WAY more cooling using a garden hose and a spray nozzle. I once ran my 5 hp. apple cooler all weekend this way. Karl |

System is ten years + 4 months old and has never had a problem. I have the installing company come out almost every year for a checkup but didn't last year. They found a loose squirrel cage early on and some pieces of insulation in the fan another time, but nothing else has been required or done to it. Any thoughts, boys and girls? Was the condenser fan spinning when it tried to start? If not, then the condenser pressure built up until it tripped the high pressure cutout or overheated the thermal switch in the compressor. The unit will need to cool off before restarting. Cooling the compressor may take several hours. I cooled it to 60F in minutes with water. It didn't restart nor did the fan start. I checked it again a few minutes later, and no internal heating was found, except in the 4 nuts holding the fan on. It continued to heat mildly, like it wanted to start but couldn't. It could be a bad start or run capacitor. Usually these make themselves VERY obvious because the explode smelly stuff all over the inside of the condenser cabinet. It may have leaked, but not much, and no explosion. I got enough oil on the rag to make a 2" spot, altogether. Not much oil, and nothing inside the cover or down the panel it was fastened to. If it did overheat, it just seeped a wee bit of oil after doing so. After cooling off, turn off the disconnect by the condenser, and then set the thermostat inside to make it run. Watch and listen when you turn on the disconnect. Does the condenser fan spin? Does the compressor make a locked rotor loud hum, or sound like it is spinning? or, does it just fire up and run OK now? If the compressor sounds like it is laboring badly or locked, shut it off immediately. If you can't find a blown capacitor (may be inside an inner compartment) or bad relay, then you may have to call for service. I heard the relays click on the thermostat. Then, every 5 minutes or so, there was a quiet click on the compressor and a suppressed hum for about one second before it clicked again. The fan never spun. I didn't try it with the 240v disconnected, though. One other thing: It was cooling well earlier yesterday. It's not like it has been degrading for some time. If I was barefooted and the A/C came on, I put on socks immediately. -- Another belief of mine: that everyone else my age is an adult, whereas I am merely in disguise. -- Margaret Atwood |

Good thing you didn't have a 5 HP PC cooler.
I used a box fan inside a walk in cooler, one time. It's still there, and works fine. Christopher A. Young Learn more about Jesus www.lds.org .. "Karl Townsend" wrote in message ... As long as the compressor runs, you can put a box fan on top of the unit and get by... You can get WAY more cooling using a garden hose and a spray nozzle. I once ran my 5 hp. apple cooler all weekend this way. Karl |

It's not like it has been degrading for some time. If I was barefooted and the A/C came on, I put on socks immediately. Oil filled caps don't degrade, they either go open or short. Bipolar Electrolytic capacitors develop high ESR before you can detect a change in capacitance. That reduces the current through the capacitor and causes it to heat. Not that you'll see any of this. |

Bad juju !! Snag, some people will never learn to do things right. I've had two electrical fires because people half assed repairs, or reused old equipment that they should have thrown away. This property was bought from the widow of a 'Precision fixedit' type that worked for the schoolboard. He dragged home whatever he could from the scrap pile at work to 'fix' things It's taken over 10 years to rip his crap out and do proper repairs. Actually this was original construction electrics . He has since had a nice new breaker box installed . With capacity for expansion IIRC . -- Snag Learning keeps you young ! |
