Air Conditioner compressor Humming sound
I have a Lennox 10 ACB Compressor system. I noticed today that the Air
compressor (external) was making a humming sound and the fan was not working. The rest of the Air Conditioning system seems to be working fine. Any suggestions on how to resolve the above issue. Regards AT |

Don't get yourself electrocuted. |

Could be the motor, could be a capacitor, could be a few things. If you don't know how to diagnose that stuff, call a service tech.

Call a repair and service company immediately. The next step
in the process, is that the compressor stops humming, and the repair gets a lot more expensive. -- Christopher A. Young Learn more about Jesus www.lds.org .. "AT" wrote in message ...

The rest of the Air Conditioning system seems to be working fine. Any suggestions on how to resolve the above issue. I'm guessing the start capacitor is kaput. 1. Turn off power. 2. Take several pictures of wires connected to capacitor(s) 3. Remove capacitor. 4. Take capacitor to A/C parts store and say "Gimme one like this" (Higher voltage okay) 5. Install new capacitor 6. Turn on power. 7. Does it work? 7a. Yes, you're done 7b. No, call reputable A/C tech |

You may have a breaker that is tripped, and the relay ( contactor ) is making a humming noise. ( Note: The contactor is powered from the inside unit.) If the compressor is buzzing it will cycle on and off. Check the breakers. You could have one inside the house and one out side. The one outside may be a fuse type. |

Regards AT The rest of the system could not be working fine if the outside fan was not blowing air over the condensing coils to liquify the refrigerant before sending it back to the A-coil in the blower unit inside the house. That is assuming you have a conventional system. |

When our Lennox did this a couple of years back, it was the capacitor; more precisely, it was one of the two capacitors in a single can. I had a meter that allowed me to check it; if you don't, maybe you could just remove the capacitor (take careful note of the connections) and take it to an a/c service place and see if they will sell you a replacement. Don't remember how much I paid, but probably less than $20. Perce |
