Question about Heating & Cooling

2 Answers

B & D company air conditioner(model# 566DJ024-C) makes buzzing noise. I just bought a house and when I turned on the air...the unit outside makes a buzzing noise. The fans seems to work and cooler air is coming out of the vents(only ran it for a few min,didn't want further damage). I had the home inspected and the inspector said that the inside breaker is 30amps and the actual max for this particular unit is 25 amps. I don't know if that is the problem or something else...just thought I'd mention that.

The circuit breakers Ampere rating has nothing to do with the buzzing noise. If you use a lesser Ampere Circuit Breaker it will trip every time the Air Con: starts, and if you use a very high Ampere Circuit Breaker it won't trip and give you the needed protection - after all Circuit Breakers are supposed to prevent damage due to overload.The ideal value should be 20% higher than the Air Con's rated value.The 20% extra is to cope with initial start up surge.
The buzzing noise could be because of two reasons . If the Air Con was not used for some time the rubber mounting bush could have hardened. The rubber bush is a shock absorber or an isolator which prevents the compressor motors vibration from being transmitted to the body of the Air Con.Just like your car shock absorber but not that sophisticated !!.Just 4 rubber rings or pads.
The second reason could be the radiator fan which is for cooling the condenser pipes and fins.There could be something lodged inside ( bird nest etc: ) touching this fan. You can remove the fan grill and see for yourself.
Any way if you are getting cold air inside it means all is OK (no gas leak, compressor working ,room blower working and copper pipes not damaged ) , just that the buzz could be irritating and should be sorted out.

Hi, the buzzing noise could be related to a low voltage or high voltage transformer problem that may have been the source of your A/C problem, it could also be a relay of the compressor which could make the buzzing sound.

My goodman unit (1994) makes the loud noise, like a buzzing noise. The unit works, the blower blows air into the house, the air is cold, but the outside fan that blows across the condenser piping isn'


you need to replace your condensing fan motor. the noise you are hearing is the compressor working against a lot of pressure because the heat is building up in you condensing unit. Prolonged operation without an operating condensing fan motor will cause your compressor to burn up, and then you will have the cost of a compressor changeout to the cost of a condensing fan motor.

I need help with a buzzing sound in my air conditioner.


It is probably the compressor humming. They can make some funny noises especially on start for a while. If the unit is not cooling it may be the start capacitor or the comressor may be locked up.

The outside heat pump makes a continuous buzzing noise along with a short intermittent louder/lower frquency buzz noise... the fan never turns, the house attic unit fan runs but the house never cools. ...


Sounds like your condenser fan motor (outside unit) is 'froze up.' Bearings are probably bad. I would suggest having a Service Tech check it out.

Not much you can do yourself - maybe look for an obvious loose wire or something (if you do this be sure power is all off).

It's possible a 'fan capacitor,' (a small grey/silver thingamyjig about the size of an oversized cigerette lighter) is bad - (it will have a wire from the fan motor going to it) but - "not likely."

If it (fan cap) is bad - sometimes they will 'bulge' which is a dead giveaway that it is bad. In which case you could take it down to an AC parts house and get a replacement. If you do this - be sure 'all power is off,' and you mark the wires when your remove the old fan cap - and buy an exact replacement - so you can hook it back up correctly.

Again, the most likely problem is that the fan motor itself is bad - and needs replacing which will run about $200 if a Service Tech does it.

Note: it's possible that you have a 'blown fuse' or a 'tripped disconnect,' on your outside unit - so - I would make sure that your 'fuses/breakers' are all good too.

hope this helps

Fan not working on outside AC unit


The buzzing noise is probably the fan motor. Is the compressor running? First make sure that there are no tripped breakers. After that kill the power and check the capacitor with a multimeter. If that checks good then check the fan motor windings with the multimeter. Let me know if you have any questions.

Fan will not work on outside unit.


Check the voltage to the contactor coil, it will do that if the voltage is low. This is the 24 volt part.

Outside Unit blowing air but not cooling and slight buzzing sound


The compressor is not coming on and some part of that unit has failed. Do you hear any clicking sounds along with the buzzing sound? Recommend that you shut the unit down (remove power from it) until a service tech can listen to it try to start up.

The power company-installed load management system is probably a red hearing. That system will either fully turn off the unit or allow it to turn on/start up.

Fan not blowing


Even when the power is off at the unit outside the thermostat will supply power to the contactor of the outside unit. This may give a hum or buzz as you stated. If when the power is on to the outside unit the fan tries to start but only hums the motor may be bad. Does the compressor start and run?
