Question about Ruud UAKA030 Air Conditioner

Buzzing on unit

I have a UAKA-037JA Ruud AC unit. I just bought the house. No one has lived in the house for about 2 years. When I turn on the t-stat to cool the unit just buzzes. Air is coming out of the vents but the unit is not cooling. I pulled the service panel to see if anything looked wrong. I didn't find anything. Is some part of the unit shot?

Is the buzzing in the outdoor half of the system? If so
your possibilities are.
buzzing could be the contactor. In the control compartment on the side of the unit there is a small brown component that has wires to one side and the other . There are contacts in the center like points on a car. If the points are pulled in look for ants in between the contacts. Always secure power to the outdoor unit before touching anything inside. If the points are pulled in check your breaker to the outdoor unit. Turn the breaker off then back on. Breakers sometimes trip but look ok.
Buzzing could be thee coil to the contactor itself, sometimes with age the coil will breakdown and cause noise.
if you give me more information I can focas in closer to a solution

Ruud UAKA-030JAZ fan spins, not blowing cold air


there are 3 things to be considered,first,if the compressor motor `s connectors are having loose,it gives a hi ampere to your RELAY that can cause to its contacts being fried,second,the compressor motor itself is gaining a hi ampere already i.e. having unusual sound that can cause heavy friction inside the turning mechanism and third the last but not the least,maybe this time,the tubes or the compressor itself having very small holes that causes to the refrigerant to escape and it doesn`t gives off cold air.

I have a Ruud gas furnace. We just replaced the transformer and the capacitor in our ac unit. The heater now works but the ac does not. The compressor doesn't turn on at all. Everything worked last...


Go to your outdoor coil (condensor) and remove the cover where the electrical cord goes into the unit. You will see a cont actor with two smaller wires and at least two larger wires. Take an INSULATED screwdriver and push in on the contactor. Does the AC start when you do this? If so you have a 24VAC control circuit problem. Your T-stat closes that contactor when you call for "cool". Let me know what you find.

My totaline digital 2 stage thermostat keeps buzzing. I have to turn the whole a/c unit off to get it to stop. Lately it hasnt helped much as when I turn it back on it is still buzzing. Help


Hi, relays will also buzz causing units to loose transformers, I have seen this in the past years also. A 2-stage heat-pump stat? I would remove the front to expose the wiring terminals and pull the hot wire red, 24 volts and that should kill the buzz. If so, the circuitry is going out and you will need a new thermostat. I would, if you have a volt meter check the incoming voltage to the stat to make sure it doesn't exceed the proper voltage rated on the cover. Max would be 30 volts ac. If its over that, the transformer is putting out to much on the secondary side and should be replaced, or it will eventually take all of the low voltage controls out. Try removing the 24 volt hot wire and also if you have a friend that has a meter or you do, check the voltage coming in to the stat. Get back to me if it exceeds the rating, as this will cause the buzzing. It may just be faulty contacts in this stat also. I wish you the best, and ask that you are kind when rating me in helping you. Please keep me posted if you need my help.
Sincerely,

Ruud uhqa sill runs when i turn off t stat contactor test good and is not stuckhit breaker and back on and fan stops running goes on when t stat is turned on stays on till i trip breaker again i think it...


Your sentence is hard to understand because there is no punctuation. But, I think you are saying that the Outside unit is still running when the inside unit is off and the Thermostat indicates it should be off. If so, you have a stuck relay outside in the compressor/condenser unit. This is common. The contacts get hot and fuse themselves together. You will have to remove the cover on the unit outside to expose the relay. MAKE SURE THE BREAKER IS OFF. If you house is to code there will be a disconnect box on the wall just above the AC unit outside. PULL THE DISCONNECT> then use a flat head screw driver and slight pry the contacts apart. If they are fused very tight you may need to replace the relay. If they break free put every thing back together and you're done. If you this happens again soon you will need to replace relay.

We need an owners manual.


Hi, looks like you have a 21/2 ton Ruud split system by the numbers. Let me look this up and see if I can find a manual for this unit and send you a link to down load it. Give me sometime please. Be back soon.

Have a Ruud Achiever Model number UAKA-037JAZ that won't run since yesterday. When the air kicks on it simply makes a buzzing noise and the fan doesn't spin. Can anyone help?


try spinning by hand when the unit make the buzzing sound. to see if the capacitor is bad. If the fan runs replace the cap. If not motor probably is bad. See if it spins freely. this is a good starting place. need to check if the buzzing is the contactor and there is no power to the condensor. The contactor will buzz even though the main breaker is off or tripped
