Goodman Condenser - Heat - Buzzing Noise every 60 seconds
I have a Goodman Condenser unit on my heat pump thats about 5 years old. Recently I noticed an intermittent buzzing noise coming from my fuse panel and I was able to correlate it to my Heat pump turning on and running. When it first turns on for heating and thereafter at an interval of every 60 seconds it makes an electrical buzzing noise at the condenser unit, this causes a similar noise at my fuse panel. It sounds like an electrical short, but the breaker (40 Amp) never cuts off. I've turned the unit off since it's only used to heat the basement.
What would be causing this? Seems to be very specific to a 60 second timer in the condenser unit.

You stated capasitor was checked . if cap. is ok sometimes start terminal wire will burn into at compressor or you may have a loose connection causing a voltage drop (more than 10%).If both check ok try a hard start kit. Who knows it might start. good luck

It could be your compressor trying to start but not being able to do so. It shouldnt happen that often but in cold temp the overload protector may cycle that quickly. I reccomemnd to have it checked to salvage the expensive compressor.

Take a look at this YouTube page that explains with good videos what are some of the common problems with heat pump noise. The one that seems dominant is the defrost cycle a heat pump goes thru when it melts ice off the evaporative coils. In defrost cycle, The compressor runs but the cooling fan does not, so you will hear a loud buzzing sound and the unit sounds like it is stalled...because only the compressor is running to generate heat to melt coil ice.
Taking a little bit of time for heat is normal but the "pressure" thing you are referring to leads me to believe that the reversing valve is getting stuck. You will here that "pressure release" noise with a reversing valve but it should not be happening 5 minutes after start up.
Hello, Usually it has to do with the quality of the install and the brand. If it was not installed properly from the beginning then the equipment will fail prematurely. As far as the heat exchanger goes I have replaced many heat exchangers on Goodmans after 3 years being installed, Goodmans are prone to bad heat exchangers.
I don't think this problem (btw I agree 'from a far distance' with the Hvac guy) is inherant to Goodman, after all the compressor (that is in the unit) is one that if found in other brands too.
Of course the compressor is under warranty so there's no charge for it - but - $800 to change out the compressor (and that's the proper fix) is a 'bit' high - you possibly could save a few bucks by getting some other estimates.
Without being there to see it and have only your description in front of me, it sounds like the fan blade could be out of balance.......but it sounds more like a loose fan blade hub. Most Goodman units offer a minimum 5 year parts warranty. The Labor warranty is questionable, but the installing contractor or the Goodman Distributor should be able to give you that information. Of course this would cover manufacturer problems and not physical damage. As far as a history of this problem with Goodman..........I've seen it with every brand. If there is a problem getting it under warranty, you might be able to purchase the blade yourself. Before replacing the fan blade, I recommend disconnecting the motor wires from the contactor, tape off the ends and remember exactly where they were attached.....then start the unit to see if the noise is still evident, if so, it's probably your compressor. I recommend a certified repairman....not the one that quoted you $800.00. If you hear only the compressor start up and not the loud noise you are discribing, then try replacing the blade first.
I hope you find this information to be very helpful to you. :-)
I dont know where you are located but anything bellow 45 degrees a heat pump does not put out much heat. As it gets colder the effeciency goes down. So if you have 24,000 at 60 degrees outside at 45 it is 15,000. Now first thing have the charge checked. If a unit is one pound low it can loose 20 %. Next see if your auxilary heat is working . You have at leat 8 KW backup heat.This comes on the second stage about 2 degrees or 2 to 4 minutes behing the Hat Pump. Ask service tech for free estimate or call and get season check. They will go thru your unit and check everything and let you know what wrong and also clean the system. Cost about 49.00 to 69.00. I own a business and we sell a maintanance contract for 105.00 and check and clean the system twice a year.Keep in touch Rus
Depending on the size of your Electric heat you can use one set of wires because your unit does not run with the heat like the heat pump. The large set of wires going to the electric heat should be used. You may have to jumper a new set to the contactor. On Goodman unit come in L1 and L2 jumper to contactor. Very simple good luck. Rus
ok...where to start.lol ....the thermostat is just a switch.It will tell the unit to run or not run.if you measure the temp with the heatpump running,the air is warmer than 68 but it feels cool to you because your body is 98.6.The unit will run more often and for longer periods when the temperature drops outside for a few reasons.First,your house has more of a load to heat,meaning you have more heat loss because of the difference in temperatures outside and inside.Second,your heat pump pulls heat from the outside air.The colder the air outside,the less btu's for it to pull.If you have anymore questions firstname.lastname@example.org Hope this helps,Dave
