Question about Goodman Air Conditioners

1 Answer

I have a Jantrol heat pump & A/C. It is approximately 10 years old. For the last 3 summers the compressor unit will freeze when the air handler fans fails to come on. It worked fine for 2 weeks this year before it happened. I've be able to thaw it out and restart the unit and it works from days to weeks before this occurs again. The last time it happen, I had a problem getting the air handler fan to come back on, but it did eventually. I've been thinking it may be the sequencer, but now I'm wondering if it could be the capacitor?? or a lot of things??

Hi,

If you can safely check the supply to the motor when it should be on, then this is the best method to check it.

Check the fan turns very freely - oil the bearings if it doesn't.

If there is power there, but it does not turn, replace the run capacitor.

If this get's you going - Please rate as Fixya so others may benefit. Thanks!

as most ac units are capillary tube control not tx valve having matched units is critical. as for cost the condensing unit is much more complex and expensive than the evaporator.

Heat pump problems


Some heat pumps have high and low pressure swiches installed to keep compressor from running when unsafe conditions occur that can damage the compressor. If the outside fan is not turing on, the unit is cycling on high pressure, if you see ice forming on the big refrigerant line coming from the air handler, then the compressor is shutting down on low pressure. Low pressure can be cause by lack of air flow through air handler or from a low refrigerant charge.

Ac unit keeps freezing up


what a heat pump is designed to do is reverse the evaporator inside coil and condensor outside coil. it trys to pick up heat from outside and transfer it inside. they work fairly well down to about 40 degrees ambient then not so good. that is why you have auxillary heat i.e. 15 kw. when it was shaking as you saw the compressor is trying to pump liquid instad of vapor as it's designed to. you either have a control issue or it's overcharged.

The condenser unit will not kick on...it is a concord unit,10=12 years old,13 seer,3 ton. The air handler works fine. I thought it was the capacitor. The old one was bad,I verified that with multimeter....


It could be a low refrigerant cut-out (switch), grounded or shorted motor windings, open internal winding overload protector (check at the common winding), a broken conductor, or no power at condensing unit from blown fuses or open/tripped breaker.

HE heat pump won't talk with old air handler?


The fact is, the air handler supplies the voltage, blower, and electric heat. In order for the heat pump to work correctly, the wiring from the thermostat and heat pump need to be hooked up right to the air handler. The thermostat is what tells which component to come on. If the fan stops, but the condenser keeps going, you either have a faulty fan relay on the air handler, faulty thermostat or wiring, faulty wiring at the heat pump, or the contacts on the new unit are sticking, which is highly doubtful considering it is working now. I hope I have helped you understand this a little more. Good luck and don't let them push you around, get someone that knows what they are looking at.

Goodman Air handler blowing fuse if switch outside unit not runni


Sounds like your compressor in your heat pump is siezed . You can try a "Hard Start" Capacitor...which basically gives your compressor a kickstart and works 95% of the time when compressors get older....It's hooked up in parallel with the existing Capacitor...if you're not familiar with Electrical etc I would call an expert and mention what I said . If this doesn't work you will likely need a new Compressor/Unit . You could also have a short to ground in the heat pump side....likely the compressor is the problem however the original Capacitor could also be the problem

I have a Ruud air-conditioner/heat pump and it blows 5 amp fuse.


It sounds like the thermostat wire going to the condenser is ground, It either got pulled loose and is touching the housing or as in most cases the wire got cut or was chewed by an animal. You need to turn electric off to both devices and physically inspect the thermostat wire going from the air handler to the outside unit, also inspect where they connect inside the unit. When you find the break, cut and strip each individual wire and securely wire nut each conducter red to red white to white and so on. There you go all fixed. That's when I give you the bill for $75...except this time you write that check to yourself. Good Luck

Hunter thermastat, model 44860 not working


Is the compressor running? is the outside unit clean and free from debris? does this unit work in the heating mode during the winter, and is it still capable of that now.

Cost to replace carrier 38ckc060


Did your unit work last summer? 10 Years old is very soon unless it is a cheap unit like janitrol or goodman. Most units last min. 15 years and 20 most of the time. Generally speaking any ways. To replace compressor cost maybe 750.00 to 1,000.00 you have a big house looks like. 5 Ton unit. The whole system could be 6000.00 to 8000.00 depending on grade of unit. I would get a second opinion though cause I am wondering if they are just padding their pocket.
