SOURCE: Won't heat or cool

as a general rule you sound like you have a compressor that is mechnically locked up. in other words it can't free itself from a stationary position and begin pumping and moving the piston. this is caused by one of several things. first kill power ,and carefully, and methodically examine all wires and terminal connections. be sure all are clean , snug and not burnt off etc. even the ones attached to the compressor itself. the compressor wire cover comes gently off and is usually held in place by a spring clamp be sure to replace when your done checking. if all wires check good then go to step two. that is a check of the capacitors. the silver metal large capacitor is the run capacitor. it keeps the compressor power in the windings out of phase so it runs same way everytime. it has a rated value stamped on its side. it should check with a volt meter that checks capacitors at not less than 90 percent of its rating . a 60 needs to check no less than 54 microfareds. etc. some capacitors have a common input side and a dual output side. they are labeled on top where the wires connect.one goes to the condensor fan and the other goes to the compressor. the larger circuit ,common in, to herm out is for the compressor. if in doubt label all wires , make a diagram and remove it and take to an electric motor shop and let them test it. in addition to the run capacitor that keeps the compressor going, you may also have a start cap that is usually black plastic. they have a" Yes by gosh you will" start function and store up voltage and deliver a powerful boost on start up to make the compressor get going. it can be tested the same way. be sure to ground the capacitors before testing after power is turned off by shorting across the terminals to bleed off any stored voltage. , with a screwdriver blade. by the way if you look at the silver run capacitor and its swollen up or bloated looking then its bad. you'll know what i mean if you ever see one. looks like it has the mumps. they really puff up. top and bottom should be normally close to flat. if all that checks good then you must apply and amp probe to the black wire going to the compressor. when it tries to start observe the amp draw. if it is like 48 to 65 amps then the compressor is mechically locked up and probably needs replacing. if you don't have a plastic hard start capacitor and relay you can add one and it can many times break the compressor loose and you can get a few more years out of a compressor thats getting weak. try a T05 hard start kit or a KS1 hard start kit. to5 for up to three ton and a ks1 for 4 and 5 ton. simple to install .be sure the start relay is positoned correctly, instructions are on the package. good luck let me know outcome.

SOURCE: lg minisplit heat pump will not heat

You may want to check that the pressure switch is not functioning? Secondly there is also a thermo sensor on the condenser coil which could be faulty.

SOURCE: heat pump not running

check your house circuit breakers first that should be labeled heatpump or outdoor unit
make sure it is on and or not tripped
then if you have a box outside near the outdoor unit open it up and see if there is a breaker or maybe fuses that could be blown

SOURCE: i have a goodman heat pump and i suspect a bad reversing valve

Sounds like reversing valve is stuck or metering device or check valve is stuck open. If it is a scroll compressor on 3 phase you may need to reverse 2 motor leads. try tapping reversing valve with rubber mallet when running. This may have done in last compressor by sending discharge gas to suction side.

Heat pump fan only running air handler fan only running was working fine quit last nite now no heat but both faans running


Compressor must not be running. Possible capacitor, possible low pressure. Check it in cooling mode and listen for sound change out side to see if compressor runs.

When the heater is on, should the fan outside on top of the unit also be working along with the blower from the heater ? When the heater is off, cold air is comming from the vent's, can I cover the


No. This is strictly a gas package unit, not a heat pump. the condenser fan motor should NOT run when their is a call for heat from the thermostat. The condenser fan only runs with the compressor on a call for cooling. Hopefully the compressor is not running @ the same time, but if it is, it would make sense that the contactor for the compressor & condenser fan motor is stuck closed OR the low voltage cooling wires are shorted straight to a 24Volt control wire.

When the unit is in heat mode is the fan on the outside supose to run? Capacitor on outside and inside have been replace fan was running when capacitor was first replaced.


Hi, and the outdoor condenser fan should not be on at all in the heat mode unless this is a heat-pump!! So, I can see that this is a 3-ton Carrier split system and I haven't pulled up any information on it, only if I need to. But if the indoor unit runs on natural gas/propane, this would not be a heat-pump and the outdoor fan would run only in the cooling cycle. So, if it is not gas fired it is a heat-pump, and yes the outdoor unit should be up and running all year around. On a heat-pump you will have what is called a reversing valve in the refrigerant system that directs the flow of freon in the right direction for the season you are in. Most all heat-pumps will have a heat strip package installed in unit for emergency and aux. heat if compressor lets say fails. You're thermostat will have on it a selector switch, you will see on it these labels, Aux., emergency heat, auto/on/off/heat/cool. You will know from what I have just went through with you what you have. Forgive me for such a long explanation as I like my customers to understand more about there units in question. I could have just said yes or no and thanks? Doesn't work like that for me. I hope this has helped you out. One thing, If you determine this is a heat-pump and the fan is not on when in heat, you may have lost this condenser fan motor? You say both run caps. were replaced, and normally when you loose a run cap for a motor they will open internally, leak, buldge ect. So if this is taking place, if you can yourself take a look at the run cap. Also, make sure you have 220 volts to condensing unit. If not, check breaker probably a 30 amp double pole to see if it has tripped. You will have a disconnect box at the unit and inside there will also be 2 fuses. If you see only a pull out square connect, the fuses are still there but in behind the cover. If you have power and can hear the compressor come on but fan does not, I am positive you will have A faulty run cap, or faulty motor. Kill power to unit and try and slide a metal coat hanger down to prop or blade to see if it spins freely. If it is hard to turn bearings are froze up. If the capacitor seems to look ok, and the motor does spin free, It still may have open windings. Do these checks I have asked of you on power to the outdoor unit. If all is good, Stand in front of the unit and have someone turn the stat on for what season you are in. Lower or raise temp a ways above or below room temp. You should her the contactor close and compressor will start along with the condenser motor.If compressor starts and motor does not, then I would say it has failed and or cap again. When a motor is replaced, the run cap must always be replaced to!! Please get back to me and keep me posted. I will wait to hear what has happened. Good Luck.
Sincerely,
Shastalaker7

CARRIER MODEL 38YCA030370 MAKES HIGH PITCH ELECTRICAL HUMMING NOI


Yes it could be the pop off pressure relief on the compressor.
I assume it is the outdoor fan your referring to not running.

If this is a heat pump and it is in defrost (only in the heating mode should your outdoor fan be off and then for only a max of 12 to 15 minutes).
If it is just AC ir is Heat pump in cool mode, the out door fan should run while the compressor and indoor fan are on. Until the thermostat is satisfied on room temp.

This high pitched squealing is indicative of a bad fan motor or capacitor for the out door fan motor. Kill power and test blades to see if turns free. Check the run capacitor inside control panel. It is usually silver or aluminum colored (some are painted gray). The top should be flat with rolled edges and the sides should either be round or oval shaped with no swelling or oil leaking from inside it. If this all looks normal take it to where your going to get a motor any way and ask them to check it or sell you a replacement at the same time. These can go out usually from high voltage (lighting...) or from over heating (bad fan motor, dirty out door coil...).

Hope this helps you if not post back I'll respond as soon as I can. And please rate me as high as you can. Thank you for using Fix ya and good luck.
