Re: Haier heat pump 2yr old

I would start by checking or having the motor run capacitor read for it's value in microfarads.

Its always possible for a component like a relay to damage a motor. I normally see them run backwards due to a weak capacitor. A single phase motor is not supposed to run backwards but I've seen it many times. Ive seen a new motor run backwards, new capacitor, new air handler. To answer your question, its possible but likely it was the motor or relay.

How does it matter which direction condensor fan turns

Yes. The fan is designed to draw air through the condensing unit to expel heat generated by compression and heat exchange in the refrigeration system. If the fan is running the wrong way, heat will not be disipated correctly and the unit will not operate efficiently. You could end up damaging the system.

I have a Haier AP148DS portable ac unit. I had to replace the Condenser motor blower wheel and evaporator motor due to the old blower wheel broke. Now the evaporator motor won't turn on and I can't...

there is a start/run capacitor , did you check it to see if you have 115 vac ? also a contactor of 115 vac to check if contacts are dirty etc..

My goodman cental air system is having problems. First, the blower inside (furnace) keeps running for hrs after the outside condensor shuts down. Now, the condenser blower motor wont operate at full speed....

the cause of your indoor fan running all the time or for long time after your heat pump has stopped heating is the fan delay relay. It has welded its internal contacts together. If you take off the side below the control panel, the fan delay relay is normally mounted on the header where the fan discharges. Good news, the fan delay relay are fairly inexpensive and easily to change.

As far as the condensing fan motor not running at full speed, when it was changed, did the technician install the correct fan motor. Most condensing fan motors are either 875 rpm or 1175 rpm. They are exactly the same size and if the technician did not look closely he could have installed the wrong rpm motor. There is another possibility, he may have used the wrong capacitor. I have seen the condensing fan actually operate backwards at a lower than normal rpm. The fan if properly installed will discharge air upwards.

Central air conditoner outside unit

Well, the answer is yes. I have seen a bad capacitor cause a fan motor to run backwards. BUT..... After replacing the capacitor and WIRING it up the right way, everything should be fine. A lot of aftermarket condenser fan motors are reversible, so it can run counter-clockwise (CCW) or clock-wise (CW). However, most factory fan motors come one directional and on your specific unit, the air should always push out of the top. Running the unit with the fan going backwards will actually some-what do it's job, but damage other components like the compressor because it runs at higher operating pressures than what it is designed for.

Have someone else look at it! That's going to be the best advice I can give you. If they can prove that a capacitor caused the motor to permanently run backwards..... I want to know! Hope this helps and good luck with your unit.

Older Ruud heat pump. Fan on one side runs backwards. Most peculiar, Mama. Run cap maybe?

No the run cap will not do that...sometimes the wind can be blowing when the fan motor goes to start and then an older motor will continue to run the other then will remember that and keep on running wrong...
Bottom line is that you need to replace the motor...

You can get it running right usually if you shut it down... spin it the run way and then turn on the power, but often that will only work till it goes to start again...

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.

Amana Cooling Condensing Unit fan stops spinning after 15 mins

Capacitor, dirty condencer coil causing the motor amps to run too high. But most likely worn bearing on blade side of motor causing it to pull to one side causing it to over heat and shut down. Sleve bearings should have no side play.

Condenser fan running backwards on heat pump

I am having the same problem, sometimes it runs in the wrong direction, blowing the air down. Sometimes something gets tripped and I need to turn the thermostat to off and wait a bit then restart it. If I am lucky it will run int the correct direction and also will warm the house. Sometimes it send nothing but cold air to the house's forced air.
