    check your circuit breakers in your house panel labeled heatpump or outdoor unit or a/c be sure they are on and not tripped

    you have a box near the outdoor unit that may or will contain a breaker or fuses you need to be sure it is on and if fuses you need to be sure they are good with a continuity tester after you remove them

    turn electric off before you remove them if you have fuses or see what they are and replace both if u have no tester.

    check for any external reset switches ,buttons etc

My Goodman heat pump doesn't blow air through the vents into the house, but the fan comes on when the thermostat is turn on for the air conditioning


Check first that
  • the air conditioning equipment is turned on,
  • the thermostat is calling for cooling, and that
  • the blower unit or air handler is actually blowing air through the ductwork.
Here are the details of what to check in what order if your air condtioner or heat pump doesn't start at all when you set the room thermostat to call for cooling:
  1. Check the Room Thermostat Temperature Setting: Set the thermostat to at least 5 degrees below room temperature. Our elderly mom has no patience with switches and controls. She regularly calls her air conditioning service company with a service request, sometimes late at night, because she has simply failed to set the temperature on the thermostat lower than the room temperature. Don't drive your A/C like our mother.
  2. Check that the Room Thermostat is set to "Cool" not "Off" or "Heat". If the thermostat is not set to "cool" it is simply turning off your A/C. If the thermostat display is blank then it's not receiving power (for modern digital thermostats). Check that electrical power is on at the air handler and to the the low-voltage transformer that supplies power to the thermostat.

    If the thermostat has power, check that when you set the thermostat temperature down at least 5 degrees below room temperature the thermostat calls for cooling. If it doesn't then check for broken or shorted thermostat wires anywhere between the wall thermostat and the control board at the air handler.

    You can easily eliminate possible thermostat problems as a cause of failure of the air conditioner to start by simply eliminating the thermostat from the picture: disconnect the thermostat wires at the blower unit's control board and instead connect the two thermostat terminals directly together with a jumper wire. If the system starts then the problem is in the thermostat itself or in its wiring.

    If the thermostat is working but the compressor condenser unit won't start, you could skip ahead
    to COMPRESSOR / CONDENSER DIAGNOSTICS but I wish you'd double check the remaining steps in this article first because there are some sneaky snafus listed below that might still be the problem.

  3. Check that electricity is on for the equipment. Check all of the electrical switches and controls that can turn electrical power off at the indoor air handler or at the outdoor compressor/condenser unit. There are more of these switches than you might guess. Here's a list of what to check:

    Electrical power switches and service switches outside by the compressor, inside at the air handler, and fuses or circuit breakers in the electrical panel. Don't forget to check that the access covers to the equipment are properly closed and latched. Otherwise a
    BLOWER DOOR SAFETY SWITCH could be keeping the equipment from running.

    There are several other safety switches and controls, both manual and automatic that can leave an air conditioner or heat pump turned "off" such as a blower compartment door interlock safety switch, an electric motor overload or overheat switches, and a condensate tray spillage detector switch.

    Some hard-to-find electrical switches on an air conditioner or heat pump could be keeping your air conditioner from starting, such as
    a FLOAT SWITCH on Condensate Tray that could
    be
    causing CONDENSATE PAN SWITCH LOCKOUT - condensate spilling into an overflow pan that uses a sensor switch can be enough to shut down your air conditioner.
    or
    a blower MOTOR OVERLOAD RESET SWITCH could be keeping a fan motor from starting.

    A bad or failed starter capacitor could also be leaving your system shut down, failing to start a blower, fan, or compressor motor.
    See CAPACITORS for HARD STARTING MOTORS

    Watch out: See A/C - HEAT PUMP CONTROLS & SWITCHES to be sure you have found and checked everymanual or automatic electrical switch on the system.
  4. Check the electrical supply voltage. Even if electricity is on, if the supply voltage has fallen too far below the operating voltage range of your air conditioner it's likely that the system will not operate, particlarly, you may note that the compressor motor won't start.

I was leaning towards a bad contactor. Either sticking sometimes or not making good contact. I would inspect the contactor for pits or burn marks near the contacts.

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,

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.

Dometic ac/heat pump


Would suggest it is drawing excessive current, make sure both fans are going, (inside will cycle low/high), or possible faulty reversing valve solenoid, or could be as simple as loose wire connection, how long does it run for and is it on the same 20amp breaker as the rear?if so start by running only the front unit in cooling 15/20min, check fans running, no unusual bearing noises, switch off for 60 sec then back on heat mode, if unit runs without stopping rewire onto separate circuit, if inside fan not working on heat check bi-metal switch in the airway, if running for a while, fans going but not very warm, check reversing valve.
Note, electrical's should be tested by someone who are qualified in the field.

High Pressure cutoff


YOUR OUTDOOR FAN MOTOR SHOULD NEVER SHUT OFF IN THE AC MODE. IT IS SUPPOSED TO SHUT OFF IN THE HEAT MODE WHEN ITS IN DEFROST. IF THE UNIT IS RUNNING IN COOL AND THE OUTSIDE MOTOR QUITS ,THE COMPRESSOR WILL QUIT SOON AFTER. EITHER THE RUN CAPACITOR FOR THE FAN IS BAD OR THE FAN MOTOR ITSELF IS BAD, IF CAP IS GOOD THEN THE MOTOR IS At FAULT. THE OUTDOOR PRESSURE SWITCH CAN ALSO OPEN IF THE INDOOR FAN MOTOR FAILS IN HEAT OR THE FILTER IS PLUM NASTY in heat OR THE INDOOR COIL IS PLUGGED UP in heat.. THE PRESSURE SWITCH USUALLY TRIPS AT 400 TO 425 SO ITS WORKING CORRECTLY. YOU MAY BE CONFUSING THE ISSUE SAYING THAT THE AIR IS HOT AND COLD INSIDE. IT IS COLD WHEN AC IS RUNNING HOT WHEN HEAT PUMP IS RUNNING IN HEAT BUT ESSENTIALLY not cold or hot if compressor isn't running, but a lot of folks describe the lack of cold air as hot when the compressor isnt running. but it basically is warm or house air temp.you test the capacitor with a capacitor tester or take it to motor shop and let them test it. odds are its a 5 , 7.5 or a 10. it should test within 10 % of rated value . ask for a RESCUE brand replacement motor. they are great ,reversable etc.carefully oil and sand the motor shaft and note exactly where the blade was located in relation to the grill so you get it back just the same. usually they wire up black to a leg of 220 power. white to the other leg of 220 power. brown and brown with white stripe to the capacitor.you can also pull whole fan shroud assembly on some units and take whole thing to motor shop and let them test motor cap, replace and all you do is return to unit and connect two power leads,
