SOURCE: Replaced thermostat on FA4ANF030 with Honeywell model rth3100c does not work

If you have a heat pump do not put your blue wire on b. Put it on x or c. If you don't have an inline fuse you may have blown your transformer.

SOURCE: Air handler motor and capacitor

Just take out the fan and capacitor they are not OEM so any fan motor would work as long as same Horsepower and milti speed. And the capacitor is a 5 uf or maybe 7.5. You might have to cut off the shaft of the new fan motor so it don't stick out.. You can get a new fan and capacitor at any Heating and Air parts house. And you are sure they are bad you ohmed them out? Fans are not cheap about 50-75 bucks retail. Let me know how it goes. ken

SOURCE: Goodman Air Handler motor will not turn off.

Look at your Thermostat wiring.
If there is a green wire going to the "G" terminal, disconnect it.

If it stops running, you have a bad T-stat.

If it keeps running, you either have a stuck fan relay or a low voltage control wiring malfunction.
Those are usually related to one of the safety switches having problems.

If green is not going to G, let me know, and we will determine which one is indeed the fan wire and go from there.

SOURCE: My air handler comes on ,not the outside unit when

If you have a standard thermostat the fan switch is for the air handler only. It completely over rides the thermostat for most settings. Now lets see this is what I'd expect:
fan switch on Indoor fan runs all time
Fan switch auto Indoor fan only runs when thermostat is set to cool or heat and the thermostat is turned up above room temp for heat or below room temp for cooling. In both of these modes the furnace blower comes on and stays on til the room temperature is satisfied. The outdoor unit only comes on for AC the out door unit will not come on for heat or the "on" setting on the thermostat. See exception 1 & 2 below...

Exception 1- (in a heat pump the out door unit runs in both heat and cool mode unless it has emergency heat turned on then it will not come on outside in the heat mode, and depending on the type of heat pump and furnace or air handler it is). A heat pump thermostat usually has "backup heat" and an "emergency heat" setting switch on the thermostat.
Exception 2 - On some thermostats they are made to cycle on the heat if the temperature reaches a preset temp (around 50'f usually but definitely by 40'f). This mode prevents freezing when if instance the homeowner is away or while the home is under construction. In this mode the fan inside can run but the heat usually comes on with it.
Exception3 - On some electric furnaces the heating strips may be individually controlled and thus not all come on at one time. This may give the feel of no heat especially if the room is cold.

Now there may be other exceptions but Ive tried to give you a heads up on some of the most common ones.
If you need more help please post more specifics about your unit/system as to for sure what switches are set to what setting and what is happening with each. My first though was that maybe your system is OK and you needed to know if the thermostat was working properly.

If this helpd you understand your problem would you please give me as hifgh a mark as you can. Thnaks for using fixya and good luck.

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.
    See VOLTS MEASUREMENT METHODS

Goodman package heatpump blower motor contant running


check your themostat fan mode switch to see if it in on or auto. It should be in auto. If this does not stop indoor fan motor, (it may take up to 2 minutes for the fan to stop, preprogrammed shutoff in the thermostat and fan control cards may make you think the fan has not stopped ) If this does not stop the fan the fan control board in your air handler has a green wire shorting to 24 volt signal in the theromostat wire or the contact on the blower control card is stuck and will need replaced.

Communication problem. You say condenser stat and power are fine? if that means the condenser runs but the air handler doesn't that means the communication is good and the blower is not running. That may be a capacitor (you must have ammeter capable of checking microfarads) if not that check power it may be board driven. If no power to blower the board is bad assuming power is at board. If that is ok the blower motor is bad.

Indoor blower not running,capacitor is good,blower motor is good


have you check the 24 volt transformer in the air handler? you must have 24 volts from the thermostat to the tranformer in the air handler.

My 5 ton Goodman Heat Pump won't go into heat or ac mode. Fan won't turn on. No noise from compressor. System is 1 1/2 yeras old.


Easy: Turn the "fan" switch to on at the thermostat and see if the blower starts. If no start, check breaker at breaker box. Check service disconnect at or near the air handler. With the breaker and/or service disconnect OFF check the 3 or 5 amp fuse inside the top cover in the air handler.
Not so easy: (You must know what you are doing for this part or let an HVAC Tech do it for you) Open thermostat and firmly jump the Y and R terminals to see if you get the compressor to start for no more than 30 seconds. (don't do it more than once.) Jump the G and R terminals to see if you get the blower to start. If so, u have a bad thermostat. If not, check the transformer inside the same cover in air handler for proper voltage. (24V. Make sure you also get 220 on the opposite side of the transformer)
If the blower comes on, but the heat pump doesnt start, open the side cover of the heat pump, with the thermostat on cool, and the temp. setting as low as possible for at least 10 minutes see if the contactor is pulled in. If so, check the capacitor and see if it's blown out. Be super careful these systems operate with 220v and the amperes are enough to kill you if you make a simple mistake.

Split straight air system with outside unit comes on and air handler does not whether on auto or on position with temp down or up


Either the thermostat, fan relay on circut board or blower motor bad. Jumper the R and G terminals together on the circut board, depress the door switch and see if the blower runs, if not, check for power to motor, capacitor and motor windings. If it runs then you have tstat/control voltage wiring problem.
