Check your filter if u havent, most heat units have some sort of safety interlock should inlet air flow be restricted or blocked. If not could be ignition components or board issues. Over 8 major items will cause "No Heat" issues if it malfunctions, a few costly, so you'll want to be through tracing out your circuits & safety loops.. Or Call a Pro......

    If filter was found very dirty/clogged then chances are one or more safetys tripped . Change filter & reset. The safety interlock switches are located in the burner compartment. They are "Dime sized" round black plastic or porcelin bodied with 2 wires going to each. They have a red or black stem in center between the 2 wire terminals which is a manual reset button. Turn off power switch & a pen (non-metal) to push stem inward. If a click is heard, it was tripped & now reset. These safetys can be found in several locations & there will be 2 to 4 of them; Usually above center & center front of burner tube chamber, on top of air blower shroud(case) or right above it near inlet; and sometimes one near exaust outlet/draft blower assy.

    After checking safetys, see if there is a red glow or a clicking & arcing from the ignitor glow bar or spark probe, if SO then there is a gas flow issue ( gas valve or control board) if NO look for air draft inducer assy, then pressure switch, or also control board malfunction.

SOURCE: goodman split unit that heats instead of cools

Hi, Could be a run capacitor on the fan motor. They usually swell up and or leak when they go bad. If not, the only real way to test them it with a specific capacitor tester. A new capacitor would be cheaper. Make sure that the outside unit is disconnected from power before opening it up, try to spin the fan blade by hand. If it doesn't spin freely it may need oiled if possible. See above solution. Your problem is the fan motor though so if this don't do it, It will have to be replaced. If this helps, Please rate my solution. Thanks, kstfas

Goodman energizes it reversing valve in the cooling mode. Usually in the "o" circuit of the thermostat wiring.You may have that wired hot somehow.

SOURCE: My blower motor doesn't blow air out the air ducts why

Check for a frozen cooling coil. Turn the fan to the on position at the thermostat and the cooling to off. Your cooling coil may be iced over. Allow it to run in the fan only mode until the coil has had a chance to defrost. At the outside unit you may see the large line is frosted. This is the visual indication for a frozen coil. When you return the A/C to cooling use it with the fan on while in the cooling mode.

Assumed all the wiring are correct,

to change from manual switching from heat to cool, press [system] button ( left ) to go into system setting.

then press and hold the [fan] middle button untill option display 120

use up down button to select option 300 ( Manual/Autochangeover) ,

select 0 for manual, 1 for automatic. ( read caution in page 22 of installation manual )

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

Its possible but you might try a little diagnostics first. Put your thermostat in the off position and the fan switch in the auto position. Make sure the switch on the air handler inside is on. Now have someone stand by the blower while you switch the fan switch back and forth from auto to on. If the person at the blower hears a clicking sound from inside the blower cabinet you probably have a bad motor. But if you hear nothing it probably means you don't have power. Check the blower door to make sure its tight and the safety switch is depressed. The wall switch should be tested. Don't have any easy ways to check for power without a volt meter. Hope this helps good luck.

Furnace switches to auxiliary heat while in cool


It's likely a bad tstat. Turn the power off to your air handler. Remove red , green, yellow and orange wires inside the tstat and wire nut them together. Not sure if your reversing valve energizes in heating or cooling but, turn the power back on. If the unit is heating turn the power off and remove just the orange wire and turn power back on. Let this run and see if it you are ONLY getting cool air ALL the time. If so you have a bad stat. If still getting heat possibly you have a bad control board in the air handler. Good Luck!!

If you changed the unit but didn't change the thermostat it is possible that the thermostat that you have will not work with that unit. I see that the unit you installed is a heat pump, you may have a straight cool T-Stat. If you put the T-Stat in the "Auto" "Heat" mode the outdoor fan and the compressor should be workng as well as the blower fan. If it turns out that the outdoor fan and compressor are not running you will want to buy a Thernostat that is compatable with heatpumps should be 2 heat/ 1 cool

Hello,Next is make sure the thermostat is set for ELECTRIC heat.In the back there is a dip switch or sometimes a small jumper that MUST be set to ELECTRIC setting.It will give a choice GAS/ELEC it needs to be set ELEC to bring on the BLOWER on a call for heat.It doese'nt matter if you have gas or oil or wood for fuel.

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.

Goodman PHJK048 Heat Pump Package


ok...where to start.lol ....the thermostat is just a switch.It will tell the unit to run or not run.if you measure the temp with the heatpump running,the air is warmer than 68 but it feels cool to you because your body is 98.6.The unit will run more often and for longer periods when the temperature drops outside for a few reasons.First,your house has more of a load to heat,meaning you have more heat loss because of the difference in temperatures outside and inside.Second,your heat pump pulls heat from the outside air.The colder the air outside,the less btu's for it to pull.If you have anymore questions hillbuck29@aol.com Hope this helps,Dave

I just had a new unit installed and I am surfing for troubleshooting tips too. My unit is doing the same... cools well heat sucks. my problem has been isolated down to the reversing valve... It is constantly energised which means it is constantly in a/c mode even when kicking on the heat strips... We disconnected a line at the thermostat and it is working well as a heater now. You may want to check yours to see if it is actually kicking over into to heat mode... -rob
