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.

Ok, you either have a inducer fan issue or a pressure switch issue or a plugged vent pipe. The inducer turns on to establish a draft for the exhaust. If it is not working you will get this error code. If the pressure switch does not sense pressure caused by the inducer, it will give this code. If either the intake pipe or exhaust pipe is blocked (even y just a little) it will give you the same error code. If the condensate hose or receptical is plugged, again it will give you this error code. Good Luck!

SOURCE: MY HEAT PUMP SYSTEM WILL NOT WORK IN EMERGENCY MODE

the thermostat sub base has a place to connect a wire usually white to energize the heat strips when you push the stat way hotter than the house temp. that is why the strips come on in normal heat. it also has a terminal that is only energized in emergency heat and it also should have a wire connected to it so that terminal can supply power to the strips when the stat is switched into emerg heat . you can identify the terminal from the wiring diagram and if need be jumper w2 wire over to the aux terminal and it will work. they both go back into the airhandler and power the same strips. w2..................................................................................................w2 in airhandler to strips or w2...jumper to aux......................................................................................................................w2 in airhandler to strips.

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

My Goodman ARUF182416 does not stop running. I have disconnected the thermostat and the blower and heat element stay running until turning off via circuit breaker.


From what I can gather it seems like a power source error (red wires attached to the transformer) is allowing it to keep running. Another possibility is it could be your speed tap. These are my speculations about what is occurring.

Need to know how a mobile home split system is wired with just ac and 15 kW heat stripesqqq


you have to have 240 volts for power. 24 volts to operate cool and heat. thermostat feeds color code white to heat yellow to cool green to fan. think of the thermostat as a light switch. transformer in system feeds common to different controls & usually red to thermostat which is then switched to what it is set for.

To me it sounds like you need a fan limit switch to sense temperature increase and turn your fan on. At least you know that everything else is working. With out a schematic I can not tell you what type of limit this would be but I would look for a sensor either mounted right above the coils or beside them.
Have you looked on the inside of cover plate for heating and blower compartments.Often times they will put a wiring diagram there. Wished I could be of more help. Thank you

High low fan motor


Your main concern is the temperature difference across the indoor coil for both heating and cooling. When you turn your thermostat from auto to on, you are on high speed.

If you have long duct runs and little return air registers then high speed
would help cool the house better. However in the heating mode, you
could lose up to 10degrees by having the high speed setting.

What they installed is sized for your house and the speeds should not have to be changed unless the ductwork is not sized right for the house.
Cooling should be High-Black wire.
Heating should be Low-Red Wire.

400cfm equals a ton of cooling= 1200 sq. foot, For cooling you need
High speed. For heating it is whatever the temperature rise across the
coil is, which is located on the furnace/air handler.

Disconnect all wires to start.
1)Go out to unit shut off power and remove electircal panel.

2) Locate the terminal board where thermostat wires are connected. Write down where each color goes to
each letter and then try to do this at the thermostat.

R= Red wire= Power
G= Green Wire= Fan Leg
W or W1= White Wire= Heat Leg
Y1 or Y2= Blue or Yellow Wire= Cool Leg
C=Brown or Black or Orange= Common if used

Furnace will not shut off after the setting is reached. have changed thermostat. Temperature reading goes down on thermostat, furnace still runs. Model : Goodman furnace,gmh95/gch9


Check if your thermostat is set on 'o fan' setting.
If it is, trey to set it on 'Auto-fan' instead.
since it seem as if the heating does go off,only the fan may be running continuously.
this is possible if the thermostat is incorrectly set or installed.
good luck.

What's the deal? Wont shut off or respond to thermostat. . .


Red= power........White=heat.............Green=fan.................(grey)-(yellow)=cool .....these are the connectons. Disconnect these wires from the thermostat and know that red/power is the only wire that send power to the thermostat, and the rest sends it back to the unit to call for whatever,, red--to . white for heat... red to green for fan .... &red to grey for cool! OK! Turn all your power on, and use a jumper wire from red / green for fan and see if the fan comes on! Then move the jumper wire from red to green , to red / to white for heat and the fan , wait for 3 minutes before removing and going to the next step. Then red /to grey for cool and check if the outside comes on. Either you have a wire touching past the insulations and making a connection, a bad thermostat ,oe excessive wire lead touching the next connection.Thank you very much!

A/C won't turn off regardless of thermostat setting ? GMP075-3 w/ 2 ton A/C


If you are able to shut the system down by using the thermostat as mentioned, the thermostat is either bad or the programming is messed up. Check the fan switch and turn it to "Auto".
