Hello, My name is XXXXX XXXXX X will assist you today
There may be a simple solution.
Do you have the model of the new stat?
it isn't the thermostat, I reinstalled the old one and it still doesn't work
it is a goodman mid-effeciency furnance
If the blower runs, it shouldn't be the fuse
But there is a fuse on the furnace circuit board
what would you suggest to get some heat in here?
Can you tell me the wire colors and the terminal they go to on the stat?
there was a red, a green and a brown
Lets double check the wires at the stat first
you don't have air conditioning?
red went to r; green to G and the Browwn to Y
Y is for air conditioning
oh, so that is one problem
I will move it to the w
Brown is usually a neutral, but it must be used for heat in this case.
W is for heat
if I set it to w, the fan does not come on if the seeting is on heat, it will come on if it is on cold
The blower for the heat has a time delay at the furnace
Those are the only wires being used?
only 3 yes
i left it like that for some time so the delay shouldn't have been a problem
Put the brown back to the W and turn to heat, the burners should come on
okay, take the brown off and hold it to the red and see if the heat comes off
the fan comes on when it is turned on, but when I turn it to auto and turn up the heat it does not come on
I think the wire colors are not up to normal. The red may not be the hot
Is the furnace near by?
if i touch the green and red the fan comes on
the furnance is in the bsmt and I can go down there
Yes, but the green may be the hot wire
ok, what do you suggust I do?
go to the furnace and check what terminals have what color wire to them
We need to identify the hot
which is theR terminal
i'm at the furnace, how do i find it noiw?
do you see where the thermostat wires go into the furnace?
Just follow those wires and tell me what they connect to
I have a red and brown wire
the red goes to w r g c
the brow goes to r g
The red should go to the R
The green should go to the G
The brown should go to the W
the red = r
brown = w
while you are at the furnace, jumper from the R to the W and see if the heat comes on
on the furnace or thermostat
at the furnace
what do i use as a jumper?
is there a short piece of wire there? If not a paper clip unfolded will work
it is low voltage
don't know the volots
it should be 24 volts at those terminals, just like the stat
ok, the fan went on when i touched both the r and w
and the heat?
how do i tell if the heat is on
did you see if the burners came on at the furnace?
sorry, what do the burners look like
The section of the furnace you are looking at, is it where the blower is?
okay, burner did go on
lets go wire the stat to match the wires at the furnace now
red to R
green to G
brown to W
if I turned it to on, the fan does not go on on the heat but if I turn it to cold it goes on
doesn't go on on the auto function
you have the front on the stat?
We are connected as above? R G W ?
Why were you changing the thermostat?
to a programable one
I just to the face plate off and the fan turned on and now doesn't turn off
ok, so the heat was working before you changed it.
Is the fan to the on position?
now it is off
it wasn't on the on posisition
with fan on auto, turn the heat on and set above room temperature
then go down and see if the burners came on please
the burner is on and the fan is running
however, if I turn it to the off positioin, it doesn't turn off
looks like we got it
It will run on a timer and then shut off
turn it off and give it a couple minutes
i took the face plate off and it is still running
ok, I turned it off
the thermostat does not control the fan for heating
Now you can install the new stat using the same terminals we are using now.
you can check back if you have any problems
read the instructions good, you may need to set the new stat for gas heat.
Be sure you put all covers back on the furnace.
Thank you again,
