Have HVAC Questions? Ask an HVAC Expert for Answers
Do you have certain wires you have a question on?
that is a computer generated offer...not from me..I cannot call anyway.
If you want help with the wiring let me know or I will just send to customer service to cancel
And do you have a heat pump?
red to R
yellow to Y
white to aux
orange to O (unless outdoor is Rheem/Ruud product..if so then orange to B)
green to g
blue to c
What brand is outdoor?
also you need a short wire to connect E terminal to Aux terminal
ok this changes things..
they could have used the blue for B...or the orange for B.
Can you open the air handler?
The jumper gets missed alot.
If the O/B is an issue let me know. Rheem and Ruud are the only ones who use B as a reverse valve instead of O.
That is why it is best to open the air handler and see where it goes.
Usually on a Rheem/Ruud the orange is not used....or it is on B....the blue is usually C...but then that Rheem Ruud issue pops up and some techs use blue.
Can you see where the blue or orange attach in the air handler?
do you know where the filter gets changed?
can you tell me the model number of the outdoor unit and I will check
thank you....leaving that unit are pipes...the pipes lead to a blower unit inside the home...could be attic, closet or basement
the wires from the thermostat go up to the blower unit in attic. The same wires you see at thermostat then attach to terminals inside the blower. WE just need to see where the orange or blue go.
Do you remember if both attached to old thermostat?
Many times there are extras not used.
Then wire as mentioned...
but red to r
yellow to y
orange to B
blue to C
green to G
jumper from E to aux
you are very welcome and thank you for the patience
Side note...make sure power is off to the air handler when changing the wires..
I am sorry, I thought we were through. The power must be turned off at electrical panel or the air handler.
take the red wire and the green wire at thermostat and hold direct together...does the main blower kick on?
ok then if the wires were removed from old thermostat while air handler was not turned off it blew a fuse. If we get the model number of the air handler I can direct with pictures
if you cannot find a number you can post pics of the unit with door off
ok this will depend on the age of the unit if there is a fuse...the fuse I refer to is the the main breaker or fuses..it is a small 24v fuse just for the thermostat wiring.
Looks like we need to open the front....do you know what the transformer is ?
I wish you the best...just rate service to move off active list
