I am having issues with a honeywell thermostat i just bought and installed
what type of furnace do you have? with a/c or heat pump?
i dont know brand it is a gas heater
how many wires was there to put on the new thermostat?
Im wondering if you maybe blew a small fuse in the furnace
is it a normal furnace
there are 5 wires and im gonna go up and look at the furnace now
ok, when you do, find the main power switch to the furnace, shut it off
then fine where the thermostat wire goes into the furnace, it will connect to a computer board of some sort, on that board there will probably be a blade type fuse, 5 or 3 amp
looks like a automotive type
that is a link to a picture of the fuse
comfortmaker is the type. it is in the attic
found the computer board...now what?
ok try and have a look for the fuse
i put a link there above , that is likely what you are looking for
is the fuse going to be behind the panel with all the wires?
found it..now what?
there's a number "5" on the fuse and and it's plugged in to a terminal labeled F1 if that means anything
yep that would be the one
remove it (power is off right?) and have a look
if it is blown, the little metal strip that connect the 2 sides will be broken
yes, power is off, and the two little pieces of metal in the middle that are shaped like a "z" are not connected. is that what we are looking for?
yes thats right
the z should be solid from one end to the other
oh, good to know. so, does that mean we just have to repace this and we should be good to go?
and where would we find this piece? home depot?
or radio shack?
more than likely yes, the fuse is there to protect the rest of the circuitry so it will likely be fine with a new fuse
either one, but i would try radio shack first
automotive supply store also would be a good place to try
once we get the new part, should we reinstall the new thermostat?
or just put the power back on?
sure if that was your plan in the beginning
but if you ever have to mess with the thermostat wires again, or any wires for that matter, just turn off the furnace power first, that way the fuse will not blow
i would leave the old stat on for now, put the new fuse in and make sure everything works. then shut power off and put the new stat on, power on and you should be good (the new stat may need to be programmed to your preference)
great! thanks for your help. So, basically we just blew a fuse and thats why it won't work?
Appreciate the help
That is the low voltage circuitry fuse, so since the power was still on when you were changing the stat, the wires touched each other and caused a short, so the fuse just pops
Youre welcome, if for some reason that doesnt get you going you can come and carry on the conversation later
well, thanks again!
so, quick question...first time using this....do I wait to see if this works and then "accept" or do it now and if it doesn't can i still come back in the chat?
I believe you can come back even if you accept now, but you can wait if you like, up to you..
replaced the fuse, and it still won't work
sorry i didnt get this till now
are you using the old thermostat?
we tried but can't get the wires to connect where they are suposed to.
we had already put in the new one before we knew it didn't work
does anything work, like the fan on button?
tried that. we switch heat on, nothing
put fan on, nothing. even tried a/c...nothing
there is 5 wires right?
before we get too far, maybe check the fuse again
upstairs connected to the furnace, its a
red to r
white to w
yellow and another red going to y
green going to g
another white and copper going to c
yet by the panel we have 5 wires
and the fuse is still good
2 of those wires will be going to the outside a/c unit
what do we have for wires at the stat?
do you have the door back on the furnace while you were trying it? (there is a door cutoff switch on the furnace)
a "c" wire that the instructions on the new thermostat say not to use; blue, yellow, green, red, and copper. pld thermostat had copper plugged into c and blue was tucked into wall
no we didn't. we will try that now
should we plug in the blue wire even though it wasn't plugged in before?
no leave the blue unhooked
and leave the copper unhooked from c for now too
we don't have a "c" on the new thermostat
that makes that easy then lol
do you have a white wire for W by the therm? i imagine you do, you just didnt list it
ok, so with the door on the furnace what is happening
and the power on
putting the door back on now
then going to flip the power
woohooo! it's on!
are we ever going to have to plug in the blue?
or are we good for heat and a/c?
no you wont need the blue, its not hooked up at the other end
yep with the 4 wires you should be good
the c wire is for 24 volt power for the thermostat (instead of running on batteries) but i guess your stat just doesnt bother with it
ahhhh....that makes sense
thanks a bunch!
have a good night!
