I have a g61 movie. I am trying to install a Honeywell Wi Fi

Customer Question

I have a g61 movie. I am trying to install a Honeywell Wi Fi thermostat. There does not seem to be an empty spot on the furnace for the common wire (c). Is there anything I can do. The c spot on there is going out to the air conditioner.

Your C from thermostat is going to go into the C terminal along with the Common from outdoor unit

It's ok to put 2 wires onto the same terminal?
Customer: replied 8 months ago.
I don't have the C installed yet so I switched the c to the g on the thermostat and put the g into the c at the furnace. I turned the power back on and I there is no power to the thermostat.

OK did you turn power off before starting? If not look on control board to see if the little 3 amp fuse is blown.

If you are using the G wire as a work around to keep from adding a wire, It will need to move from G to C bot at thermostat and at furnace board.Yes it is ok to have 2 wires at the C terminal on board.One from thermostat and one to outdoor unit.

I see the fuse it says 3 amp on it. How do you tell if it's blown. How do you pull it out? I think I did turn the power out. But I turned it back on.
Expert:  airheatman replied 8 months ago.

If you turned it on with C connected to G you probably blew fuse. Use a pair of needle nose pliers to grasp it and pull it out to look to see if it is burned

Customer: replied 8 months ago.
I have not attached the connector yet from the g to the y( I think it isn't) would that effect anything?
Expert:  airheatman replied 8 months ago.

Lets check fuse first and then we will go this step by step

Customer: replied 8 months ago.
I think I just broke the fuse. I broke a plastic piece off the front. Is the fuse in the back?
Expert:  airheatman replied 8 months ago.

WEre you able to get the fuse off of the board?

Customer: replied 8 months ago.
I broke a plastic piece off the front. Maybe the fuse went flying.
Expert:  airheatman replied 8 months ago.

OK lets get another fuse first. Then before turning anything on, wire as follows

Furnace ------------------Thermostat

R-------------------------------R/RC

W--------------------------------W

Y---------------------------------Y

C---------------------------------C

Then at furnace run a jumper from Y to G (This will energize blower along with ac on call for cool.

Expert:  airheatman replied 8 months ago.
