Electrical Question from Diane
[ad#block]Electrical Question: I put in a new thermostat. The old one was removed without labeling the wires. A furnace and air conditioner are both run on it. Thermostat wires consist of blue, white, red and green. Furnace wires are White in white, blue in yellow, green in green Red in Red. Air conditioner consist of two wires. Red wire is with blue wire from furnace in yellow spot. White wire is in a “c” spot. There is a RC spot on thermostat that has a jumper wire to the red spot. Any suggestions. On the thermostat I have the blue wire in the blue spot and the white with white spot and green with green and red with red. The air only works when in the heat mode of the thermostat. If you need pictures I can try to get them tomorrow.
