Anyhow, hope you figure it out. Let me know how it goes. For a second stage cooling you need need a Y-2 terminal in the thermostat and it needs to be properly connected in the air handler and condenser. If you have a two-stage furnace with a two stage air conditioner then you need extra wires for that as described in the article above for staging plus you need a common wire. Lastly, the outside air temperature sensor needs to have two wires terminated at S1 and S2 and are dedicated directly to a thermistor located outside somewhere. I add write up how each is connected if that helps. Simply add a wire under the C terminal in the air handler.

This type of wire is different from the typical thermostat wire and a separate wire altogether. I can go into more specifics if needed. Thank you, for your cooperation. And to really find out the mysterious black wire you have to trace it to the air handler but be very careful because it contains high voltage and really should only be looked at by someone who has training and knows what they are looking at.

The most common cause is either a bad transformer, bad hot surface ignitor or pressure switch failure. So, theoretically, the additional wires should make the unit functional, just maybe at a cost of variable fan speed control from the thermostat. W2 β€” This is the terminal used for second stage heat. Listed below is a great photo for ruud gas furnace wiring. Roll out is a safety feature that is used in the heating cycle.

It almost sounds like when you take the cover off, you are pulling enough air into the system for it to run, but as soon as you close it off, it's not getting enough air flow, therefore, tripping a limit switch inside the furnace. No one knows until its gone through troubleshooting. Most furnaces will also have the codes for the flashing lights and what they mean on the inside of the door covers. On a split system the blower fan is in the air handler. The board will flash a trouble code.

A package unit the blower fan is in the outdoor package unit. Thanks in advance for your input. All of it is free. This can get complex especially when the word algorithm is used but the control is much more precise when it is done properly and in the long run that will save you money. It is likely you have a simple R terminal at the thermostat and that is where the red wire should be terminated.

I travel a lot and can turn things on and off from afar. Let the furnace cycle and see if it flashes a code. However, can the heat pump operate normally if the fan wire is not connected? If that is not possible then trace the wire out to the source. If your in the trade, get your post count up to 15, and apply for Pro Membership. Should the humidifier be attached to the green terminal? Attach that wire to the C terminal at both the new thermostat and the control board.

I took a look at the furnace and at the board, the guy never installed the two wires coming from the Contactor low Volt Side. Where you can ask and get answers to technical questions. My current thermostat only has 4 wires power, common, 1, and 2 with 1 being cool or heat and 2 being the other I think. Someone who knows what they are doing needs to confirm the wiring colors at the other end where they are terminated in the air handler and the condenser. It is simply a spare wire in the bundle.
