Wiring my Criterion Gass Furnace to a nest. I only have a

Customer Question

Customer: Wiring my Criterion Gass Furnace to a nest. I only have a red yellow ( which acts as a white) and green wire. If I put the red in the R spot on the nest one it goes from the starting to sire up to the burn stage it shuts down. When I put it in the red in the RC spot it doesn't even go to the start the burn stage. We had our furnace worked on and they had to put a new control panel in and now our nest doesn't seem to work.
JA: Thanks. Can you give me any more details about your issue?
Customer: We had the furnace fixed because it would keep shutting down right before it would start the burners. the Tech replace the pressure valve, then they came and tried a regular old thermostat and to day the replace the control panel. I can't get the nest to work with the control panel on the furnace.
JA: OK got it. Last thing — JustAnswer charges a fee (generally around $18) to post your type of question to HVAC Experts (you only pay if satisfied). There are a couple customers ahead of you. Are you willing to wait a bit?

Usually R and RC would be connected together and then the red wire put on either of these two. The Nest usually requires a C or common so you may need to use the green as a common and put it on C at the Nest and transfer the green wire at the furnace to C as well.
