My name is ***** *****. I have a Rodgers Model# 1F78

Customer Question

Customer: My name is ***** *****. I have a White Rodgers Model# ***** thermostat which I am replacing with a Nest 3rd generation thermostat. The Nest thermostat is supposed to be testing the heating, but nothing is happening, so I'm wondering if my wiring is wrong.
JA: Thanks. Can you give me any more details about your issue?
Customer: The wires on the White Rodgers thermostat were connected as follows: - White wire to W, red to RC, yellow to Y, green to G. I've connected them to the Nest as: white to W1, yellow to Y1, red to RC, and Green to G. I have a Honeywell gas forced air furnace (house a year old, so all pretty new). The Nest seemed to set up fine, recognized the wires as I'd set them up, but the furnace isn't kicking in.
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?
Customer: I don't mind paying if I get a positive result
JA: OK. Now I'm going to take you to a page to place a secure deposit with JustAnswer. Don't worry, this chat is saved. After that, we will finish helping you.

I'm going to open this backup to my colleagues so one of them can help. Please don't respond (even to acknowledge this post)until you get a response from us. If you respond first it will only delay your answer.

Lets start by moving the R wire over to RH instead of RC and see if this makes a difference.
