Nest 3rd gen furnace heat won’t come on

Kennystewart80 — Fri, 30 Sep 2022 05:36:49 GMT

Hey, My furnace comes on but won’t ignite a flame, so just blows cold air. Hooked up my old thermostat again and it worked just fine. Any thoughts from anyone ?

You Nest might not configured properly for your heating system. Your heating is initialized by the thermostat connecting R to W. Your seems to be connecting to R to G and not including W. Please check your nest equipment configuration. Heating FUEL TYPE should be GAS, and HEATING TYPE should be FORCED AIR. Make shire the wire in W is properly installed.

Hi there,

@CoolingWizard, thanks for assisting.

@Kennystewart80, I'm sorry to hear about the issue you're having with your Nest Thermostat that won't activate the heat. A few things to isolate:

What type of HVAC system do you have?
When did heating last work?
Does the thermostat screen indicate that it’s actively calling for heating?

Looking forward to your response.

Regards,

Mark
