Nest E not firing bolier

[kena1921]

Hi

We have just moved into a house with an existing Nest E system.

I've manged to set the system up, put it on wi-fi and connect it to the app.  Everything seems to be working fine but I can't get the boiler to fire.

At present the app is showing that the temperature is 17.  I have set the desired temperature to 20 and the app tells me that it will reach this in 35 minutes.  However the boiler refuses to fire and nothing happens.  We are having no problem with hot water.

Any help with this will be gratefully received as its getting colder here!

Hi kena1921, 

Yikes! I'm sorry to hear that your boiler refuses to fire and nothing happens. Let me take a look at this for you. A few questions: 

• Are you located in North America or Europe?
• What type of Nest Thermostat do you have?
• Does the thermostat screen indicate that it’s actively calling for heating?
• What type of furnace do you have? (gas, electric, etc.)
• When did heating last work?
• Did heating ever work with the Nest Thermostat? If not, did the heating work with the previous thermostat?
• Did you turn off the power to the HVAC system?
  • Did you recently turn off any breakers?
  • Have you recently experienced a brownout or blackout?
  • Is there a light switch near the heater that controls an outlet?
• Did you select the correct fuel type?
• Do the LED lights blink on the HVAC control board? If yes, locate the light.
• When was the last time you changed the furnace's air filter?
• Have you experienced extremely cold weather lately?
• Is this the first notable temperature drop of the year in the area?

I'll look forward to your response. 

Best,

Zoe
