    Did you see a orange glow after you shut it off and turn it back on you should see a orange glow and then after a minute to 90 seconds you should hear a click that's the firing valve

    The furnace should have a power indicator light. If it isn't on, you may have blown the control voltage fuse. If it is on, it should be blinking a trouble code if the furnace isn't working. To find the fuse or know how to respond to the trouble code, see the sticky at https://www.askmehelpdesk.com/heatin...ons-58313.html
