I shut the furnace off and turn it back on the ignitor lights the furnace fires up for a few seconds then shuts back down repeats itself 3 times then stops. I am getting 7 flashes. Don't understand issue or whats wrong because ignitor is firing up furnace?

HVAC Technician: Bill, HVAC Technician replied 8 years ago

the furnace tried to light three times and failed, try to clean the sensor with steel wool or fine sandpaper, also remove the sensor wire from the ignition control and than put it back. Here's examples of sensors:Examples for furnace sensors
