Customer stated furnace wouldn’t come on, home was set to 72 put thermostat to 75 and didn’t hear a click from thermostat, turned thermostat all the way up and furnance kicked on, ohms reading at 470, let furnance run until fan limit kicked in which was at 150 blower came on, after letting furnace run pulled nozzle assembly out and electrodes are very burnt back would recommend changing them, also cad cell eye very brown, and burner head was dirty cleaned everything up put it back together and furnace fired up and stayed running, furnace really just needs a good cleaning and put together estimate for parts that should be changed.
