My Nordyne furnace was turning on then off before the fan would kick in. I can see the flames going into the heat exchanger but then they would shut off after 5 seconds or so. It would do this a few times until the fan turns on and starts to heat the house. I figured its a dirty flame sensor so I cleaned it up with sand paper as there was soot on both ends. Operation was better and the system would turn on the first try but now it is starting to do the same thing, not as bad as before but I want to avoid it from getting worse.
What would you do?
A. Change flame sensor. ($43)
B. Maybe the limit switch is bad? ($11)
C. Something else is going on.
