My Nordyne heater in my Manufactured home has been working great for 20 years, then one day the fan kept running forever without the burner on, and when it turned on and off, the clicks were really loud, when I took the cover off, I found a blinking red light, reading the cover one blink meant limit switch, or so I thought. I replaced a limit switch, and everything worked good for a few days, then the same blinking light as before, Reading the wiring diagram I see there are two limit switches, I order and replace the second one, still not working. at this point I am reading the cover again and finally I see rapid blinking, control board before the key of what all the blinks mean, I finally order this circuit board, and this is what fixed it. I just became a Nordyne heater technician!
