How to Troubleshoot a Nordyne Gas Heater

Save

Nordyne is a company with a long history of making furnaces. Despite a reputation for dependability, Nordyne’s furnaces aren’t exempt from basic problems inherent in most home furnace systems. Basic troubleshooting may negate the need to call a technician.

Things You'll Need

  • New switch
  • Ohmmeter
  • Screwdriver
  • Set the system’s blower to the “off” position if your system is blowing cold air. This indicates a burned out control switch. Simply purchase a new switch from a Nordyne dealer and replace it, according to the package’s directions. If the blower doesn’t quit after a heating cycle, shut down the power leading to the furnace on the circuit breaker panel and check the wiring to the switch box with an ohmmeter. If there’s a bad wire, replace the wire. As this is complicated, calling a technician is advisable.

  • Locate and adjust the anticipator if your Nordyne furnace frequently keeps turning on and off. Depending on the particular model, the anticipator – the mechanism responsible for shutting the unit down if the blower continues output past a predetermined time – is located on the thermostat. It’s a small lever with a scale of one to six with six being the highest setting. Adjust the lever to set the indicator above three or four if the indicator is set to one or two. This automatically adjusts the timer to a longer blow time versus shorter bursts.

  • Depress and hold the pilot light test switch if your furnace won’t light or stay lit longer than a few seconds. Watch the igniter; a blue spark should ignite the burner. If not, the igniter needs replacing. With the power cut and unit off, unscrew the housing screws at the base of the igniter and slowly pull it out. Replace it with a new one and screw it into place. A replacement is typically sold at many home improvement centers or independent Neodyne dealers.
