Pilot Light Problems
Having trouble with your Nordyne furnace? Pilot light problems are common. This issue can disrupt your furnace’s functionality. Resolving it quickly is crucial for your comfort. Let’s explore some key areas to troubleshoot.
Relighting Pilot
If your pilot light goes out, relighting it is the first step. Locate the pilot light assembly. Turn the gas valve to the “off” position. Wait for five minutes to clear any gas. Switch the valve to “pilot.” Use a lighter or match to ignite the pilot light. Hold the reset button for about 30 seconds. Release the button and check if the pilot stays lit.

Checking Gas Supply
Your furnace needs a steady gas supply. Ensure the gas valve is open. Check if other gas appliances work. If not, the gas supply might be interrupted. Inspect the gas line for any visible damage. Call your gas provider if you suspect an issue. If the gas supply seems fine, but the pilot still won’t light, there could be a blockage. Dirt or debris can obstruct the gas flow. Clean the pilot light opening with a needle or wire.
Flame Sensor Issues
Flame sensor issues can cause your Nordyne furnace to stop working. The flame sensor detects if the burner is lit. If it fails, the furnace may shut down. This can lead to no heat in your home. Let’s explore how to troubleshoot these issues.
