Let’s get your furnace up and running again!

Check the Thermostat Settings

You should check if your thermostat is set to the correct temperature and mode. Sometimes, the furnace not igniting can be as simple as a wrong setting on the thermostat. So, we need to make sure that it is set correctly.

  • Check if the temperature on the thermostat is higher than the current room temperature. If it’s too low, turn up the heat by adjusting the temperature setting.
  • Next, ensure that the thermostat is set to ‘heat’ mode and not ‘cool’ or ‘off’. It’s easy to accidentally switch modes when using a programmable thermostat. If necessary, switch it back to ‘heat’ mode.
  • Additionally, double-check if your thermostat has fresh batteries and they are properly installed. Weak or dead batteries can cause issues with your furnace ignition. Replace them if needed.

If you have a smart thermostat, make sure it’s connected to Wi-Fi and functioning properly. Sometimes connectivity issues can prevent your furnace from igniting.

Inspect the Pilot Light

Check if the pilot light is on and properly lit. This is a crucial step in troubleshooting a furnace that isn’t igniting. As homeowners, we often overlook the importance of the pilot light, but it plays a vital role in initiating the combustion process. So, let’s go ahead and take a look.

Firstly, locate your furnace’s access panel. It’s usually located near the bottom of the unit. Open it up and find the pilot light assembly. You should see a small flame burning steadily if it’s functioning correctly. If not, make sure to follow proper safety procedures before attempting any repairs.

If you notice that the pilot light is out or flickering, it may need to be relit or cleaned. Carefully follow your furnace manufacturer’s instructions for relighting the pilot light, as they can vary depending on your specific model.

In some cases, even after relighting, the pilot light may continue to go out repeatedly. This could indicate an underlying issue with components like thermocouples or gas valves that require professional attention.

Remember that working with gas appliances can be dangerous, so don’t hesitate to contact a qualified technician if you’re unsure about handling any part of this process. Safety first!

Ensure Proper Gas Supply

To ensure proper gas supply, we make sure the gas valve is turned on and supplying fuel to the pilot light. Without enough gas, the furnace won’t ignite and provide warmth to our home. It’s important to regularly check the gas valve to ensure it is in the correct position. If it’s a manual valve, we turn it counterclockwise until it stops to open it fully. For automatic valves, we usually just need to flip a switch or press a button for the gas to flow.

Once we’ve confirmed that the gas valve is on, we should also inspect the pilot light itself. A weak or extinguished pilot light can be another reason why our furnace won’t ignite. We look for any signs of dirt or debris obstructing its flame. Using a small brush or compressed air, we carefully clean any buildup around the pilot light.

If everything looks fine with both the gas valve and pilot light but our furnace still isn’t igniting, it’s crucial not to attempt any further repairs ourselves. In these cases, calling a professional HVAC technician is recommended as they have the knowledge and tools necessary to safely diagnose and fix more complex issues with our heating system.

Clean or Replace the Ignitor

Once we’ve confirmed that the gas valve is on and the pilot light is clean, it’s important to inspect and potentially replace the ignitor if necessary.

The ignitor plays a crucial role in starting the furnace by creating a spark that ignites the gas. Over time, ignitors can become worn out or damaged, leading to ignition problems.

To begin with, we should visually inspect the ignitor for any signs of damage or wear. Look for cracks, discoloration, or broken wires. If any issues are found, it’s best to replace the ignitor right away.

Next, we need to test the functionality of the ignitor. This can be done using a multimeter to check for continuity. If there is no continuity in the circuit, it means that the ignitor has failed and needs to be replaced.

When replacing an ignitor, it’s important to choose one that is compatible with your furnace model. Refer to your furnace’s manual or consult a professional for guidance on selecting the correct replacement part.

Call a Professional for Assistance

If you’re unsure about how to inspect or replace the ignitor, it’s best to call a professional for assistance. Dealing with furnaces can be tricky and potentially dangerous if you don’t have the proper knowledge or experience.
