Lighting the pilot light on a furnace is a task that typically involves following a set of safety measures and instructions specific to your furnace model. However, I’ll provide you with a general step-by-step guide that applies to most furnace units. Always consult your furnace’s manual for specific instructions and safety information. If you don’t feel comfortable performing these steps or if they don’t work, contact a qualified HVAC professional.
Step 1: Locate the Furnace Instructions
Check the user’s manual or look for a sticker with instructions on the furnace. This sticker is often near the pilot light and provides model-specific instructions.
Step 2: Ensure Safety Before You Start
Before attempting to light the pilot light, make sure you have turned the thermostat to the lowest setting or turned it off completely. Wait at least five minutes to clear out any gas fumes which might create a dangerous situation.
Step 3: Turn Off the Gas
Find the gas valve and turn it to the “Off” position. Wait a few minutes to prevent any residual gas from igniting.
Step 4: Locate the Pilot Light Assembly
Locate the pilot light assembly that typically has a gas valve with “On”, “Off”, and “Pilot” settings. There will also be a reset button and the pilot light itself. The pilot light may be behind a panel that needs to be removed.
Step 5: Prepare to Light the Pilot
Turn the valve to the “Pilot” position. Hold a long match or a barbecue lighter next to the pilot light opening.
Step 6: Ignite the Pilot Light
While holding the reset button (or following the instructions on your furnace), light the pilot light. You might need to keep holding the reset button for up to a minute until the thermocouple warms up which will keep the pilot light lit after you release it.
Step 7: Keep the Furnace Running
Once the pilot light stays lit after you release the reset button, turn the gas valve back to the “On” position. The furnace should start automatically if the thermostat is set to call for heat.
Step 8: Replace any Panels and Set Thermostat
Replace any panels you removed during the process. Finally, set your thermostat to your desired setting and ensure that the furnace functions as expected.
Professional Help
If the pilot light won’t stay lit or you smell gas, stop immediately and call a professional. It could indicate a faulty thermocouple or a more serious issue.
Important Safety Tips
Always be aware of the smell of gas, which often smells like rotten eggs, and if you notice this odor, evacuate the area and contact your gas company or a professional technician. Don’t attempt to light the pilot light if you smell gas or are unsure about the procedure.
By following these instructions, you should be able to safely and successfully light the pilot light on your furnace. Remember, if at any point you feel unsure or smell gas, stop what you’re doing and consult a professional.
