The Airtemp furnace is a popular heating solution used by many homeowners for reliable warmth during the colder months. A critical component of this system is the pilot light, which ignites the burner to heat your home efficiently. Understanding how to manage and troubleshoot the Airtemp furnace pilot light can save time, reduce repair costs, and ensure your heating system functions smoothly all season. This article explores key aspects like how the pilot light works, common issues, and maintenance tips tailored specifically for Airtemp furnaces.

Troubleshooting Steps | Relighting the pilot, cleaning pilot area, checking thermocouple, inspecting gas supply |
Safety Precautions | Shutting off gas before maintenance, ensuring proper ventilation, avoiding gas leaks |
Understanding the Role of the Pilot Light in an Airtemp Furnace
The pilot light in an Airtemp furnace acts as a small flame that ignites the main burner when heat is required. This continuous flame is essential for efficient heating operation. Without the pilot light, the furnace cannot produce the flame necessary to warm the air circulated throughout your home.
The Airtemp furnace uses a standing pilot light system, meaning the pilot flame stays on at all times when the furnace is ready to operate. This reliable ignition method ensures the furnace heats consistently without delay.
Common Pilot Light Problems in Airtemp Furnaces
Several issues can cause the Airtemp furnace pilot light to malfunction or go out. Recognizing these problems early can prevent larger system failures and maintain furnace efficiency.
- Pilot Light Goes Out Frequently: This is commonly caused by a dirty pilot orifice, a draft blowing out the flame, or faulty gas flow.
- Weak or Flickering Flame: May indicate a clogged pilot tube or insufficient gas pressure.
- Thermocouple Failure: The thermocouple senses the pilot flame; if it malfunctions, the gas valve shuts off to prevent hazards.
- Gas Supply Issues: Interrupted gas supply or incorrect pressure can stop the pilot from igniting.
Step-by-Step Guide to Relighting the Airtemp Furnace Pilot Light
Relighting the pilot light is a common maintenance procedure that many homeowners can perform safely if done correctly.
- Turn Off the Furnace: Set the thermostat to “Off” and shut off the gas supply at the furnace.
- Wait for Safety: Allow 5-10 minutes for residual gas to dissipate before proceeding.
- Locate the Pilot Light Assembly: Usually near the burner, identifiable by a small metal tube and ignition button or knob.
- Turn the Gas Valve to “Pilot”: Press down and hold this valve to allow gas flow to the pilot.
- Ignite the Pilot: Use a long lighter or built-in igniter to light the pilot flame while holding the gas valve.
- Hold the Gas Valve for 30 Seconds: This warms the thermocouple ensuring it detects the flame.
- Release and Turn the Valve to “On”: Confirm the pilot remains lit and the furnace is ready to operate.
- Restore Thermostat Settings: Set your thermostat back to the desired temperature.
Maintaining Your Airtemp Furnace Pilot Light for Optimal Performance
Regular maintenance is crucial to keep your pilot light functioning efficiently and the furnace running smoothly.
- Clean the Pilot Orifice: Dust and debris can clog the tiny opening; use compressed air or a soft brush to clean.
- Inspect the Thermocouple: Look for wear or damage and replace it if necessary to ensure proper gas valve operation.
- Check for Gas Leaks: Use soapy water on connections to identify leaks; bubbles indicate gas escaping and require immediate repair.
- Ensure Proper Ventilation: A well-ventilated area prevents drafts from extinguishing the pilot light.
- Schedule Annual Professional Service: A certified technician can perform in-depth checks and prolong furnace lifespan.
Troubleshooting Advanced Issues With Your Airtemp Furnace Pilot Light
If basic relighting and cleaning do not solve pilot light problems, more complex troubleshooting may be necessary.

Thermocouple Testing and Replacement
The thermocouple is a safety device that shuts off the gas if the pilot light is out. Using a multimeter, test for continuity and voltage output. A failing thermocouple should be replaced to restore reliable operation.
Checking Gas Pressure and Supply
Incorrect gas pressure can prevent proper pilot light ignition. A licensed technician should measure pressure levels and inspect the gas line for blockages or leaks.
Inspecting the Pilot Assembly
The pilot assembly components, including the orifice and tubing, should be examined for signs of corrosion, soot buildup, or physical damage. Any compromised parts require replacement for safety and efficiency.
Safety Tips When Dealing With Your Airtemp Furnace Pilot Light
- Always Turn Off Gas Supply Before Maintenance: Prevent gas leaks or accidental ignition by shutting off the gas at the furnace.
- Ventilate the Area: Ensure open windows or vents when working to avoid gas buildup.
- Avoid Open Flames if You Smell Gas: If you detect a strong gas odor, do not attempt to relight. Evacuate and call professionals immediately.
- Use Proper Tools: Utilize factory-recommended parts and tools for repairs to preserve safety standards.
- Hire Licensed Technicians for Complex Repairs: Professional expertise is essential when dealing with gas components and electrical systems.
