Where Is the Pilot Light on a Bryant Furnace

The pilot light location on a Bryant furnace can vary by model, age, and installation type. This article explains how to find the pilot light, identify the pilot assembly, safely relight it, troubleshoot common pilot issues, and know when to call a professional. The guidance applies to typical Bryant gas furnaces found in U.S. homes and focuses on safety and accurate identification.

Bryant Model Type	Typical Pilot Location	Notes
Older Floor-Standing Units	Lower front access panel near burner	Often visible without removing major components
Basement/Closet Wall-Mounted	Front lower service panel behind control door	May require removing two screws
Mid-Efficiency Condensing Units	Hot surface ignition or electronic ignition — no standing pilot	Look for ignition module, not a pilot light
High-Efficiency Sealed Combustion	No pilot; uses direct spark or HSI	Relighting pilot not applicable

Pilot Light Versus Electronic Ignition: Know The Difference

Modern Bryant furnaces increasingly use electronic ignition systems such as hot surface igniters (HSI) or direct spark igniters instead of a standing pilot light. If the furnace has HSI or direct spark, there is no pilot light to locate.

Signs a Bryant furnace likely has no pilot light include a sealed combustion chamber, PVC venting for condensate, or a model labeled as high-efficiency. Older, less-efficient furnaces are more likely to have a standing pilot.

Where To Look For The Pilot Light On Common Bryant Models

Locate the model and serial number on the data plate, usually on the furnace cabinet or inside the access panel. Identifying the model helps determine whether a pilot exists and where it sits.

Floor-Standing or Older Bryant Furnaces

On many older Bryant floor furnaces, the pilot light is near the burner assembly, behind the lower front access panel. Look for a small metal tube (pilot tube) and a thermocouple or flame sensor adjacent to the burner.

Closet-Mounted or Wall Furnaces

Closet or wall-mounted Bryant units commonly place the pilot behind a small control access door. Remove the panel screws and shine a flashlight; the pilot or pilot assembly will be near the burners at the base.

Mid- and High-Efficiency Bryant Furnaces

Mid- and high-efficiency Bryant furnaces often use HSI or direct spark igniters. These systems have no pilot light. Instead, inspect the control area for an igniter module, a ceramic HSI rod near the burners, or a small spark electrode.

Identifying Pilot Components

Recognizing the pilot components helps avoid confusion: the pilot tube is a thin metal tube delivering gas; the pilot burner is a small nozzle where the pilot flame burns; the thermocouple is a sensor that detects the pilot flame and signals the gas valve.

In many Bryant units, the thermocouple is a copper or nickel-plated rod positioned in the pilot flame with a wire that connects to the gas valve. A faulty thermocouple is a common reason a pilot won’t stay lit.

How To Safely Relight A Bryant Furnace Pilot Light

Follow the furnace manufacturer’s instructions printed on the appliance label. The following steps present a general, safety-focused procedure. Do not attempt if the unit uses electronic ignition — instead follow reset procedures in the manual.

1. Turn Off The Gas And Power: Switch off the furnace at the thermostat and turn off electrical power at the switch or breaker.
2. Shut Gas Valve To Pilot: Locate the gas control knob on the gas valve; set to “Off” and wait five minutes to clear gas from the combustion chamber.
3. Access The Pilot Assembly: Remove the lower front panel or control access door to expose the burner and pilot area.
4. Set Gas Valve To Pilot: Turn the gas valve to the “Pilot” position and press/hold the knob in to allow gas to reach the pilot.
5. Light The Pilot: Use a long-reach lighter or match while holding the knob. When the pilot lights, continue holding the knob for 20–60 seconds to heat the thermocouple.
6. Release And Test: Slowly release the gas knob. If the pilot remains lit, turn the valve to “On” and replace access panels. Restore power and set thermostat.

Troubleshooting Common Pilot Problems

If the pilot fails to stay lit, these are the most frequent causes: dirty pilot orifice, weak thermocouple, faulty gas valve, or drafts blowing out the pilot.

Pilot Won’t Light

Possible causes include an obstructed pilot orifice, no gas supply, or a closed gas valve. Check other gas appliances to confirm gas supply. If only the furnace lacks gas, the gas valve or internal supply may be the issue.

Pilot Lights But Goes Out When Released

This typically indicates a failing thermocouple or improper thermocouple position. The thermocouple tip must be centered in the pilot flame to produce sufficient millivoltage to keep the gas valve open.

Pilot Is Weak Or Yellow

A proper pilot flame should be steady and blue with a small inner cone. A yellow or flickering flame suggests dirty orifices, combustion air issues, or draft problems that should be addressed for safety and efficiency.

Maintenance Steps To Keep The Pilot Reliable

Regular maintenance increases reliability and safety. Bryant recommends annual professional inspection. Homeowners can perform simple tasks between service calls.

• Keep The Area Clean: Remove dust and debris from around the burner and pilot assembly.
• Inspect And Clean The Pilot Orifice: A clogged orifice can be cleaned with compressed air or a fine wire while the gas is off.
• Check Thermocouple Position: Ensure the thermocouple tip sits fully in the pilot flame.
• Test For Drafts: Secure any gaps in the furnace cabinet or nearby walls that create drafts.

When The Furnace Uses Electronic Ignition

If a Bryant furnace uses a hot surface igniter or direct spark, relighting a pilot is not applicable. Common indicators include PVC venting, a sealed combustion box, or a label indicating 90%+ AFUE efficiency.

For electronic ignition issues, troubleshooting focuses on the igniter, control board, flame sensor, wiring, and gas valve. Attempting to light a fake pilot can be dangerous and should be avoided.

Safety Tips And Carbon Monoxide Awareness

Always follow these safety precautions: turn off power before accessing components, ventilate any smell of gas by leaving the area and calling the gas company if required, and never ignore a persistent gas odor.

Install and maintain carbon monoxide detectors in the home. A malfunctioning pilot or burner can increase CO risk. If the furnace produces soot, has a yellow flame on a normally blue flame unit, or occupants feel symptoms of CO exposure, shut the unit off and seek immediate professional help.

How To Identify Model-Specific Information

Locate the furnace data plate for model, serial number, and technical specifications. Use that model information to consult Bryant manuals, the Bryant website, or trusted HVAC documentation for exact pilot location and relighting steps.

Manufacturer manuals often include diagrams showing pilot assembly location, wiring, and part numbers, which are invaluable for ordering replacement thermocouples or orifices.

When To Call A Professional HVAC Technician

Call a licensed HVAC technician if the pilot will not stay lit after cleaning and thermocouple replacement, if the gas valve is suspected faulty, or if there are repeated combustion irregularities.

Professional service is recommended for sealed combustion, high-efficiency furnaces, control board issues, or any situation involving complex gas valve or venting repairs. Qualified technicians ensure safe repairs and compliance with local codes.

Replacement Parts And Costs

Common replacement parts include thermocouples, pilot tubes, pilot assemblies, gas valves, and igniters for electronic systems. Prices vary: a thermocouple often costs $10–$50, while a gas valve or control board can range from $200–$800 plus labor.

Obtain part numbers from the furnace data plate and confirm compatibility. For warranty-covered units, check with Bryant or the installing contractor before purchasing parts.
