Blog Furnace Quick & Easy Trane troubleshooting guide for your furnaces Key Takeaways Goodman furnaces are known for their reliability, but they can experience issues like any mechanical device. Common problems include ignition failures due to worn-out ignitors, gas supply issues, or dirty flame sensors. Persistent operation or frequent cycling could be due to an improperly calibrated thermostat. Regular maintenance and basic troubleshooting can resolve many of these problems, but persistent issues may require professional assistance. 2024-05-17 // 7 min Read Asif Engineer-in-Training & Apprentice If you’re a Trane furnace owner, you know what it stands for and how important it is to have it in good working condition. However, it is an electric device – probably the most used one in your home and it can face issues from time to time.This is why, we’ve written a helpful guide for troubleshooting your Trane furnace and understanding what’s wrong with it and when to call a professional for its repair. We’ll be discussing all the common issues that you may be facing with your Trane furnace along with its popular error codes. Step-by-Step Guide to Troubleshooting Trane Furnace Issues Troubleshooting a Trane furnace effectively requires following a structured process to understand and rectify problems that could stop the unit from functioning properly or efficiently. Here’s an in-depth guide to help you troubleshoot common Trane furnace issues:- 1. Inspecting the Thermostat The first step is often the simplest: checking the thermostat. A malfunction here can indicate more severe problems within the furnace.Power Supply: Confirm that the thermostat is powered, which might involve changing batteries if it operates on battery power.Settings Verification: Make sure the thermostat is switched to "heat" mode and the temperature setting is at least five degrees higher than the current room temperature.Programming: For programmable thermostats, ensure the heating schedule aligns with your needs. Incorrect settings can prevent the system from activating when needed. 2. Assessing the Air Flow of the Furnace Improper airflow can cause the furnace to overwork, reducing both efficiency and lifespan.Vent Inspection: Make sure all household vents are open and not obstructed.Filter Check: Inspect the furnace filter, a frequent source of airflow problems. Locate the filter, typically near the blower section, and replace or clean it based on whether it's disposable or permanent. 3. Verify Power Supply and Electrical Connections If your furnace isn't starting, it often could indicate that it suffers from power-related issues.Furnace Switch: This switch, generally found on or near the furnace, should be set to the ON position.Circuit Breaker: Inspect your home’s main electrical panel for any tripped breakers or blown fuses. Reset breakers or replace fuses as required. 4. Inspect Flame and Burner Condition The condition of the burner directly impacts the furnace's heating capability.Burner Inspection: Through the sight glass, observe the burner flames; blue indicates normal operation, while yellow suggests a need for cleaning or replacement.Burner Maintenance: Ensure the furnace is off and the gas supply is disconnected before cleaning burners using a vacuum or brush. 5. Pilot Light and Ignition System Checks For furnaces with a pilot light or an electronic ignition, problems in this area can prevent heating.Pilot Light Maintenance: If your furnace has a pilot light, make sure that it is working or lit. If it's out, follow the manufacturer’s instructions to relight it.Electronic Ignition Issues: If your furnace uses electronic ignition and fails to start, this could indicate an ignition problem, typically a task for an HVAC professional. 6. Evaluate the Blower Motor and Inducer Motor These motors are crucial for circulating air and venting exhaust gases.Listen for Noises: Unusual noises like grinding or screeching can indicate mechanical issues.Visual Inspection: Check for signs of wear or damage. Faulty capacitors, which help in motor start-up, can cause humming sounds if they fail. 7. Furnace Control Board and Error Codes The control board is central to furnace operations and safety measures.Error Code Analysis: Many Trane furnaces display error codes through an LED light pattern to indicate specific issues. Check out the fault code guide given in the next section for more details.Board Examination: Inspect the control board for signs of damage or corrosion. Handling the board should be done cautiously to avoid damage from static electricity. 8. System Reset Sometimes, resetting the system can solve all the electronic glitches or issuesPower Cycling: Turn off the furnace using the thermostat and main switch, wait a few minutes, then power it back on to reset the system. 9. Gas Supply and Valve Checks Adequate gas flow is important for effective heating in your home.Valve Inspection: Make sure the gas valve is open and check for any signs of malfunction or blockage.Gas Leak Precautions: If you detect a gas smell near the furnace or if your carbon monoxide detector goes off, shut the HVAC system off, leave the area, and contact a professional immediately.

Professional assessment is recommended due to the component’s complexity. LED Off ContinuouslyMeaning: The control board is not receiving power.Required Action: Verify the power sources, including the furnace switch and circuit breakers. Continued problems might indicate a control board malfunction requiring expert diagnosis.

Four Flashes of LEDMeaning: High-temperature limit circuit is open.Required Action: Typically due to an overheating condition from restricted airflow. Ensure vents are unblocked and filters are replaced to facilitate proper airflow. It is important to know the error codes for your trane furnace to fix problems quickly. Here are a few of the most common trane furnace error codes, what they mean, and how to fix them: Five Flashes of LEDMeaning: Detection of flame when none should exist.Required Action: Likely issues with the flame sensor or gas valve. It is advisable to consult with a professional to handle potential gas-related hazards. Six Flashes of LEDMeaning: Incorrect line voltage polarity or low voltage.Required Action: Confirm adequate voltage and correct wiring polarity. Electrical issues should be addressed by qualified technicians. Seven Flashes of LEDMeaning: Error in the gas valve circuit.Required Action: Examine the gas valve’s functionality and power supply. Ensure the gas flow is consistent and unimpeded. Eight Flashes of LEDMeaning: Insufficient flame strength detected.Required Action: This could stem from low gas pressure, sensor issues, or burner complications. Clean the flame sensor if dirty and check that gas pressure meets specified levels. Nine Flashes of LEDMeaning: Problem within the igniter circuit.Required Action: Check for damage or wear on the igniter and replace it if defective.
