2. Sikkerhedsoplysninger

ADVARSEL: Forkert installation, justering, ændring, service eller vedligeholdelse kan forårsage skade på ejendom, personskade eller død. Læs installations-, betjenings- og vedligeholdelsesinstruktionerne grundigt, før du installerer eller servicerer dette udstyr.

• Always disconnect electrical power to the furnace before performing any service or maintenance.
• Working with gas appliances can be hazardous. If you are not qualified to perform these procedures, contact a certified HVAC technician.
• Brug passende personlige værnemidler (PPE), såsom handsker og øjenbeskyttelse.
• Ensure all gas connections are properly sealed and tested for leaks after any work involving gas lines.
• Omgå ikke nogen sikkerhedsanordninger.

3. Produktet er slutview

The flame sensor is a safety device in a gas furnace that detects the presence of a flame in the burner assembly. If the sensor does not detect a flame after the gas valve opens, it signals the furnace control board to shut off the gas supply, preventing unburnt gas from accumulating. This specific sensor is an upgraded replacement for Trane part number SEN01114.

This image displays the Trane Furnace Flame Sensor PSE-T19. It features a white ceramic insulator body, a metal mounting bracket with a screw hole, and a metal rod that extends into the flame path to detect the presence of a flame.

4. Opsætning og installation

Installation of the flame sensor should only be performed by a qualified technician. The following steps are for informational purposes only.

1. Afbryd strømmen: Sluk for al strøm til ovnen på hovedservicepanelet.
2. Locate Sensor: Identify the existing flame sensor. It is typically a single metal rod positioned in the flame path of the burner assembly, often secured by one screw.
3. Fjern den gamle sensor: Carefully disconnect the wire leading to the sensor. Remove the screw holding the sensor in place and gently pull the old sensor out.
4. Installer ny sensor: Insert the new Trane PSE-T19 flame sensor into the same position. Ensure the metal rod is correctly positioned to be enveloped by the flame during operation. Secure it with the mounting screw.
5. Tilslut ledninger: Reconnect the wire to the new flame sensor. Ensure the connection is secure.
6. Gendan strøm: Tænd for den elektriske strøm til ovnen.
7. Test drift: Initiate a heating cycle and observe the furnace's ignition sequence. The main burners should ignite and remain lit.

5. Driftsprincipper

When the furnace calls for heat, the igniter heats up, and the gas valve opens. As the gas ignites, the flame sensor, which is a small metal rod, becomes exposed to the flame. The flame rectifies a small alternating current (AC) into a direct current (DC) signal. This DC signal is sent to the furnace's control board, confirming the presence of a flame. If the control board does not receive this signal within a few seconds of ignition, it will shut off the gas supply as a safety measure, preventing unburnt gas from accumulating in the combustion chamber.

6. Vedligeholdelse

Regular maintenance of the flame sensor is crucial for reliable furnace operation. A dirty flame sensor is a common cause of furnace malfunctions.

• Rensning: Annually, or if experiencing ignition issues, carefully remove the flame sensor. Use fine-grit sandpaper or steel wool to gently clean off any carbon buildup or oxidation from the ceramic insulator and the metal rod. Do not use harsh chemicals or abrasive cleaners that could damage the sensor.
• Inspektion: While cleaning, inspect the sensor for any signs of physical damage, such as cracks in the ceramic, corrosion, or a bent rod. Replace the sensor if any damage is observed.
• Geninstallation: Reinstall the cleaned sensor, ensuring it is securely mounted and the wire connection is tight.

7. Fejlfinding

If your furnace is experiencing issues related to ignition or short cycling, the flame sensor may be a contributing factor.

• Furnace Ignites, then Shuts Off (Short Cycling): This is a classic symptom of a dirty or faulty flame sensor. The sensor detects the flame initially but then loses the signal, causing the furnace to shut down.
• Furnace Fails to Ignite: While many factors can cause this, a completely failed flame sensor can prevent the furnace from even attempting to keep the gas valve open.

Trin til fejlfinding:

1. Clean the Flame Sensor: Follow the cleaning instructions in Section 6. This resolves most flame sensor-related issues.
2. Tjek ledninger: Ensure the wire connecting the flame sensor to the control board is secure and free from damage.
3. Undersøg for skader: Look for any visible damage to the sensor itself.
4. Test for Continuity (Advanced): A qualified technician can use a multimeter to test the sensor's continuity and signal output.
5. Udskift sensor: If cleaning and inspection do not resolve the issue, and the sensor is suspected to be faulty, replace it with a new Trane PSE-T19 or equivalent part.
