5. คำแนะนำในการติดตั้ง

สำคัญ: Installation should only be performed by a qualified HVAC technician. Failure to follow these instructions can result in property damage, personal injury, or death.

1. ความปลอดภัยเป็นสิ่งสำคัญที่สุด: Turn off all electrical power to the furnace at the main service panel. Close the manual gas shut-off valve to the furnace.
2. Access Ignitor: Locate and remove the furnace access panel(s) to expose the burner assembly and ignitor.
3. ถอดปลั๊กอุปกรณ์จุดไฟตัวเก่า: Carefully disconnect the wiring harness from the old ignitor. Note the routing of the wires.
4. ถอดตัวจุดระเบิดเก่าออก: Unscrew or unclip the old ignitor from its mounting bracket. Handle it gently as it may be fragile.
5. ตรวจสอบการติดตั้ง: Examine the mounting bracket for any damage or corrosion. Clean if necessary.
6. ติดตั้ง Ignitor ใหม่: Carefully mount the new MARS 67915 ignitor onto the bracket using the original hardware or suitable replacements. Ensure it is securely fastened and positioned correctly according to the furnace manufacturer's specifications. Avoid touching the black ignitor element.
7. การเชื่อมต่อสายไฟ: Connect the new ignitor's wiring harness to the furnace control board or existing wiring, ensuring a secure and correct connection. The MARS 67915 comes with 36-inch leads and a connector for direct replacement.
8. แผงการรักษาความปลอดภัย: Replace all furnace access panels securely.
9. คืนพลังงานและก๊าซ: Open the manual gas shut-off valve. Restore electrical power to the furnace.
10. การดำเนินการทดสอบ: Initiate a call for heat at the thermostat and observe the furnace's ignition sequence to ensure the new ignitor glows and ignites the gas burner properly.

6. หลักการทำงาน

The MARS 67915 is a hot surface ignitor. When the furnace calls for heat, the control board sends voltage to the ignitor, causing its silicon carbide element to heat up rapidly to a very high temperature (typically over 1800°F or 980°C). Once the ignitor reaches its optimal temperature, the gas valve opens, allowing gas to flow over the hot ignitor, which then ignites the gas. After successful ignition, the ignitor typically de-energizes, and the flame sensor confirms the presence of a flame.

7. การบำรุงรักษา

The MARS 67915 ignitor is a sealed component and does not require routine user maintenance. However, regular professional furnace maintenance is recommended to ensure optimal performance and longevity of all furnace components, including the ignitor.

• During annual furnace inspections, a qualified technician should visually inspect the ignitor for cracks, discoloration, or signs of wear.
• Ensure the area around the ignitor and burner assembly is free from dust, debris, and obstructions.

8 การแก้ไขปัญหา

If your furnace is not igniting, and you suspect the ignitor, consider the following common issues. Always ensure safety precautions are followed before any inspection.

• Ignitor Not Glowing:
  • Check for power to the furnace.
  • Verify wiring connections to the ignitor are secure.
  • The ignitor itself may be faulty or broken. A qualified technician can test its resistance.
• Ignitor Glows but No Ignition:
  • Check if the gas supply to the furnace is open.
  • Ensure the ignitor is positioned correctly to ignite the gas stream.
  • There might be an issue with the gas valve or furnace control board.
  • The ignitor may not be reaching sufficient temperature to ignite the gas.
• Furnace Cycles On and Off Rapidly: This could indicate a problem with the flame sensor, which works in conjunction with the ignitor.

For complex issues, it is highly recommended to contact a certified HVAC professional.
