4. 안전 정보
경고: Installation and servicing of heating equipment can be hazardous due to gas and electrical components. Only qualified service personnel should install, repair, or service heating equipment. Failure to follow this warning could result in fire, explosion, electrical shock, property damage, personal injury, or death.
- Always disconnect electrical power to the furnace before beginning any installation or service.
- Turn off the gas supply to the furnace before working on the igniter.
- Handle the igniter carefully. The ceramic element is fragile and can break easily if dropped or mishandled.
- Do not touch the ceramic element with bare hands, as oils from your skin can reduce its lifespan.
- 설치 후 모든 연결 부분이 안전하고 적절하게 절연되어 있는지 확인하세요.
5. 설치/설정
The following are general steps for replacing a gas furnace igniter. Specific procedures may vary by furnace model. Refer to your furnace's service manual for detailed instructions.
- 전력과 가스를 차단하세요: Turn off the electrical power to the furnace at the circuit breaker and close the manual gas shut-off valve.
- Access Igniter: 보일러 점검 패널을 찾아 제거하여 버너 어셈블리와 점화기를 노출시키십시오.
- 기존 점화 장치를 분리하세요: Carefully disconnect the electrical connector from the old igniter. Remove any mounting screws or clips holding the igniter in place.
- 기존 점화 장치를 제거하십시오: Gently pull the old igniter out of its mounting bracket.
- 새로운 Igniter를 설치하세요: Carefully insert the new 1017743S igniter into the mounting bracket. Secure it with the original screws or clips. Ensure the ceramic element is positioned correctly according to your furnace's specifications.
- 배선 연결: Plug the new igniter's electrical connector securely into the furnace's wiring harness.
- 전력 및 가스 복구: Replace all access panels. Turn on the gas supply and restore electrical power to the furnace.
- 테스트 작업: Initiate a call for heat to verify the igniter functions correctly and the furnace lights properly. Observe the igniter glow and the burner ignition.
6. 사용 설명서
The 1017743S Gas Furnace Igniter operates automatically as part of your furnace's ignition sequence. When the thermostat calls for heat:
- The igniter receives power and begins to heat up, glowing bright orange.
- Once the igniter reaches a sufficient temperature, the gas valve opens, allowing gas to flow over the hot surface igniter.
- The gas ignites, and the main burners light.
- The igniter then de-energizes and cools down until the next call for heat.
7. 유지관리
The gas furnace igniter typically requires minimal maintenance. However, periodic inspection during routine furnace servicing is recommended:
- Visually inspect the ceramic element for cracks, chips, or signs of excessive wear.
- Check the wiring for any signs of fraying, burning, or loose connections.
- Ensure the igniter is securely mounted and properly positioned.
If any damage is observed, the igniter should be replaced by a qualified technician.
8. 문제 해결
If your furnace is not igniting, the igniter may be a potential cause. Common symptoms of a faulty igniter include:
- No Glow: The igniter does not glow bright orange when the furnace attempts to start.
- Intermittent Glow: The igniter glows intermittently or weakly.
- Cracked or Broken Element: Visible damage to the ceramic igniter element.
- Furnace Cycles On and Off: The furnace attempts to ignite but fails, leading to repeated cycling.
If you suspect the igniter is faulty, it should be tested and replaced by a qualified HVAC technician.
