How to replace the igniter in my Goodman GMVC95 gas furnace for reliable ignition?
Replacing the igniter in your Goodman GMVC95 gas furnace can help ensure reliable ignition and proper heating operation. Igniters can wear out over time and may need replacement if your furnace is having trouble starting. Here are the steps to replace the igniter:
Safety Precautions:
1. Turn Off Gas and Electricity: Shut off the gas supply to the furnace and turn off the electrical power at the breaker or disconnect the switch.
2. Wear Safety Gear: Use appropriate safety gear, including gloves and safety goggles.
Check for Gas Leaks: Before proceeding, check for any gas leaks by performing a soap bubble test on gas connections.
Steps to Replace the Igniter:
1. Access the Furnace:
Remove the access panel(s) to gain access to the internal components of the furnace.
Follow safety guidelines to prevent electrical shock or gas leaks.
2. Locate the Old Igniter:
The igniter is typically located near the burner assembly and is a small, rod-shaped component.
3. Disconnect Wiring:
Carefully disconnect the wiring connected to the igniter. Make sure to note or label the wires for reconnection later.
4. Remove the Old Igniter:
The igniter may be held in place with a retaining bracket or screws. Remove any fasteners securing it.
Carefully detach the old igniter from its mounting position.
5. Install the New Igniter:
Position the new igniter in the same location and orientation as the old one.
Secure it to the mounting bracket or reattach any screws.
6. Reconnect Wiring:
Reconnect the wiring to the new igniter as noted or labeled earlier.
7. Perform Leak Check:
Apply a soap bubble test to the gas connections to ensure there are no leaks.
8. Reassemble the Furnace:
Reinstall the access panel(s) and ensure they are securely fastened.
9. Turn On Gas and Electricity:
Carefully turn on the gas supply and restore power to the furnace.
10. Test the Furnace:
Turn on the furnace and test its operation.
Monitor the furnace for reliable ignition. The igniter should glow red-hot when the furnace attempts to start.
11. Monitor Performance:
Keep an eye on the furnace's performance over the next few days to ensure it's operating reliably and efficiently.
12. Regular Maintenance:
Make a note of the date when you replaced the igniter. Igniters are consumable parts and may need replacement every few years. Regular maintenance can help prevent ignition issues in the future.
If you are not experienced in working with gas furnaces or if you encounter any difficulties during the process, it's advisable to consult a licensed HVAC technician. They can ensure the replacement is done correctly and safely, avoiding potential gas leaks, electrical hazards, or other problems. Additionally, a technician can inspect the furnace for any other issues that may be affecting its performance and safety.
