How to replace a hot surface gas igniter A.O. Smith water?
Replacing a hot surface gas igniter in an A.O. Smith water heater is a relatively straightforward process that can be done by most DIY enthusiasts. The hot surface igniter is a crucial component that generates the heat necessary to ignite the gas burner in your water heater. If it's not working correctly, it can lead to a lack of hot water. Here's a step-by-step guide on how to replace it:
Before you begin:
* Safety First: Ensure the gas supply to the water heater is turned off, and the water heater has cooled down to avoid any accidents.
* Gather Tools: You'll need a few basic tools for this job, including a screwdriver, pliers, and a replacement hot surface igniter suitable for your A.O. Smith water heater model.
Step 1: Access the Hot Surface Igniter
1. Locate the access panel on your A.O. Smith water heater. This is typically at the front of the unit near the bottom.
2. Remove the screws or fasteners securing the access panel in place using a screwdriver or pliers.
Step 2: Disconnect the Old Igniter
1. Once you have access to the igniter, carefully disconnect the wires connected to it. There are usually two wires attached to the igniter. Use pliers to gently pull off the wire connectors. Be sure to remember the placement of each wire for reassembly.
2. If your hot surface igniter is secured with screws, remove these screws using a screwdriver.
3. Carefully take out the old igniter from its position.
Step 3: Install the New Igniter
1. Position the replacement hot surface igniter in the same spot where the old one was located.
2. If it's held in place by screws, secure it with the screws you removed earlier.
3. Reattach the wires to the new igniter. Ensure that you connect them to the correct terminals. The wires usually have connectors that make it easy to attach them securely.
4. Double-check the connections to ensure they are snug and secure.
Step 4: Reassemble the Water Heater
1. Reattach the access panel to the water heater and secure it with the screws or fasteners you removed earlier.
2. Make sure the panel is firmly in place to prevent any air leaks.
Step 5: Turn on the Gas and Test
1. Turn the gas supply back on to the water heater.
2. Set your water heater to its pilot or ignition position and observe the hot surface igniter. It should start glowing red as it heats up.
3. If the igniter glows red and the burner lights, your replacement was successful.
4. If it doesn't light or the igniter doesn't glow, turn off the gas supply immediately and recheck your connections.
Step 6: Final Checks
1. Once you've confirmed that the hot surface igniter is working correctly and the burner is lit, check for any gas leaks around the connections.
2. If everything is in order, you can set your water heater to your desired temperature and enjoy hot water.
In summary, replacing a hot surface gas igniter in an A.O. Smith water heater involves turning off the gas, accessing the igniter, disconnecting the old one, installing the new one, reassembling the unit, and testing it to ensure it functions correctly. If you're uncomfortable with any part of this process or encounter any difficulties, it's best to consult a professional plumber or technician to ensure a safe and successful replacement.
