A water heater igniter switch is a vital component in a gas-powered water heater. It is responsible for igniting the gas that heats the water in the tank. When the igniter switch fails, the water heater will not function, leaving you without hot water. In this article, we will provide a step-by-step guide on how to replace a water heater igniter switch.
Step 1: Safety Precautions
Before attempting to replace the water heater igniter switch, it is essential to take some safety precautions. Firstly, ensure that the gas supply to the water heater is turned off. This can be done by turning the gas valve handle to the off position. Additionally, you should turn off the power supply to the water heater by unplugging it or turning off the circuit breaker. Finally, allow the water heater to cool down completely before starting the replacement process.
Step 2: Remove the Access Panel
The igniter switch is located behind the access panel on the water heater. Use a screwdriver to remove the screws holding the panel in place. Carefully remove the panel to access the igniter switch.
Step 3: Locate the Igniter Switch
The igniter switch is a small rectangular device located near the bottom of the water heater. It is attached to a bracket with two screws.
Step 4: Disconnect the Wires
Before removing the igniter switch, you must first disconnect the wires. The wires are usually connected to the igniter switch with a small clip or screw terminal. Use a pair of pliers or a screwdriver to disconnect the wires from the switch.
Step 5: Remove the Igniter Switch
With the wires disconnected, you can now remove the igniter switch from the bracket. Use a screwdriver to remove the two screws holding the switch in place. Carefully remove the switch from the bracket.
Step 6: Install the New Igniter Switch
Take the new igniter switch and attach it to the bracket using the two screws. Ensure that the switch is securely fastened to the bracket.
Step 7: Connect the Wires
With the new switch in place, you can now reconnect the wires. Follow the instructions provided with the replacement switch to ensure that the wires are connected correctly.
Step 8: Test the Water Heater
Once you have connected the wires, you can now test the water heater. Turn on the gas supply to the water heater and then turn on the power supply. Wait for a few minutes to allow the water heater to warm up. If the water heater ignites and begins to heat the water, then the replacement was successful.
Conclusion
Replacing a water heater igniter switch is a straightforward process that can be completed by following the steps outlined in this article. Remember to take the necessary safety precautions before starting the replacement process and ensure that you have the correct replacement switch for your water heater model.
