How to Replace a Rheem Electric Igniter

If you are wondering why your Rheem water heater isn't actually heating water, it could be the result of a bad thermocouple. This thermocouple is commonly referred to as an "igniter." It is the component that actually lights the gas flame once the Rheem heater is activated. Your Rheem water heater can't function without a thermocouple, so it is important you replace a faulty one as quickly as possible.

Things You'll Need

• Wrench or pliers

Instructions

1. Locate the gas valve on the water heater, and shut it off.

2. Shut off the valve on the main gas line near the heater.

3. Locate the igniter on the heater. It will be in the burner compartment located at the front of the unit and will be sitting loosely or held in place with clips.

4. Unscrew the bolt on the copper lead wire connected to the thermocouple with a wrench or pliers.

5. Unscrew the bolts on the gas tubes connected to the thermocouple.

6. Unclip the thermocouple and slide it out of the unit.

7. Fit a new thermocouple in the Rheem, and replace the gas tubes and copper lead. Turn on the gas valves.
