Your Rheem water heater reliably provides hot water for hot showers, relaxing baths, and daily activities. However, if you’ve noticed that the Rheem water heater has no status light blinking like it should, don’t worry. You’re not alone in facing this problem. We’re here to help you understand why your Rheem water heater’s status light isn’t blinking and how to fix it. In this easy-to-follow guide, we’ll explore the possible causes of this problem and provide step-by-step solutions for each.

01. Combination Gas Control Turned Off

The combination gas control is the heart of your water heater’s operation. If switched off, your status light won’t blink, and your water heater won’t function.


If you have turned off your water heater’s combination gas control, causing the no status light to blink and the heater not to work, follow these simple steps to address the issue:

1. Locate the Gas Control: Find the combination gas control on your water heater. It’s usually a knob or switch that controls the gas supply. Refer to your water heater’s manual if you know its location.

2. Turn On the Gas Control: Carefully turn the gas control knob to the “ON” position. You may need to press it while turning it on. If it is off, gas flow into the water heater should be allowed.

3. Wait and Observe: After turning on the gas control, wait a few moments to allow the gas to flow and the pilot to ignite. Keep an eye on the status light to see if it starts blinking as it should.

4. Relight the Pilot (if necessary): If the pilot light went out when the gas control was off, you might need to follow your water heater’s manual instructions to relight it. Typically, this involves turning the gas control to the “Pilot” position and using a long lighter or match to ignite the pilot flame.

5. Monitor for Status Light: Watch the status light once the pilot is lit and the gas control is on. It should start blinking if everything is functioning correctly.

6. Regular Check: To avoid future problems, inspect the gas control occasionally and ensure it stays turned to the “ON” position.

02. The Pilot Is Not Lit

A pilot light that’s lit properly is crucial for your water heater to work. If your pilot isn’t on correctly, your status light will remain off.


If your pilot light isn’t igniting correctly and it shows no status light, follow these steps to fix it:

1. Safety First: Before attempting any repairs, turn off the gas supply to your water heater and wait a few minutes to let any remaining gas fumes disappear before you continue.

2. Access the Pilot: Find the access panel near the bottom of your water heater, where you’ll see the pilot. You might have to remove some screws or a cover to get to it.

3. Inspect for Debris: Check for dirt, dust, or debris around the pilot area. Use a can of compressed air or a soft brush to clean it carefully. This debris can sometimes prevent the pilot from lighting.

4. Relight the Pilot: 

Here are the steps to relight the pilot following your water heater’s manual:

  • Turn the gas control knob to the “Pilot” position.
  • Use a long lighter or match to light the pilot flame.
  • Hold the knob down for about a minute.
  • Release the knob slowly.
  • The pilot flame should stay lit.

5. Check the Flame: Keep the flame steady and blue once the pilot is lit. If it’s flickering or yellow, it may indicate a gas flow issue. In this case, you should call a professional technician to inspect and repair the gas supply.

6. Replace the Cover: After the pilot is lit and working correctly, place the access panel or cover back and secure it.

7. Turn On the Gas and Power: Turn the gas supply back on and restore power to the water heater.

8. Monitor for Status Light: Wait a little while and check if the status light on your water heater is now blinking as it should. If the status light flashes, your pilot issue has been resolved.

03. Insufficient Power Supply

Your water heater relies on electrical power for its operation. If it’s not getting sufficient capacity, the status light won’t blink, leaving you with a no status light issue.


If your water heater isn’t getting enough electrical power, causing the status light not to blink, follow these steps to address the issue:

1. Check the Power Source: Consider moving some appliances to different circuits to reduce demand.

2. Inspect the Circuit Breaker: Go to your electrical panel or circuit breaker box and check if the circuit breaker that controls your water heater is in the “ON” position. If it’s tripped, reset it by switching it to the “OFF” position and then back to the “ON” position.

3. Examine the Outlet: If your water heater connects to an electrical outlet, test it with another device. If the outlet is faulty, consult an electrician to repair or replace it.

4. Voltage Test: If you have a voltage tester, you can use it to confirm that the water heater receives the correct voltage. Consult your water heater’s manual for the recommended voltage level.

5. Extension Cords and Power Strips: If your water heater is connected using an extension cord or power strip, make sure these are in good condition and capable of handling the heater’s power requirements. It’s often best to connect the heater directly to a dedicated outlet.

6. Overloaded Circuit: If your water heater’s circuit is on and shared with many other appliances and devices, it can become overloaded. Think about moving some devices to different circuits to lessen the demand.

7. Consult a Professional: If you’ve checked all the above steps and your water heater still needs to receive more power or are unsure about any electrical work. Getting assistance from a certified electrician to figure out and fix the power supply problem is a good idea.

04. Igniter Wire Issues

Igniter wire problems can hinder your water heater from igniting, resulting in a non-blinking status light.


If your water heater is experiencing issues with the igniter wire, which can prevent it from igniting and lead to a non-blinking status light, follow these steps to address the problem:

1. Safety First: Before attempting any repairs, turn off the gas supply to your water heater and switch off the power to the heater for safety reasons.

2. Access the Igniter Assembly: Locate the igniter assembly, typically near your water heater’s burner area. You may need to remove a cover or access panel to reach it.

3. Inspect for Damage: Carefully inspect the igniter wire for any visible damage, such as fraying, corrosion, or loose connections. Replace it if you see a problem.

4. Clean the Igniter: Accumulating dirt or debris may require servicing the igniter.

 Use a soft brush or compressed air to clean the igniter carefully.

5. Check the Wiring: Ensure that all the wires connected to the igniter are secure and not loose or disconnected.

6. Test the Igniter: Following the manufacturer’s instructions, test the igniter to see if it sparks or glows as it should when attempting to ignite the burner. Suppose it doesn’t consider replacing it.

7. Replace the Igniter: If the igniter is damaged or fails the testing, consider replacing it with a new one. Make sure to follow the manufacturer’s guidelines for the correct replacement part.

8. Reassemble and Restore Power: Put back any covers or access panels you removed to access the igniter assembly. Then, turn the gas supply back on and switch the power to the water heater.

9. Monitor the Status Light: Wait a while and check if the status light on your water heater is now blinking as it should. The igniter wire issue has been resolved if the status light is on or blinking,
