Troubleshooting Rheem Water Heater Pilot Light Issues
Addressing pilot light problems in your Rheem water heater is essential for maintaining a steady supply of hot water. This section will guide you through identifying pilot light issues, relighting the pilot light, and understanding the common reasons for pilot light failure.
Identifying Pilot Light Problems
Identifying pilot light problems is the first step in troubleshooting your Rheem water heater. Common signs of pilot light issues include:
- No hot water
- Pilot light not staying lit
- No blinking lights on the control panel
A Rheem water heater pilot light needs to be lit manually using the piezo ignitor striker built into the water heater (1-Tom-Plumber). If the gas supply has been shut off or the pilot light is out, your water heater will not produce hot water.
Relighting the Pilot Light
Relighting the pilot light on your Rheem water heater is a straightforward process. Here’s a step-by-step guide:
- Turn the Gas Control Knob to “Off”: Allow the gas to dissipate for about 5 minutes.
- Locate the Pilot Light Assembly: This is usually found at the bottom of the water heater.
- Hold the Gas Control Knob in the “Pilot” Position: Use a match or the piezo ignitor striker to ignite the pilot light.
- Hold the Knob for 30-60 Seconds: This ensures the thermocouple is heated and the pilot light stays lit.
- Turn the Knob to “On”: Once the pilot light is stable, turn the gas control knob to the “On” position.
If the pilot light does not stay lit, refer to our rheem water heater troubleshooting guide for additional steps.
Reasons for Pilot Light Failure
Several factors can cause the pilot light on your Rheem water heater to fail:
Worn-Out Thermocouple: A weak or worn-out thermocouple can prevent the pilot light from staying lit. If you notice that the pilot light goes out frequently, the thermocouple may need replacement (Hunker).
Bad Gas Control Module: Issues such as no blinking lights and the water heater not lighting can indicate a faulty gas control module. A hard reset may resolve the issue. This involves unplugging the power cord (for power vent models) or turning the gas controller knob to the “off” position for 60 seconds before relighting the heater (JustAnswer).
Interrupted Gas Supply: Ensure that the gas supply to the water heater is not shut off. If the gas supply is interrupted, the pilot light will not ignite.
Blockages in the Pilot Tube: Dust or debris in the pilot tube can obstruct the flow of gas, preventing the pilot light from staying lit.
| Common Pilot Light Issues | Possible Solutions |
|---|---|
| Worn-Out Thermocouple | Replace the thermocouple |
| Bad Gas Control Module | Hard reset or replace the gas controller |
| Interrupted Gas Supply | Ensure gas supply is on |
| Blockages in Pilot Tube | Clean the pilot tube |

I thought Derek was polite. Courteous knew what he was doing. Got my furnace fixed in one day. I was very appreciative and because of his service I will now only use you guys going forward. He’s a great technician.
I'm always impressed when a service provider takes the time to educate me about the product I bought. Eddie explained the protocols for maintaining my mini-splits
, provided me with the knowledge that he brought to the inspection and showed me how to improve the longevity of the product. In the process he convinced me to extend my service.
Good job -
Eric, our Sanford tech, did wonderful as always. maintaining our beast of a heating system takes skill. He is prompt and kind gets the maintenance taken care of quickly. He doesn’t mind the annoying dogs or the beam that you have to duck under going up and down stairs.
They check in the day before coming and Eric texts when on the way. He is always on time. We have been very happy with the work and the professionalism.
This was my first time using Sanford. Derek was amazing. He diagnosed the problem quickly, showed me the problem, and then quoted me a price which was very reasonable. He had the part on the truck and had the problem fixed within a half hour. From the person I made the appointment with, Irish, to the dispatcher I spoke with for an estimated time of arrival, to Derek, my experience was nothing but positive. I had such a great experience that I will always use Sanford for my heating, cooling, and plumbing needs. Highly recommended!
After Sanford did such an impressive job installing our new Bosch furnace last winter, it was a no brainer as to who we wanted to add a central air conditioner to our house.
They gave us two options and we chose to go with a heat pump. Jason and his team did an incredible job installing the system in just a single day. The quality of their workmanship is second to none and he couldn’t be a nicer person to work with.
Another great job by Sanford !
We had Brian B come to our home to conduct a follow up visit to evaluate our Carrier AC that was installed in February. Just like the three-man crew who did the installation, Brian B did an outstanding job of making sure that everything was working just fine. He answered all our questions and made sure we were confident that our AC would be working fine this summer. Great job.
Extremely happy with the service I received. Mike did an excellent job of servicing my HVAC system. He was very efficient, knowledgeable and took the time to answer all my questions. Also, the office personnel were very helpful and responsive to all my requests and questions regarding scheduling and pricing. I will be using them again and would highly recommend Mike.
Excellent service. Arrived on time. Asked me questions to diagnose any possible issues. Explained several things I did not know about my system.
Eric was very pleasant & thoroughly cleaned & diagnosed my system. Every Sanford employee with whom I have had dealings has been pleasant, attentive, and professional. A friend recommended Sanford to me & I recommend them to you as well. I have been very happy with my equipment & service & know I can contact them anytime with questions & concerns & they will respond in a timely manner. Thank you Eric!
Our tech was great! He was respectful of the space (and rolled with the chaos of small kiddos running around like goons), knowledgeable, and efficient. We’ve used Sanford for years and will continue to do so.
Kyle G. from Sanford was awesome and super respectful. They installed furnace and AC system. He explained everything without being condescending, helped set up the wireless system, checked it and his team cleaned up everything after the job. My standards are pretty high and Kyle not only met them, he exceeded them. Thank you.
