awesome 3yrs later and your video is still helping others. inflation got the part at $26 buck but better than a service call. tell the kid at the end that i hit the like button.

Error code 11 started flashing last night..I always go to KZfaq first for everything that’s broke to see if it’s fixable at my level. Looks like I’ll be buying a $22 part and DYI! Thanks for such a helpful video

This is the EXACT problem I was having and I had no clue where the ignitor was even located. Other sites tell you to check it, but not how to check it or even where to find it. Great video. Thanks for posting it.

Great video. My plumber wanted to run hundreds of dollars of "tests" to diagnose my Rheem tankless. I said no thanks and ordered the igniter coil replacement. This fixed it.

THANK YOU! This worked. I had someone check the error code and they quoted me $900 to fix, but recommended replacement approx. $1400. Should have come to KZfaq first. Easy to get the part from Amazon and got it done really easy. Thanks, again!

This was an exact replacement for the old one that lasted about 10 years. kzfaq.infoUgkx7yWIKcrbA9KMHkGSfcgxW2lsjHT6B8Sh The top of my mitigation tube by my roofline was just a 90 elbow which allowed too much debris to fall down into the fan, eventually ruining it. Without this issue, I bet it would have kept running another 10 years. When I replaced this fan, I added an extra elbow joint so the top tube now it does a 180, which should solve that problem. The radon guys around here wanted to charge me a $300 diagnostic fee, then parts/labor (probably close to $600 total). I installed this all by myself in about an hour for the cost of the fan; it would probably be even easier/faster with two people. FYI the manufacturer's warranty greatly differs depending on whether you install it yourself (1 yr warranty) or have a licensed installer do it (10 yrs).

Lifesaver!! 🎉 thank you for this video! A plumber came out and looked at my water heater for 2 minutes (turned a valve on and off was his assessment) - then proceeded to tell us we needed a new unit and he could sell us one and install it for $2,500. Didn’t sit well with me! Called the manufacturer and they said for my issue it was usually the igniter coil and parts were still covered under warranty so they shipped one to me for free. Found this video and installed it myself in 5 minutes. Hot water is back!! Saved me SOOOO much money. Thank you thank you thank you!!!! 🤗

This was spot on! Thank you so much Prasad for sharing your experience. Your video was straight to the point. I bought the part of Amazon yesterday (paid more but got it today, and bought one from Rheem as a spare for $22). I appreciate you!

Just did this exact repair and thank you!!!!! Saved hundreds of dollars for a $28 part. Took 5 mins or less to change the part out. Awesome.

Thank you so much! I’m a good handyman, but knew nothing about the workings of a tankless water heater. Your video convinced me I could avoid a $625 plumbing labor charge and do the job myself. Everything worked perfectly!

Sir, thank you for this valuable video. I followed your instructions, ordered the part for $23, paid $16 for next day shipping and we’re now back in business. Literally took less than 5 minutes to replace the part and fire it back up. So thank you again for sharing your insights and saving me time and money!

Thank you! Spot on, picked up the part from a local plumbing supply company, installed in less than 20-min, hot water is restored. Great video, you have a new follower. My igniter failed after 2 years of service. I recently replaced my tankless heater after the winter storm in Texas.

Thanks! You saved me over a $1,000 as no one wanted to fix it, they all said they only replace the whole unit. I had a hard time finding the part but it was an easy fast fix once I did, thanks to your video!

Thank you so much. Your video was clear and easy to follow. It saved us a service call and much more. This was our problem, so happy to have hot water again!

Thank you... I fixed it exactly as your video shows and saved a minimum of $300+... and have HOT water today instead of 1-3 days later... God Bless You... Austin, TX

This is an excellent video! You showed the same errors and sounds I am experiencing. Everything is explained very clearly. I just ordered my part and I am confident that I can change this myself. Verygood video. thank you!

Thank you Prasad! I watched your video and ordered the part, $20 bucks later I had the issue resolved in 10 minutes!

I just had this replaced with a freezing damage unit's part. Look like a common issue. This unit was installed in 2021 after the Texas grand freezing incident. Will call Rheem for replacement part as mine is still in warranty. Thank you. Maybe we are in the same community.

Thanks. Changing the igniter fixed my problem. You even mentioned Supply House in the video so I knew where to buy the part.

KZfaq for the win! $20 fix and DIY 👏🏼 thanks for sharing

Great video I just followed this step by step and it worked. No more cold showers

Thanks! Your video helped be fix our issue and replace the ignitor coil. Thanks for listing model #s and parts #s too.

Victory ! Enjoying a super hot bath after messing with error code 11... My unit is very gas pressure sensitive (nearly 10 year old unit). I use an adjustable gas pressure regulator with gauge. It has a very small window to run happy (barely reading just under 1psi). Anything under or over it won't stay lit & errors out. I loosen the gas bleed screw under the unit till it drops pressure. You can hear the gas hissing so I know it has supply. Screw it back in & find the sweet spot, a Very low pressure. This time I needed to unplug power cord & the ignition system two wires, wait a 10 min. Plus it all back in an boom = Fire !

This was a great video! I swapped it out in about 5 minutes…..the instructions were spot on. Thanks!

Many plumbers want to sell a whole new unit. Faster and easier. Great video

It took longer to trip the breaker, get a screwdriver, remove and replace the front panel and put my tools away than to replace the part. Super easy! Thanks! I suggest you replace both the igniter and the coil. Parts are so cheap, why not? Wife says I'm now a DIY plumbing hero. :-)

Wanted to say thanks! This was exactly the issue I had. I was able to fix it for $15.

prasad. can't thank you enough!!! this was exactly my problem. $30 later, part got here next day from amazon, ITS FIXED. so easy and its all because of you and your video. I was dreading all the things a plumber would say and charge for such a simple fix. thanks again!!

Thank you! I followed your instruction and fixed my tankless.

Very nice in staten island plumber was two trip one to tell you error, then wait for parts come, then he will come install another trip +installation +part cost minimum $350 and I did it in by parts only $30.00

Thank you very much for the video! I just had exactly same problem and the video is so helpful to fix the problem!

Thank you for a thorough explanation and walkthrough!

This was a great video. Simple and easy to follow. Appreciate you!

This fixed my problem, thank you for saving me lots of time and money!!!!

Great video, Thank you. The outlet cord problem can be solved with a 90 Degree cord end, and marking the outlet box with panel and breaker Number also helps for home owners or next tech to easily ID the Circuit... ; )

this is so helping thank you superb

Worked perfectly. Thank you

Life saver. Thank you for your video

Thank you!!! This video is a huge win

you the mannnn, saved me money and fix it my selfffff

Thanks, this helped me fix my heater

Thanks for posting!

You da man. Excellent video, thank you!

Thanks man got my problem fixed for only 25$

Do you happen to know about model number RMTG-74PVN-1? Error code 11. Found ignition part, but it seems the black wire goes to the back. Not sure if I can disconnect it that way or pull that apart?

Any idea how to remove the electrode? The little white piece with the hook that you attached the adapter to

Thank you so much!

Also, check to make sure your intake vent on the outside of your house is not blocked. No air, no flame...

I have a Richmond tankless water heater M#(RMTG70DVLN-1) do they share the same parts because I can’t find the Igniter Coil for mine online?

Thank you sir!

We’ll done bhai sab. Exactly what I needed.

This worked perfectly for me - thank you!!!

I have a riddle for you. My issue was the same as in your video. I changed the igniter coil but still having the same issue. The unit was working fine until my LP gas man changed the tanks. Could that have something to do with my error 11v

I changed my igniter coil and now I get code 13. Any Idea what could be the issue here?

Spot on thank you

I could save $400 if I watch your video before I call a plumber as the customer service suggested.

Thanks!

Good morning.. my fan isnt come on do that mean I'm not getting no water flow

appears mine is broke right out of the box. getting 120vac in but no heat on the probe.

That was great thanks, That is probably the most wrong space for that outlet though.

Good video, but I found out what was wrong with my Rannai code 11 and why the coil and unit always turned off. The electrical unit was wired to my dryer and it was getting to much voltage onto it. The professional checked his electric meter and all 4 lights where on when it should have been 2 lights. Hope this helps someone with the same issue as mine.

i have a rheem 18 and i have 3 ignitions, whats the go

Just saw video days ago went and purchase igniter replaced and the symptoms are the same don't know what to do now

Had the same problem on my rinnai after replacing the heat exchanger, all I had to do is unplug the harness to the igniter and plug it back then it worked. I think moisture or a little water gets on the connections

I can clearly see my igniter is firing every time. But I'm still getting code 11. Any ideas?

Fixed mine just right now with about $25 dollars.

excellent

I changed that, and now the controller doesn't power on. Any suggestions?

How about a rtg74ns2 direct vent ?

Very good video. I'm dealing with that issue now. Is this a common issue with these water heaters? Because of the availability of the igniter, do you suggest keeping a spare? Thank you

You only need to turn the power off, not the water supply or drain the unit. Turn off the gas to be safe is OK, but again, not necessary.

I am in Dallas, can you help me?

I just don’t know how he determined that’s what it was. He mentioned about the gas and checking your stove etc but what told him the coil pack was what was the issue.

Having the same issue on a brand new unit in brand new home

code error 113and 112 on rheem tankless hot water heater

Check the regulator first everybody

I've been trolling YT the past 24 hours, "In Search Of" (Leonard Nimoy) error code 11s. Here we go. Error Code 11 on NRC111DV 199 BTU. You're never going to guess what the problem was! Got a call from the tenant (this is a rental). Was proactive and ordered Ignitor and Ignition Plug. Turns out, the next-door neighbor moved out. Gas company showed up and turned off the gas meter to my house (no notice), not the house they were supposed to (neighbor). 24 hours later, multiple troubleshooting, cuss words, discovered the root problem. Point being, check the not-so-obvious things first. Damn it. Do I want to mess with small claims court? Maybe, maybe.

Damn, replaced mine and it didn't fix the problem.

Or your gas services have been cut off... Pay your gas bill or you'll get an 11 error...🤪😉

another Indian plumber

dond dell me whad do do

You went strait to changing parts. This video make you look good but no diagnostic info. You have no clue to what created the problem. Show Boat!!!!!!
