Rinnai fan replacement and repair.

[@chplat]

Can I say, you are an amazing human being. I could not get a plumber to look at my extremely loud v1500 hot water system without saying just replace it. I took the fan off and took a large lizard and decent huntsman spider from the cage. Not a peep out of it anymore. Thank you so much.

[@cameronanderson8222]

Mike is the Man! Woke up this morning for a Saturday shower. Rinnai fan is going bonkers.... loud as hell. Thought I was going to have to buy a whole new one. Followed Mike's instructions. Gecko was still alive in the fan assembly (poor fella). Gently set him free in the yard. Tossed the fan back in. Operating normally. Took about 20 minutes. Thanks a bunch for the video and knowledge Mike!

[@davidhill1944]

Add my name to the lizard list! Many thanks for a straightforward easy to understand video without annoying music. I was able to get the lizard out and get up and running in very short order thanks to your video.

[@paultokarowski9646]

No Lizards but bark mulch !!! Thank you Mike for the excellent video regarding the combustion fan debug and replacement. I was seeing a code 61 (fan issue) on my R75 and after removing the fan from the housing I saw a 1" piece of bark mulch that was preventing the fan rotation. Took it out, re-assembled and boom, a hot shower after two day !! The inlet/outlet is right over a side shrub area that has mulch to control weeds, Thanks again.

[@fraserc1285]

Mike, your instructional video is excellent! My house has been renovated, and when they demolished a wall in the bathroom they literally threw much of the plater and lath into the wall. That cascaded down over time, and entered the Rinnai and got into the blower intake. I ran some electrical wire in this area, and even though I temporarily blocked the area above the vents some got in - and the unbalance was very loud! With your video I got the blower out, emptied the plaster, and it sounds new again!

[@MichaelCarsonNH]

Thanks for the great video. You showed me the magic two screws for getting the fan out. We've been getting a code 10 for awhile, and knew the fan needed to be cleaned out, just couldn't figure out how to remove the fan. Now that we have and cleaned it, running normal and quiet again. Thank you.

[@TheBuddylab]

Michael Carson I’m glad it helped. Mike

[@awesomesauce2935]

Thanks for the video! My water heater literally sounded like a jet flying through the house. I pulled out the motor, blew out the various stinkbug bits and pieces out and got it put back together in about 20 minutes. Now my water heater's quiet again!

[@ThatTanklessGuy]

Awesomesauce glad it helped. Mike

[@TheBuddylab]

Awesomesauce I’m glad it helped

[@boydbria]

Thank you! Saved me a service call. FYI on my indoor Rinnai 65 I had 4 screws on the fan. 3 on the inner part (which didn't come out) and 4 on the outside. The upper right screw was the one that was difficult to get back in, but I wrapped the little red 'tie' strap that was on it around the screw driver and managed to get it to not fall out every time :) . Without even knowing how to take this apart I had it all back together and not making any more noise in about 45 minutes by watching your video. Oh and the culprit? A darn lizard that wanted to take a ride on the magic spinning wheel of death!

[@TheBuddylab]

Brian Boyd we get tons lizards stuck in fans here in Florida, we even had two still alive when I removed the fans. I’m glad the video helped. Mike

[@boydbria]

@@TheBuddylab Thanks! Yep this is in the Tampa area...got those brown ones here all over the place. Unit survived 2 years without one, so that's good! But vent is on the roof (indoor unit)

[@kyeehart1545]

Very simple, straight forward video Mike; much appreciated! My heater was make a loud whirring noise just like others described. Followed you instructions, removed exhaust fan, and lo and behold... a lizard! Cleaned it up and reassembled, totally fixed now! Add my name to the list of people that owe you a cold beer, you're a life saver!!!

[@cmsgtgoose6334]

Thank you very much. My heater has been acting up for years and after watching this got the courage to address. Worked like a charm. Mine had those tricky wires you mentioned so I left them connected and worked around them. The fan was filled with lady bugs and pollen. Used a shop vac, compressed air, and a tiny screwdriver to clean up all the debris. Thanks again. - Erik

[@patrickchaplin2365]

G.B Stein said"silent gratitude isn't much use to anyone" - with that I say Thank you sir, saved me a costly service call.

[@ntxmike3705]

Thanks man! I followed your video and was able to fix the issues with my Rinnai tankless. It indeed was a moth in the fan and once removed it had no issues....

[@FrankMCaimi]

what a great video! Here in Florida lizards are the issue. vibration terrible until lizard body was removed

[@TheBuddylab]

Frank M. Caimi we get hundreds per year

[@LynnLary]

Thanks for posting your video. I had seen one other very similar, but it was not specific to my water heater model. I really appreciate that you covered both of the water heater models in your video. I was able to very carefully remove the wires and then pull out the fan and the dead bug. No more vibrations! One of the things I really liked in your video was how you made that little black line so that we knew exactly how to line things up when it was time to put things back together. Great tip. I also used my marker to draw on all of the wires that were clumped together to make sure that I got them all back the right way. That and a couple pictures to do a little before and after comparison. Again, thank you!

[@cherylaharper6603]

Thank you for your help. I have the Rinnai R75LS. I realized after watching the videos that the people who have been servicing it have never flushed it or taken anything out of it to clean it. 10 yrs of servicing. The fan was so full of bugs that I had to soak the housing to get the bug guts off of it. The heat exchanger was full also. Flushed it for 2 hrs. After putting it back together it was making load popping sounds, so I took the fan back off and realized that the rubber boot had been off the back side of it. Now it hums quietly like it did when new.

[@sofiasoto445]

Thank you! As it turns out; I had a seed from a maple tree (helicopter) stuck in my fan. I couldn't have fixed it without this video.

[@ofplon]

Thanks! After cleaning, I reinstalled my fan without seating it first, hanging only by the screws. Hell of a vibration! Now I know, thank you.

[@gregorybradt9386]

Hello, did the vibration sound anything like this? kzbin.info/www/bejne/a6DOi4R6pbaFj7M

[@99jeepxjguy97]

Thank you sir. I have a 2007 model R75 LSi (indoor). It was running great for 12 years, but suddenly today it started a horrible vibration. Haven't removed fan yet, but don't see evidence yet of wetness from leak. ( no gekkos here in Idaho ) ;) -EDIT - 18 minutes later. It was a MOUSE, and a big one, stuck in the squirrel cage! And still alive although quite dizzy! Like I said, no gekkos here! ha ha! All cleaned and back together now (an hour later) I will fabricate a screen tomorrow.

[@TheBuddylab]

Great to here your problem is fixed. Unfortunately I do not recommend a screen over the vent. It will block the exhaust and air intake. Mike

[@justinw9625]

Thanks for the info! Ours got noisy 3 days ago. Pulled the blower and it had a tree frog in it. Good as new now. Thanks!

[@MStrongPhoto]

Thanks for this great video. It’s definitely not obvious how the fan should be removed for cleaning from just opening the units cover.

[@fredg8199]

LOL! We are all journeyman plumbers here for sure! :)

[@BlindmanValley]

I have one for the books. I've been trying to cheap out . My first Rinnai started giving me 5 minutes of hot water then went cold - I thought it was Fubar . Bought a used one - installed and it worked for 3 weeks then popped a small hole in one of the exchanges tubes on the outside of the unit - so I bought another used one. Yesterday it shit the bed. it would want to start but would shut off and code 12. Pulled the fan and the squirrel cage was snapped off the shaft. I looked at unit 1 and the current unit ...same ..exact same fan. Pulled blower out of unit 1 - swapped with unit 2 and voila - it all fit..right up until i went to plug the 4 pin in....different sized! pins are just slightly wider. Soooo pulled the 4 pins out and figured theyd fit in the other plug - nope - to short. So put the wires back in old plug - plugged it into the blower - cut the red - black - yellow and white . cut the new and old ones and spliced ..its gonna work now ..nope .. its all correct..all in correct order ..So now I have 3 junk Rinnais ..Im going to line them all up outside and put about 600.00 worth of 306 rounds through them and buy a hot water tank. I guess i better ask the question...if the blower motors fit perfectly in another housing - has the same colour wires in the same order on the 4 pin plug in but the actual plug is different - if the wires are spliced in order - should it not work??

[@jeraldharriman6130]

EXCELLENT INSTRUCTIONS You cover every aspect and do it in a very logical easy to follow format. Took the fan off, easily found the two lizzards, extracted them, blew it out, put it back together, runs like a new machine. A question, any tips on how to keep the lizzards out of the machine, it was full of empty egg shells etc. We are trying to fend them off with screen over the exhaust pipe.

[@bryanhendricks3152]

Mike, thank you. It had several dead wasps in it.

[@tamishapatterson252]

Thank you so much for this video...you have saved me a service call fee😁 btw I had a gecko in my fan assembly 🤦🏽‍♀️ which is the reason my motor sounded like a construction zone

[@jenniferstinson7150]

Code 10 seems to be my trouble Mike. Not when I'm washing dishes or clothes, mind you. Always when I'm in the shower. Of course. Last year we took the fan off and found mud dauber wasps had built inside the fan and so I suppose that is the problem this time. Is there any way to prevent critters from getting in without interfering with the air flow and exhaust? I'm SO glad you are doing these videos! You do a great service to the public!

[@howardwang5516]

Jennifer Esss I have the same code... So it's the fan that needed to be clean out

[@ThatTanklessGuy]

Jennifer Esss Rinnai has no approved screen to go over the vent pipe, buy there’s after market screens you can buy. That is one of the big problems we have here in Florida. If the dirt doers got into the fan they are in the vent and burner. You will need a qualified service Tec to check that. Mike

Hey Mike. Thanks for all the excellent information on Rinnai tankless water heaters. I have a Rinnai RUR98iN which has the internal circulation pump. Ever since it was installed I never hear the internal circulation pump turning on and I don't get immediate hot water. It's setup with the crossover valve at the farthest sink in the house. I've checked the dip switches and they are properly setup for re-circulation using the crossover valve. Should I here the pump when it turns on? Any ideas what to check? Thanks..

I have the 2 zones direct since the home is under construction and there is no thermostats installed. On the pannel i do get a "0" and i belive the temp thats at 90 Read the manual and it looks like the there is no heat demand. Should i use the RS100 ?

Violent - BlockIndustryRecords once you get the thermostats in see if that helps. You will need to have relays to operate the plumbing like Taco two zone relay. E mail me with any other questions when the system is running. Mike

Have you checked to see if something in the house is bypassing like the washing machine or shower cartage?
