@@jeremiahlawson2725 that's quite possible, but you should first check the air filter, make sure its not clogged, and make sure the exhaust fan is turning on when the heater is on, if all that checks out, then I would check the ignitor..

Thank tou for the info after check the video i fix the navien ncb240 Error 003 ,i was cleaningthe filters and shut down everything and after finish I turned everything on BUT I FORGOT TO TURN THE GAS ON LOL 😂
Hello, great video. I have a naviam nr210a. This unit keeps blowing the two 5 amp fuses. This the AC line coming in fused at 5 amps ( hot and neutral) I flushed system, cleaned intake filter. But it keeps blowing the fuses. Any suggestions will be greatly appreciated! Thank you
Hi, sorry to hear you're having that issue, it sounds to me like the unit is experiencing some sort of short, either at power supply lines or a component, this can sometimes be obvious to recognize with noticeable burn signs in wires or a component, or the total opposite where everything looks just fine, in that case certain tests would need to conducted to determine the cause of the problem. If you're not experienced working with electricity, my best advice is to suggest you call in a professional technician.
@@thediyyardie7192 THANK YOU FOR YOUR REPLY. FYI: ONCE I REPLACED THE TWO 5 AMP FUSES AT THE AC LINE COMING IN, THEN TURN THE UNIT ON. THE UNIT STAYS ON, BUT AS SOON AS I OPEN A FAUCET TO LET WATER RUN, THAT IS WHEN FUSES GET BLOWN AFTER A FEW SECONDS. THERE IS NO BURN SIGNS ANYWHERE. THX
Great video! Question for you…Would u know why my heater won’t turn on? There’s no display on circuit board when turned on. Is there a reset button somewhere? Model NR240
@peterhawth, there is a reset procedure, but the unit needs to be on in order to perform it, it sounds as though you have a power supply issue, a bad or shorted connection, a tripped breaker or worst case a burnt out pc board, try confirming the power supply first, it no issue there I suggest contacting Navien customer service, you can usually get a tech to walk you through a few trouble shooting steps, and possibly send you out a replacement part depending on the year of your unit...good luck with that..
To answer your question no, these units have what's called a flow sensor that detects when the hot water tap is turned on and thus kicks the unit on. The only other reasons I can think of that would cause this could be, a leak some somewhere in your hot water line or faucet , which would be most likely noticeable, a faulty flow sensor, or if your unit is connected to your home heating system, which is possible depending on the type or set up you have.
youve probably got the problem figured out already, but it can be normal for your heater to run intermittently if its been set up for any kind of recirculation. the heater will take a temperature sample about every 30 minutes ( time setting can be changed) and if it senses a drop in the hot water outlet temperature it will kick on trying to reheat the water already in your hot water lines.
I changed one on my home do they intend to wear out with in a year or so? I’m having that same code. I serviced it checked all filters and trap, flushed system with 2 gallons of white vinegar descaling the unit. It turned on for about a minute then shut off. Going to check the flame rod again and see. Thanks!
Hey Angel, it is not supposed to burn out within a year, but anything is possible, somme parts have defects and therefore don't last as long as some others do, best to check it and make sure it is good, at least to confirm if that's the issue or not, good luck with that...
I had it off last night went to turn it on and it turned on but the code now says 046E which is the the High Limit Switch. I ordered it waiting to come in on Thursday to install it myself. Hopefully that makes the system work fine again🙏🏽 Thanks for getting back!
@KluxBuster, it wouldn't hurt to try, explain to them what happened, depending on the age of your system, they may cover it. if not then you can always take care of it yourself..
Great video. Do you know how to display the date and time of the last error code? The newer Navs I can can, but I can't figure out how to do it on these older models.
Thanks much for the compliments on my video, not sure how old the model you're referring to is, or if it has that capability, but to get to that info I use the mode button to find code history, arrow down to code history and select, once selected it should show date and time of error code..Hope this helps..
@@Honeyman76 depending on what model unit you have, the screen will turn red when an error code is tripped. at that point selecting error code history will show date and time.. other than that I would suggest trying Navien customer service, let them know what you're trying to do, a tech can usually walk you through it.. good luck with that, and you're welcome..
@@thediyyardie7192 it turns out after I spoke to Navien, the best they offer on the older Navs is 1 to 9 on error history. There is a second number which is hours, but the Nav Technician advised me that it is not accurate.

@@Honeyman76 were you able to determine any idea of a date and time with the info you got from the Navien tech? even though he said it may not be accurate...
Yardie, I have a navien boiler ch-180 for 10 years . I never had any problems until now. I am getting domestic hot water but very, very Luke warm water to the radiator. Any suggestions will help. (Yard man also) . Thanks.
@@ncurtis14 ok sounds good, make sure the temperature on the unit is at the recommended setting, it may have been turned down accidentally.. it could also be an issue with the flow pump, check to make sure that it is operating properly, but the best check to perform would be to use a thermometer, a digital type would work best, you need to check the temperature in three places, with the heat on, at the supply pipe from water heater to radiators, at inlet pipe on radiators, and at the outlet pipes, if temperature is 65 degrees going into radiator, it should about 55 out or a little less coming out. this can also help you to determine where temp loss/blocage issue is located.. keep in touch, let me know what you find..
Where is the flow pump? I am going to get a thermometer and do the tests. Also I noticed that the boiler runs louder when using the domestic water and quiet when the heat is on. Thanks again for your help.
@@ncurtis14 there are actually two pumps in the system, one built inside the unit called the prime pump, and the main pump on the outlet pipe leading to the radiators, the correct name is the curculator pump.. also visually inspect PC board for any sign of burn, a bad board will also prevent the unit from reaching the proper operating temperature.. and you're you're welcome Sah..
I got the same problem and I replaced it with a new ignition, but after one day a new ignition be come dirty again. why, I don't know, you can explain to me the reasons, thanks
Are you saying the ignitor accumulated heavy soot after a day? if yes, make sure the ventilation system is operating properly, check filter to make sure its not clogged, you should also make sure the vent fan runs whenever the flame is on, sounds as though its getting more gas than air.. possible gas regulator issue also..
Hey Robert, yes you do need a regulator in the line, I would suggest get this done to the recommended code specs of the area you live though, unless this is for a RV or cabin, but yes you will still need to use a regulator in any case..
I have ch240 model, with the same error e003 code, i have changed pcb board, ignitor, it ignite runs fine for about 3 to 5 minutes then just shuts down, and throws error code, without trying to ignite. Help please
there are a number of things that can cause that issue, you already eliminated two, others include restricted air intake\filter, you should also listen to make sure ventilation fan kicks on during operation, or some other restriction to the ventilation, or an issue with gas pressure or regulator.
Hey Frankie, have you checked your intake air filter to make sure its clear of any blockages, and also what happens when you turn on the hot water, does the burner in the unit fire up any at all? you can look trough the sight glass while having someone turn on a hot water pipe, if it fires up and cuts right back off, it could be a issue with the gas supply to the unit, a faulty ignition module, blocked exhaust vent, or a number of other issues. try contacting Navien customer service if none of these seem to be the issue, they will actually walk you trough the trouble shooting process.. good luck, keep in touch, let me know how it goes...
To reset a Navien tankless water heater stuck in standby mode, turn off the power to the unit at the circuit breaker, locate the reset button on the control panel (usually behind an access panel), press and hold the button for a few seconds, then turn the power back on and allow the unit to restart; if the issue persists, consult your user manual or contact Navien customer support
Hey there Keefyboy, that info is in the video at the end, I show the box it came in, it says code number, if you google it, several sites will pop up, I ordered it through amazon, but its up you were you want to get it from.
hey Hector, can you give me some more info, have you performed any work on the unit, did you check the sight glass to verify if the igniter glows at start up, and is it trowing any trouble codes?
