OEM/fixed a low flow no heat issue for Navien NPE 240A(NG) series.
Came in a Navien OEM plastic wrap, looks and feels OEM so I trust it.Old flow sensor's turbine fins compared to the new one were totally seized, which is causing it to not sense low flow like faucets (but if I open up the relief valve or hot water hose bib to induce HIGH flow, the burner will come on). New part has fixed the issue. Recommend taking the time to replace the O-rings if possible. If the issue still happens my next recommendation would be to also replace the check-valve.for Navien NPE 240A(NG) series.

Exactly the part we were looking to purchase
It was so convenient to find the part and have it here so quickly. I also ordered an o ring pack for the parts I ultimately ordered. Everything was perfect!

Exact replacement
I have two Navien tankless water heaters. The one that gets the heaviest use has the kitchen, master bath, and basement bath on it, and is a recirculating "instant" water heater. It started acting "funny" with the water temperature jumping up and down from scalding to freezing. I diagnosed it was the flow sensor. I was glad to find the exact replacement at a reasonable price. I am a skilled DIYer and glad not to have to pay a tech hundreds of dollars to change this part out and get my water heater working again.

Buy somewhere else!!!
Got the part, looked new, installed it, the fit was right. Not sure why but it didn’t work unfortunately. Had to be without hot water longer. Hence the one star. Called a plumber who came and replaced the same exact part and it did work. Sending it back for refund.

Flow sensor fit perfectly.
Navein is easy to work on and this part was no exception. 8 years of hard water caused the inner turbine to quit spinning. New part removed one piece of the puzzle in getting the water heater back in line.

Works 50% of the time
I bought 2 of these to fix a problem with a Navien tankless water heater that was failing to heat water sporadically. One of these worked and one didn’t. I don’t know what the problem is with these sensors, but they fail eventually.

Defective product
I have now purchased two of these- both don’t work. First one didn’t work right away and the second failed on the third day after installing. Returning both and reordering - hopefully the third time will be the charm.
