Just what my maytag hotwater Heater with a honeywell gas valve needed to get my hot water working.

2nd time it went out, reset ist time had to replace the 2nd time. why do these go out so often?

Had to replace this sensor on a Rheem gas water heater at 3 years, 2 months. Could not buy locally. Seems to subject to frequent/premature failure from what I see on the web. I dinged Rheem for supplying a problematic device that will leave you without hot water unexpectedly. If you have one on your water heater, keep a spare handy.

I have a Rheem Performance Platinum water heater that uses this part. I had the 7 blink notice more and more often for 2-3 months, and finally the reset procedure didn't work, and the blinks changed to 8 blinks followed by one blink. The error codes printed on the water heater (and NOT in the manual) showed the eight-one notice to mean faulty FVS device. So I ordered this part, but in the meantime I needed to shower. I Googled the problem and found two potential solutions. You have to remove the faulty sensor from the heater by unplugging the two wires on the back. The first solution (not) was to put the two FVS leads in a half-full cereal bowl of water, then doing a reset, and it made the pilot ignite, but 20 seconds later it went out--not a viable solution. The second temporary fix (that worked) was to remove the sensor from its white plastic cuff housing to allow access to the actual terminals. This requires immobilizing the core of the sensor with a vise or a pair of vise grip pliers and using a screwdriver to break off the plastic cuff around it and the cover that has the four holes, which is held by glue. (Obviously, this disables it for future long-term use.). Then clean off the black stuff from the two rectangular terminals. The next step may sound a bit looney, but it works. Take a pencil and scribble on the plastic between the two terminals. Then plug the sensor back into the water heater harness. Turn the heater off, put the thermostat on low, unplug the heater, plug it back in, turn the switch on, use a screwdriver to rotate the thermostat from lowest to highest setting 7 times. You'll hear the pilot light come on, and it will stay on. Hello, warm shower!Why they sell this water heater without notifying the purchaser of this COMMON, almost predictable failure is beyond me. God forbid they would include a spare FVS with it, or maybe even provide an explanation in the manual in ordinary English! It may be a revenue generator for the plumber who sells the water heater, a reward for selling Rheem. Internet to the consumer's rescue!

Good

Cup of H2O is a great short term fix while your sensor is on order.

Works great

Fixed our issue, easy enough repair after Google searches. We are finishing our basement and have painted trim work. The sprayed enamel paint tripped the Flammable Vapor Sensor on our AO Smith water heater. No reset methodology would work (I even pulled the sensor and moved it do a different part of the house overnight). Ordered this replacement part on a Saturday and had it Monday before noon. Part did what it was supposed to, water heater is up and running again. It's an easy replacement and certainly a do it yourself vs. calling a repair person who will likely charge you $150 just for showing up on a $25 part.The downside of these are - you need the one you need, there aren't really “options”. If yours dies you need a new one. They're finicky, as I said mine wouldn't reset and I read a lot of people having issues with these and their durability / reliability. It's almost worth having a spare on hand (though if you google right you can find some temporary bypass solutions). $23 is the cheapest I could find this part which is really probably a $3 resistor at best. Crazy price for a cheap part, but it is what it is and this one does the job. Certainly don't need to pay $50-$70 for other versions of this.

This item fit in perfectly and worked, but is a little pricey for what it is.

Worked perfect for me

OK

Water heater kept saying it was locked out by the FVIR. After a while I could not reset it.. This part fixed that.

Works perfect

perfect

Didn't work. Not sure if it was a faulty part or in all probability a faulty Workman - - ME!
