Perfect fit for my Kozy Heat (Hussong) 761DV gas fireplace. Wall switch had ceased functioning. Thermopile tested low on MV output. After replacement, Voile! wall switch functioning again. Total time to replace: 1 hour with most of the time spent removing and then reinstalling the fireplace glass and logs. No idea on longevity of this replacement (original lasted 20+ years).

Lifesaver. Watched some Youtube videos and troubleshot my Cozy brand wall heater and determined that it was the Thermopile. I can't remember exactly, but I think the pilot light would stay on but the heater would not start. My old one was just under 230 millivolts or something which should have worked but I guess these are sensitive. It just worked. Plug and play. Phew. In a pinch you can try cleaning the old one with a dollar bill (anything coarser will remove the metal coating I guess?)

Exactly what I needed to fix a pilot that would not stay lit. Replaced 26 year old thermopile in Marco (discontinued manufacturer) fireplace. No original parts available. I did have to splice connector from the old thermopile but easy and just used some butt connectors. Work was a little tedious as fireplaces don't have a lot of room to work. But about an hour later all was running. Took millivolt measurements when done and all well within spec. Saved me a bunch of money by not having to get a service call or buy part at a local overpriced fireplace store.

Value priced, and when the thermothingy heated up the current was enough to wake up the electromagnet in my old gas fireplace. I heard it open, strong! Fixed my fireplace, I'd buy it again.

After replacement the fire stayed on. You can DIY, est 1 hr.

This thermopile is advertised and specified to produce 750 mV. My unit only produces a maximum of 575 mV.I tested it open circuit (under no load) with my stovetop flame fully engulfing the upper sensitive portion of the unit (much more flame than normally realized from the pilot light) so that the upper portion of the unit was glowing red hot. After about two minutes, the open circuit finally crept up to 575 mV, but would go no higher. I went ahead and installed it until I can get a fully working replacement, and it only intermittently operates the gas valve in my fireplace.FWIW, I have degrees in both Physics and Electrical Engineering, so there is a reasonable chance I know what I'm talking about when I say that the product I received is out of spec, and not by just a little. I won't be buying any MENSI product again, if I can avoid it.

I ordered this product online when i figured out that it was the problem with my gas fireplace. would not stay lit and would not fire up. Received very quickly in perfect condition, I installed it in about 30 minutes and fireplace fired up immediately and is still working great after a month or so. this product was a perfect replacement for the OEM. I saw a few competing products online and they were less money but I decided on this one even though it was a little higher price. it seemed to be the best quality and it is working great.

Got two. One for the downstairs fireplace and one spare for when the upstairs one needs replacing. Pain to install but that's the fireplace's fault, not the thermistor.Original ran for 16years. This one is on it's second year. No issue.

Installation of a thermopile is not for everyone. There are lots of YouTube videos available that show you the replacement procedure, and also check out the YT videos on how to test your existing thermopile before ordering a new one. This one was an exact replacement for the old Honeywell it replaced. Just be sure to order the correct model for your needs, and also pay attention to the wire/cable length
