750mv Thermocouple for Heat Glo Heatilator,Fireplace Thermopile Replacement Fireplace&Stove Accessories for Fire Gas Stoves Heat&Glo Gas Stoves Oven Water Heater&Frying Furnace (24", Aluminum)

I've tried several of these. They all work for a while, then they stop. To fix that you need to clean out the two little air holes on the pilot tube. Then you get a hotter pilot flame, then they work right again. Plus I made mine really good: I just added a second one, wired it in series with the original one. I mounted it coming from the other side, and held it in place with some aluminum wire, which is really easy to do because aluminum wire is easy to use. So I get the volts off of two of them, it works super well, and then they last for a long time, as long as you clean the air holes and the pilot tube blowing some canned air or exhaust air or sucking it out even with the vacuum cleaner. You can see that the pilot then burns stronger, which is hotter, which gives you more volts to open the gas valve. Look at YouTube videos on how to clean gas fireplace, or the manual that came with your device.

My handyman had no issues installing it and I now have my fireplace back!

UPDATE: seller reached out and offered replacement. Replacement received and works. Very appreciated. A seller that stands behind their product. Thanks!ORIGINAL REVIEW: The good was the fast delivery: Got it in 1 day. The bad is it doesn't work. Wouldn't get past 300mV. Held pilot ignitor for 5 minutes and wouldnt activate valve on my gas log set. Otherwise, I would like a replacement.

Worked perfectly my Heat Glo unit. I'm about a year out at this time, and it has performed without issue. Saved me quite a bit on a repair bill.

This was an exact replacement for the thermocouple is my daughter's gas fireplace.We changed it out last year, and it's still going strong.

This part fit my gas logs fine. It lasted one winter of use and then quit. You can see the hole that the pilot light burned in it. Definitely not a quality part.
