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.

I wasn't exactly sure what the issue was with my fireplace. The fireplace would work intermittently, but only after with a lot of manual intervention. Reading online, it appeared that the issue may be the Thermopile. I tested the voltage, it was clear that the voltage generated by the old Thermopile was weak and inconsistent. The replacement part arrived a week earlier than expected and was very easy to install. My fireplace now works perfectly! Very happy with the delivery, the product and the results.

My fireplace quit working. Pilot light was on but would not ignite when I flipped the switch. Installed the new thermocoupler and works perfectly again.

Easy to install now the gas fireplace ignites immediately very happy with my purchase.

Very glad to order online
