Monessen 26D0809 Gas Fireplace Thermopile Thermogenerator

It works! It was a little difficult to install in my situation. I have an older Monessen unit about 24 years old, but it worked well. Hopefully it will last.

Perfect fit for my Majestic Fireplace Model NVBR42RN Thermopile replacement.

We were uncertain if this would work in our 30+ yr old fireplace, but it was easy to install and worked perfectly.

Ordered in late Sept of 2023, as of January 2024, approximately 3 months later, the pilot light is going out. I am able to relight it and it functions for about 2 days. I will reorder this and hope it lasts longer this time.

After much diagnosing of my suddenly flameless gas fireplace, I determined the thermopile was the likely culprit (low voltage). After trying to salvage my OEM one I finally gave in and decided on this particular replacement since from the pictures it looked mostly identical and it cost about $80 less than I could find anywhere else. It IS a slightly wider diameter than the original, which I remedied by using a Dremel to enlarge the opening slightly (sandpaper and a dowel/pencil would also work for such a small adjustment), and once installed I was back in business. Fireplace is working fine again for now (don't forget to maintain your pilot lights and vents, people!) so the only concern is the long-term durability, but consider me pleased with the product as it stands. May buy another just to have handy to avoid downtime down the road.

Dropped by a local Fireplace Shop with old Thermopile in hand. What they had was 3 times the price. Wiring was too long and not protected with the metal shielding that the one I purchased from Amazon comes with. I got next day delivery and it was the perfect replacement.

Fast shipping, easy to install and a good value.

Easy installation for great price.
