    Unfortunately this is a semi-consumable item that needs to be replaced every few years. The tip does not seem to be made of a durable material, so it'll wear out a bit earlier. It's cheap and does it's job.

    I keep an extra one on the wall now for my old garage furnace. This replacement worked like a charm.

    5.0 out of 5 stars Works Better Than New!
    Reviewed in the United States on October 24, 2024
    Verified Purchase
    My Empire RH-35-7 heater was always difficult to light, right from the factory. I had to hold down the "pilot" dial at least 1 minute, sometimes 2, before the pilot would "catch" and stay lit. After replacing the thermocouple with this one, it would "catch" after about 10 seconds! I measured the old thermocouple with a voltmeter before I installed this one. It would take about 45 seconds to reach 10 millivolts, and wouldn't go higher than 20 after two minutes. (It's supposed to generate 30 millivolts). Granted, it was pretty much worn out; but If you're having similar issues, don't mess around - - - about 5 minutes of work will save you a lot of aggravation. Wish I had done it a few years ago!

    My local plumbing supply store was closed and I was forced to buy one from HD. It worked but I had to retro fit the fittings from the original resideo thermo coupler. I ordered extra resideo couplers to keep my plumbing bag.
