US Merchant Thermocouple 2304885 Dyna Glo 40-150K btu LP 1130/1474 by Fixitshop

Good part, worked well

Purchased this to make sure a propane gas heater was working good before winter. This is a backup unit for when the electricity fails. Works, but so far have not needed it to be there. But at least I am ready.

Works great on my propane heater

Wire lead is too short. Spliced new wire. Heater fired up. It works.

My DynaGlo Pro variable 30,000 to 60,000 BTU fire canon suddenly wouldn't stay lighted, so right away I suspected the thermocouple.Unless I did this wrong, installation of this simple 1-screw 2-wire part involves pretty substantial disassembly of the heater.The removal of the blower motor & fan is necessary. To get to two of the motor mount screws, the gray base must be removed. To remove the gray base (4 screws), the gas lines must be disconnected from the valve (2 flare nut fittings). There are a few zip ties that must be clipped to separate the thermocouple wires from the rest of the bundle.The burner can itself, nor the gas outlet inside the can, needs to be touched.Also worth noting, during reassembly, check all wires for clearance from the fan blades, and zip tie as necessary. There's plenty of room in here, but it's very easy to overlook this detail and have the blades hit a wire once powered up.In any case, the part itself is identical to the OE part, which is refreshing. I've done oven repairs where the thermocouple is "generic" and the wire length or fitting are different and require adaptation. This piece is a like-for-like replacement.

All good

Mine was missing the pictured bracketI removed the old one and reinstalled it using that, but that was not the proper way to do it, it is not easy to remove that bracket, and was not easy to make it work, it added quite a lot of time onto a job that already requires a lot of disassembly. I had to have it working for the weekend coming up so I had no choice but to make it workFor all that, it DOES work, it IS cheap, and I think if the QC was a little better and the items came as pictured it is a great dealI will probably not be able to rate the life span as I don't use this heater much at all

I bought a "broken" forced air heater and it would not stay lit. A little research suggested this was the issue. So after about ten dollars it works great now! I will say that it was a bit time consuming to switch out, but that was because of the design of the heater, no fault of the product.

Everything fit. Length was fine. I reused my old bracket but, if the thermocouple doesn't reach as far as the original, the new bracket can be moved to fit. Thermocouple works fine.

This did the job as as suggested. I was holding the igniter in for what seemed like forever, seemed like a few minutes so this season it was time to fix it. Now it's 5 seconds & the flame stays on! Pic attached of old vs new, also where it sits in the canister. If yours is a 30-60K Home Depot type Dyno-Glo, & you're curious about how to attack this repair, this is what I figured out. Go at it from the fan/motor end. There's 1 of 4 screws that's really awkwardly placed, & you may have to detach the bottom assembly that houses the electrical & wiggle that around until you can get at that last screw. Unhook all the electrical from the motor/fan & once you can pull that out of the way you have access to change out the Thermocouple fairly easily. I couldn't find any videos online to help me so hopefully this points you in the right direction! Cheers....
