Hello, I ordered a new thermocouple for my gvr 50 100. The factory one appears to fuse soldered to a bracket, but this is missing off the replacement thermocouple. Did I get the wrong part?
Optional Information: Make : AO Smith Model : GVR 50100

Hi, I'm Douglas and I am here to help you resolve problems with your heating and cooling equipment.
hi doug
It shouldn't be fused... one moment while I look at something
The original unit has something soldered in between the Thermocouple end and the connector outside of chamber. It looks like a fuse
But the part I ordered, and AO Smith confirmed as being correct doesn't have it
oh, I see.... ok ... Can I ask what the part number they sent you is?
The bag says XXXXXXX, that doesn's seem like the right number, if I'm rembering my order correctly....
going to check my email records.
it is the right number, sort of. the bag is missing the last 3 numbers - 015
Yes
GVR 50 100
does it have the pezo lighter?
and the thermocouple wont screw into the gas valve, the one you got?
It will screw in just fine, I'm concerned I got the wrong part because the factory unit has this built in thermetic fuse, but the replacement part does not.
Oh... a fusible link
you're in CA.... that may explain it
Yet another ridiculous CA Law messing me up here?
Likely....
I cant find anything on an AO smith that requires it. Here's what it is. If the burner were to roll flames out, that link would melt and cut the pilot milivolt signal and ultimately drop the gas out.
I dont see that anywhere, even as an accessory
Me neither
I would ignore it
so I can remove the old one, and proceed with the install as if it didn't exist?
yes. I am looking in their complete parts book.
for all models too
If I were servicing it, I would install a standard thermocouple. I just dont see that in any parts or service breakdown
Is this the original thermocouple?
Yes, the heater is less than 4 years old. 3 years if you minus the house was empty due to foreclosure by previous owner.
it just doesnt seem like an AO Smith part.... wait... let me call a buddy
I can take a picture and send it to you if necessary.
By the looks of the backet that hold the fuse to rest of the burner assembly, I'd say it factory. Too clean and professional to be a replacement part.
bracket
Yeah, ok, I just called my buddy who works in the supply house. He says just use the thermocouple... he said they dont even stock it because none of the techs or customers want it
he said he had one guy adiment about it and they couldnt find it in their parts list either
and he's the AO smith distributor
but it is a thermal link
sometimes referred to as a fusible link
Wow, sounds like another dumb CA law strikes again. I'll use the replacement. Thanks for your help
no problem. go get your water hot
