where is the thermocouple??

I'm trying to figure out the part number for the thermocouple for my old Repco LA 100C gas fired boiler. Here is an exploded diagram and the part list:



looking at the image, i see the gas valve (1) and pilot (5) and there should be a thermocouple wire going from the gas valve assembly along the side of the pilot tube ending with a thermocouple near the pilot light. the thing is, i don't see it on the picture or on the list.

i took a picture of the boiler:



and i believe the copper looking wire going under the hood next to the pilot is the thrermocouple wire.

so why would it be missing on the part list and image? the boiler is 30 years old so i can't find the parts for it just by googling and i think i might be able to find it part number. except i don't have.

help?

No clue about the parts list Diver, sorry.
The copper line looks like it might be the thermocouple to me.
The aluminum line should be the the gas line to the pilot.
Look underneath to be sure.
Get a picture if you can.

Wouldn't a universal thermocouple work for this?

Peter,

I'm pretty sure it is thermocouple, i just don't get why it's not on the part list!

drooplug,

is there a part number for a universal one? i cold figure out the voltage from the electrical diagram, unless they all are the same ...

I don't know if they are all the same, but I would assume the universal work in a lot of appliances.

This is a 24" model, but they also offer 36": 24 in. Universal Gas Thermocouple-CQ100A1013 at The Home Depot

Go to any good hardware store, and ask for a thermocouple. 95+% of them are all the same, except for the length. Good luck.
