Texas Instrument 7" Limit Switch ??
This is for my Trane Gas Pack
Can't for the life of me find the following 7" limit switch online ? That tells me I may not be able to find it at the local supply house ? Any help on finding it or what to ask for at the supply house ?

If you can't find one, couldn't you just change out the snap disc?
might as well jumper the limit if one did that. The reason for the 7 " limit switch is to a more accurate temp reading between the h.e. cells.
Thanks Flash and all...
The contacts / terminals were corroded. I couldn't get a good volt or ohm reading yesterday when I looked into it. I sand- papered the lugs and put new FM connectors on the wires. It may have been the cause of the fault. The disc may have been stuck - it ohm'd when I tapped it...worked fine when I restarted.
Its a THT 1221 / new THT2436 - I got the part # from the manual. I'm on the the way to Trane to pick one up.
The HX looked good. But I have to get an inspection mirror to get a look at more of it.
