After two days of no heat, I fixed it myself! (my first HVAC repair...ever)

I was Unsuccessful finding 350 degree relay, so I opted for one that's 310 degree. My question is - How long shall this one last?

A little more info please. Most relays have electric ratings for how many amps
they can run through them, and they make with 24 volt coils and 120 volt coils.
So what is a 350 degree relay? Paul

I think he means limit switch not relay.
How long this switch will last depends on how often it opens & closes.

I wonder what he is working on, 350 degree limit is a hi setting limit. Never seen one that hi on a furnace, unless it is a fire damper above the furnace. Paul
