Hello,

I am sorry for the delay. On the front wall of the furnace behind the gas valve is a flat plate the size of a credit card. Do you see this flat plate? It has 2 wires attached to it

you are great but i'll be monitoring the furnace should i get a back up limit or should the furnace be well for awhile
Customer reply replied 4 months ago
are you still there

The limit under normal conditions opens when too hot..like a dirty filter. Once cooled it closes. BUT, like with yours they can stick open. By tapping we just coaxed it to close and return to normal.

The unit will operate just fine but if it gets too hot and opens again it could possibly do the same thing.

You can replace it to have a new switch that will not stick open
