ReplyMay well find that the switch is doing its job! Low air flow, undersized ducts, oversized furnace...
Don't recall having limit issues with any A-S/Trane 90 that was the furnace's fault.

Short time lurker , first time poster . I had a Trane XV 95 furnace , XR 14 a/c , Trane Clean Effect air cleaner installed today . The furnace didn't pass the "sea trials" , the diagnostic light tripped , blinking 4 times saying the upper limit switch was open . They opened the blower cover , it tripped again . They drilled holes in the vents and got temps of 135 F . I didn't get scared till they started adjusting the high and low screws on the valve , which didn't stop it from shooting codes . They are sending a service tech out tomorrow w/ a new upper limit switch . I'm hoping that solves the problem . What a disapointment for all of us , nothing worse than getting to the end and not having it work . Forgot to mention it takes about ten minutes till shut down . I hope it is as simple as the switch . I assume it isn't a common problem. Sorry if this was a long read.

It aint that hard to stop a Trane. The trick is to stop it without it being noticable.Originally Posted by I_bend_metal

If you don't know, then don't do. If you don't know and still do, then be prepared to pay someone else a lot to undo what you did and then do it right.
If you do know, then do. But do it right. Otherwise, you may not be doing it long.

Sounds a bit oversized.
Was the old Rheem a 90% furnace. Or an 80% thet vented out a regular chimney.

I would say they used the manual E load calc on that one. The limit is doing its job I am sure, I would guess the service tech will be muttering some choice words to himself about their salesman.

That's a lot of furnace. Sis has same size house and 75K 92% furnace! And we get below zero each winter.
They better check static pressure of the duct system. Still think an airflow issue.

whats the duct size??? How big is the cold air drop? The vent pipes should be 3" and they can run out 200 liner feet? How many 90° elbows are in the vent pipe?
Why am I the only naked person at this gender reveal party
