Question Trane XE60 Gas Furnace will not "fire"

My Trane XE 60 (American Standard TUP100B948A0) furnace is on the fritz. The blower will operate from the thermostat. Jumped R&W @ t-stat and got nothing Jumped @ furnace & got nothing. Fuse is brand new, gas valve is brand new (oof). Standing pilot is lit so thermocouple is good (yes?). I get nothing when t-stat should call for heat. No click and certainly no burner ignition. Could I have a bad (stuck) limit switch? HELP. Forecast is for 29 degrees tonight which is cold in Alabama and I know the tiny ceramic heaters are costing me a small fortune!

look for the small fusible link that is in series with the gas valve, likely it has also have a vent safety switch in series. should be one or the other.

IF it is a fusible link that is open then you need to call a repair person to look at your furnace. A fusible link is designed for 1 time use for a reason. IF the link is open then you have a serious problem with your furnace. A XE60 is a very old furnace also. It is roughly 60% efficient.
