Well first you ought to cross check the other functions first and make sure you are in 2T and all your other knobs except amps are turned down. Check and make sure the wires on the plug have not come loose. Then check the wires on the torch switch itself. Likely one has slipped off.

Pins 1 and 2 are the ones on that one.
