      If Q1316 is shorted e~c that would explain why the motor is on. I would replace it, Q1314 is likely ok.
      The KA is larger, you need to measure the original to see which will fit the pads.

        DTA143XKA or DTA143XUA

        Not sure if some values can be changed
        Thanks so much

                Would this be ok to use as an alternative if needed for q1314

                    My thinking is that when q1316 shorted it would have taken out Q1314
                    Because the emitter and collector shorted on Q1316
                    If I replace Q1314 and doesn't work it would be handy to have on hand to replace it
                    Could you advise of some suitable compatinle replacements please that is available on ebay or aliexpress. Thanks
                    Thanks

                      Go to EBAY, then type DTA143X, There is a ad for 5pcs X DTA143X 340t-23 The picture shows DTA143XKA
                      All you need to do is measure the case on the original to know which part to order. They are electrically the same, just the foot print is slightly different.

                      Q1316 likely shorted do to high current in motor, maybe the mechanism jammed causing the motor to stall and draw excessive current
