I can repair these Hytec 3360 Dimmer Controls for £12 + return postage if you want to send it to me. Or if you feel confident with doing the electronic repair yourself, I can supply a kit of parts for £6.50 + carriage of £1, with instructions, but you will need a soldering iron, a drill to remove the Triac existing pop rivet to get the heat sink off and a pop rivet gun to rivet the heat sink back on after replacing the Triac.
