If your toaster uses a TRIAC instead of a RELAY, then use the testing procedure outlined here:

• Remove triac from the circuit board(desolder).
• Identify the pins.(Usually MT1 / MT2 / Gate - Left to Right)
• You will need a desk lamp or drop light, short extension cord, jumper wires, 1" or 2" long nail, and a 330 to 470 ohm resistor
• Plug the small blade of the lamp or light into the small slot in the extension cord receptacle(WHICH IS NOT PLUGGED INTO AC POWER!). Leave the wider blade OUTSIDE of the receptacle along the side of the receptacle(DO NOT insert the wide blade into the wide slot!).
• Insert the nail into the wider slot not being occupied by the lamp cord which is plugged into the extension cord receptacle.
• Using a jumper wire connect the nail in the wider slot of the extension cord receptacle to the MT1 terminal of the triac under test.
• The wider blade of the lamp which is not plugged into anything, which is along side of the extension cord receptacle, will be connected to the MT2 terminal using a jumper wire. -DO NOT touch anything. Now plug in the extension cord into the wall receptacle. The light should be OFF. -Next unplug the extension cord from the wall receptacle, and connect another jumper wire from MT2 to the 330 - 470 ohm resistor. The other side of the resistor will be connected to the GATE of the triac using another jumper.
• DO NOT touch anything. Plug the extension cord into the wall receptacle and this time the light should be on if the triac is not faulty.
• TESTING COMPLETE-
