The multimeter will now show a low resistance reading (indicating the switch ON).If the above tests are positive then we can assume that the triac is healthy. Anyway this test is not applicable triacs that require high gate voltage and current for triggering. Circuit for testing a triac. This is another approach for testing a triac. Use a multi-meter to test the fuses and thermostats for continuity after removing the wires, or you can bring them into U-FIX-IT and we will test them for you, free. Order a new: Heating Element, Dryer Fuse, Dryer Thermostat. See related videos here. Whirlpool makes dryers for Kenmore, Sears, Estate, Roper, and KitchenAid.
Some familiarity with multimeters and computer components is required to properly test a motherboard. The motherboard of a computer provides the platform for the majority of the machine's components, allowing the use of complex circuitry without needing confusing wiring schematics.
