We troubleshot a GE Advantium Speedcooker for a no convection bake problem. Turned out to be a non-resettable TCO that had failed open. The customer agreed to replace both parts on our second visit.
Watch how I used the schematic to select strategic voltage and current measurements needed to identify the problem.
We did all our troubleshooting from the control board without uninstalling the oven. Doing it this way allowed us to diagnose the problem with minimal disassembly. We half-split the problem between the control board and the heating circuit and fixed the problem on the second trip.
By the way, these same troubleshooting techniques work on any appliance, regardless of brand or type, including SAMSUNG!
Troubleshooting electric circuits is easy and fun if you know how to read schematics and understand basic electricity!
