True confession time: I am the laziest tech you’ll ever meet. That’s why I LOVE computer-controlled appliances- I can troubleshoot almost any problem from the main computer board with minimal disassembly, using the skills that we teach in our appliance repair training classes.
Using this Samsung electric dryer as an example, I show how use the schematic to troubleshoot and precisely identify the problem in this no-heat dryer all from the control board.
By doing all my troubleshooting from the main computer board and identifying the bad part, I can then check my inventory to see if I have the part on hand at the service call.
If I do, great- I go ahead and disassemble to complete the repair.
If not, then I avoid an unnecessary disassembly on that first call, go order the needed part, then come back and complete the repair with just one disassembly.
Avoiding unnecessary disassembly saves time, money, and liability.
Lazy techs work smarter, not harder, and earn more money!
