When faced with error codes, it can be all too tempting to just read the error code description and swap out whatever part it says is at fault.
But beware, this is parts-changing monkey thinking.
Fault code descriptions rarely provide all the information you need to make the correct repair. What error codes do is direct you to the general area of the schematic you need to look at to find the problem.
To see this in action, check out this video where the Samurai diagnoses an F30 error code on an Electrolux dual fuel range:
As you saw, the F30 error code said only the RTD was open, but said nothing about the hi-limit. Only by looking at the schematic and seeing that they were in series did the Samurai find the real cause of the fault code.
Fault codes tell you where to look. You still have to use the schematic and then manually verify on the machine the root cause of the error code. It’s often not what the tech docs say it is. This is a how a master tech uses fault codes to troubleshoot an appliance.
