Changing a PCB and measuring resistance of thermistor cirucuits does not constitute "Electronics" in my book, thats call part changing!!
However tracing wiring back to a Y plan JB and finding a broken connection stripping back and remaking a poor cable connection is Definately Electrical!! - and if a Service Engineer cannot do this then he/she is not really a Service Engineer at all!!
