Diagnosing the problem is usually the hard part. It can get real expensive to just start throwing new parts at the problem. It’s worth $100 to get the right diagnosis sometimes. When our chest freezer quit working I paid to have it diagnosed, then bought and replaced the correct circuit board myself.
“Diagnosing the problem is usually the hard part.”
Yep. Had the freezer portion of a side by side quit functioning about two years in. Started digging around online for some clues and determined the defrost element was toast. Replaced both of them in about two hours (a royal PITA) and it’s been going strong since(knocking on wood).
I was driving home one day and noticed someone had thrown a Stihl grass trimmer to the curb. I decided to pick it up and take on the project to diagnose and repair. I went online to diagnose after having no spark to find it was a coil pac. 30 dollars later and now runs great.
