I order parts for our company and on several occasions (once on an oven, the other on a washer) when the tech has gone out to the call and its for a property management or the person who makes the decision to repair was not there, but he'll call and tell me the diagnosis and what part it needs. Then I look up the price of part & if it's available total up the cost to repair and call the customer to tell them whats wrong, how much to repair and collect a deposit. Here's my problem... On the occasions I've mentioned above, when the tech calls he tells me it could be a display board or a control board so price it out to the customer as if the c/b fixes it great & it's this much$ but if it doesn't itll need the display board so it will be this much $. Now, I have even sat here while he calls tech support and basically I think tech support just thinks everything is under warranty because their answer is always change them both out. That's great if it's under warranty. But, when it's not... Why can't they tell if it's the c/b or display for sure before they put them in? Isn't there a way to test them to be sure?
And I know my tech has explained this to me, but I still don't understand and when I'm calling the customer and they ask, I want to be able to explain it to them with no hesitation in my voice when I explain it to them. So can someone explain it to me AGAIN why this is? Thank you
