Bottom line---as a warranty servicer---it usually pays to keep digging (sometimes for several months,unfortunately) until you get an answer that solves your customer's
I don't know about your customers, but mine don't like to wait several months.
Allow me to better articulate what I mean...
Back in 2000 or '01 I had a Frigidaire warranty customer with a front load washer--about (3) months into the warranty. The complaint was NO high-speed spin.
Replaced the Motor Controller and all was well.
Two weeks later--same symptom.
Another Motor Controller was installed and the washer performed as it should.
The Motor Controller failed yet again after a week or so.
At this point I contacted Frigidaire Tech Assistance and explained that the customer had asked what--if anything--they could do to prevent this failure. Why was it occurring? The warranty is for ONE year not ten years.
The answer I was given wasn't exactly helpful:
"The Motor Controller has failed due to a TRANSIENT EVENT."
My reaction was: "What??? What hell's that & what caused it"?
Reply: "We don't know." "Replace the Motor Controller."
After installing the new Motor Controller--I informed the customer that I did NOT know why their part kept failing--but that I'd notify them as soon as I got a definitive answer.
Sure enough--a few months passed and Frigidaire published a bulletin indicating that *electrical noise* from the contacts in the mechanical timer was "corrupting" Motor Controller programming.
I contacted the customer and replaced the motor controller with the updated version--which had the addition of several black jumper wires on it. These were *Noise Filters*.
Since that episode--I've taken a more active approach to finding answers rather waiting for it to reach me. Cuts a LOT of time.
Many bulletins that publish problems are released monthly--having the right connections (quality people) gets you this information *before* the release date.
Today--most types of computer glitches are reported early and often. A mere ten years ago--EVERYONE--was still on a "learning curve" with digital/electronic componentry.
and certainly the servicers.
Took a long time--but it's coming together.
