I had a very troublesome clothes dryer that I purchased new in 1964. It immediately developed an extremely annoying "whine" that emanated directly from my ex-wife. She was convinced that there was something terribly wrong with the dryer, so we called in a service person - who made the roughly 200 mile round trip "service call" and was unable to find anything wrong with the dryer.
The annoying whine persisted until I made the same 200 mile trip to the nearest city large enough to find a new drive belt for the dryer. (about $7.00 US)
The annoying whine immediately ceased and all was peace and goodness. Money had been spent, so the problem was gone.
(Similar noises persisted related to other "problems" so I eventually replaced the ex-wife.)
In 1991, the original drive belt finally broke, so I installed the "new" belt, which had been safely stored, unopened, for 27 years.
My new trophy bride was not impressed at all that I already had the belt. She was immensely impressed that I knew exactly where it was - and that the original receipt was still attached.
The dryer worked fine with the new belt, and was sold almost immediately so that new bride could have a new matched set - washer and dryer.
