Some food for thought
Assume one hour per use, one use per day, 365 days per year, 8 years
of service to date.
365(8) = 2920 hours of service to date.
My guess is that the design B-10 life (point at which 90% of units
have not failed) is somewhere around 5,000 hours.
(It may be a lot less)
B-10 is a statistics term often used as a design life point, IOW,
the unit has consumed approximately 60% of it trouble free
As a recent homeowner, you have yet to learn about the slippery slope
of increasing repairs you face with household appliances as they age.
Clothes washers, clothes driers, and dish washers are the worst
followed by microwaves.
Stoves and refrigerators (Ice maker excluded) tend to have a much
longer service life.
Having to pull the appliance out of a cubby hole to gain access to the
innards, all the time making sure you don't plow a groove in the floor
covering gets your juices flowing, especially at 10:00PM on a work
Then realizing that you don't have the special tool the repairman has
to get at a special screw in order to make the repair, frustrated you
ask yourself, "How the F**K do I get out of this mess?"
You have two choices, go down the road above or wisely avoid the trap.
There was a time in my life when the only things I would not try were
brain surgery and laying concrete, but I'm learning, the list is
longer these days.
