My stove is 12 years old, should I bother having the timer repaired?

If there are no physical problems with the range and you are happy with it, it is worthwhile having it repaired. It is not uncommon for ovens to last 20 or 30 years. Besides the timer, the elements and the temperature sensor fail occasionally, but these are not very expensive to repair.

When thinking about replacing an appliance, be sure to consider all of the hidden costs such as taxes, delivery fees, the cost to dispose of your current appliance, etc.
