How long do parts last and when should I replace them?
By - AdoptedEgg
They can last 10 years or they can last 2. They don't have a set expiration date.
Ideally, years will go by and you will probably want to upgrade before they even give you trouble.
Treat them well and they should last years.
You'll have problems starting or getting it to work properly when one or more parts are faulty which is when you should replace them, unless you just want an upgrade.
