If it's a Maytag, Whirlpool or another older super-reliable machine then you might consider fixing it yourself (if you're handy with tools) or finding someone to fix it. If you want to replace it with a good washer, then know that there are shops who sell rebuilt/refurbished models of the most trustworthy appliances.
Meanwhile for DIY-ers, parts are usually available and there are YouTube videos on most major models (telling you which models are best, how to fix/maintain them, how to run them, etc.).
We have a Whirlpool Ultimate Care II that is about 50 years old and has been thru 4 generations of people. I've worked on it twice: once to replace a switch and the second time to replace some ratchet gears. Repairmen have also worked on it in my absence. Like most of the older washers, it's designed to be easy to dismantle and repair. It washes more gently than any other washer I've seen: consequently our clothes last longer. Wish the software I use was as easy to fix.
I replaced the pulley drum belt with a kit and the squeaky roller wheels for my whirlpool dryer.
That thing is a tank and so easy to service!
I’m just scared it will fail catastrophically some day and the gas burner will ignite the garage. Do you know how safe an old gas burning whirlpool dryer is compared to modern gas dryers? The whirlpool can get super hot and basically bake my clothes if I want.
I don't see how you can do more than
- have a professional check out your dryer periodically,
- clean the lint trap every cycle and
- periodically clear lint out of the exhaust duct (all the way to the duct's exit).
OTOH I personally would not use a gas dryer in a home. While gas is faster drying and lower cost, an electric dryer is simpler and less worrisome. Sometimes "Less is more." And if you prefer an older electrical model, they are available! Perhaps a re-furbisher would take your gas dryer in trade?
The last two maintenance items above should be done for electric dryers too, since electric dryers can ignite trapped lint as well as can gas.

I particularly like their suggestion to put a smoke alarm above the dryer, which I will do today!
