Maintaining Your Automatic Transfer Switch
Last verified: September 2026
An automatic system asks little of you — but not nothing. Here's the light care that's yours, the service that's the pro's, and why the battery matters most. Questions? My number is (330) 200-8042.
Maintenance, at a Glance
An automatic backup system asks little of you — but 'little' isn't 'nothing.' The transfer switch itself needs very little; the generator, being an engine, needs real care — oil, filters, a spark plug, and especially the battery, the top cause of a no-start — done by a professional on schedule. Your part is light: keep the area clear, watch and listen, and call a pro on time. There's a printable 29-page version up top.
Common Questions
1 Does an automatic system really need maintenance?
Yes — 'automatic' means no effort during an outage, not 'never needs anything.' The generator is an engine that needs oil, filters, and battery care on schedule, done by a pro.
2 What's the most important part to maintain?
The battery — a weak or dead one is the top reason a standby generator fails to start. Have it checked regularly and replaced before it wears out.
3 What can I safely do myself?
Keep the area clear of snow, leaves, and clutter; listen for the self-test; glance at the status lights; and, on propane, watch the tank level. Look and listen — never open or adjust.
4 How often does it need professional service?
Commonly about once a year, plus attention after a number of running hours — follow your manual. Many owners set up a service plan so it happens automatically.
5 Can I change the oil myself to save money?
Best not to — it's part of a fueled, wired system, and DIY work can be unsafe and can void the warranty. Leave the engine and wiring to a qualified pro.
6 How do I know when service is due?
By the calendar, the running hours on the hour meter, or the system's own warning lights and a rough self-test. Keeping records makes it easy to stay on schedule.
Would You Rather I Just Help?
Keeping your system ready year after year is exactly the kind of ongoing help I love to provide — a simple care routine, friendly reminders, and lining up professional service. $99 flat for a visit, 30-day come-back-free.
Would you rather I just do this for you?
No shame in it — plenty of folks would rather hand it off, and that's what I'm here for. I'll come to your home, set it up right, and make sure it's working before I leave. Flat $99 per visit — no jargon, no upsell, and every visit is 30-day come-back-free.
Not a hardware job? I can often fix it remotely for $49 — a secure screen-share, up to 2 hours, that you watch the whole time and can end whenever (included free for $39/mo Support Plan members, and it counts toward the $99 if it turns out I need to come out).
