Routine Generator Maintenance Uncovered a Hidden Over-Crank Problem

This one started as a standard annual maintenance call. Nothing out of the ordinary on the surface - just a routine checkup on a Generac standby generator. But once we got the panels off and started digging in, it became clear this unit had a real problem hiding underneath.

The culprit was sprinkler spray. Over time, water had been getting into the unit and causing corrosion and wear on internal components. You can see the rust staining and damage to the housing and wiring areas - the kind of thing that builds up slowly and doesn't throw any obvious warning signs until something fails at the worst possible moment. The customer had no idea any of this was going on. That's exactly why annual maintenance matters.

We diagnosed an over-crank fault, which means the generator was struggling to start properly - a direct result of the water damage and component wear that had been accumulating. Left alone, this eventually leads to a no-start situation when you actually need the unit to kick on. We replaced the damaged parts with Generac OEM components, which is important. Generic parts might fit, but OEM components are engineered specifically for that unit and are the right call for a reliable repair.

What we ended up with was a generator running the way it should again - clean, tested, and ready to do its job. This is what a thorough maintenance visit looks like versus a quick once-over. We're not just checking fluid levels and calling it done. We're getting into the unit, looking at what's actually happening inside, and catching problems before they turn into emergency calls during a storm or outage.

If your generator hasn't had a proper inspection lately, it's worth getting one scheduled. You might be surprised what's been quietly developing inside the enclosure - especially if sprinklers or standing water are anywhere near the unit.
