Request service if your generator won’t start, shows a fault code, or didn’t power your home during an outage. We’ll diagnose the issue and restore reliable backup power.
These quick checks take 1 to 3 minutes and often explain why a generator won’t start, won’t switch power to your home, or isn’t powering the way it should. If you smell gas, hear hissing, see visible damage, or the area is flooded, stop and request service.
If you use natural gas, confirm the gas valve is fully open. If you use propane, confirm your tank is not low. Fuel issues are a common reason a generator will crank but not start.
Most standby generators have a breaker on the unit itself. If it is OFF or tripped, the generator may run but not send power to your home. If it’s tripped, reset it once.
Look at the control panel and note any message, warning light, or fault code. This helps us diagnose faster and arrive prepared with the right parts and tools.
A weak battery can prevent starting. Look for battery-related alerts, and check for loose or corroded battery connections. If you see heavy corrosion, request service.
If the generator started but your home stayed dark, the system may not have switched power over. If utility power has returned, confirm your home’s main power is back on. If the generator ran but never powered the home during the outage, request service so we can test the transfer safely.
Remove leaves, palm fronds, and debris around the generator. Keep the sides and vents clear so it can cool properly and run safely.
Find the code on your control panel (or in the Mobile Link app), then use this section to choose the right next step. If a code returns after you clear it, request service so we can diagnose it safely.

Best time to schedule: For most homeowners in our service area, the ideal window is late summer through fall (August–November). You'll be prepared before winter ice storms and spring severe weather with a generator that's been serviced, tested, and documented.
When severe weather approaches: As weather warnings are issued, we prioritize urgent needs first—generators that won't start, active fault codes, and homes without backup power. Maintenance plan members receive priority scheduling during peak demand periods. Routine maintenance may pause so we can focus on critical system failures.
After severe weather events: Response times depend on road conditions, damage assessments, and call volume. We'll keep you informed and work through service requests as quickly and safely as conditions allow. Members are scheduled ahead of non-members during peak demand.
