2022-2025 Ford Maverick 400W Power Inverter: Why The Outlets Stop Working
Your complete guide to diagnosing and replacing the 400-watt power inverter module in your Maverick Hybrid, and what to check before buying a used one.
- This power inverter is for the 120V accessory outlets ONLY and is exclusive to Maverick Hybrid models; its failure does not affect the truck's ability to drive.
- Before replacing the inverter, check for common, simpler issues like a blown 60A fuse (#84 under the hood) or a loose factory wiring connector behind the rear wheel well.
- A common fault code associated with a failed inverter is B1330. Scanning for codes can help confirm the diagnosis.
- When buying a used inverter, verify the part number and carefully inspect the electrical connectors for any signs of corrosion or damage.
Common Symptoms of a Failing 2022-2025 Maverick Power Inverter
When the 400-watt power inverter fails, the main sign is that the 120-volt outlets will stop working. However, the specific symptoms can help you narrow down the cause.
- No Power to Outlets: The most obvious symptom is that any device you plug into the cab or bed outlets simply won't turn on.
- No Indicator Light: The small amber/orange LED indicator on the outlet itself will not be lit when the truck is on and in the "Ready to Drive" mode. Some owners report the light may flash briefly on startup and then go out, indicating a fault.
- Flashing Indicator Light: A flashing light on the outlet typically indicates a system fault, such as drawing too much power or overheating.
- "Power Inverter Fault" Message: A message may appear on the driver information screen indicating a problem with the system.
- Diagnostic Trouble Code (DTC): If you scan the vehicle with a tool like FORScan, you may find specific codes related to the inverter. A common code reported by owners is B1330 - DC/AC Inverter Module, which points directly to a fault with the inverter itself or its wiring.
Pro Tip: Before assuming the inverter is bad, always check the simple things first. Make sure the truck is fully on and in "Ready to Drive" mode, as the outlets are not powered otherwise. Also, ensure the device you're plugging in does not exceed the 400-watt limit. High-draw items like coffee makers or large power tools will trip the system.
Diagnosing a Faulty Power Inverter
If your outlets aren't working, follow these steps before buying a new part:
- Check the Fuse: Owners have identified fuse #84 in the under-hood fuse box as the 60-amp fuse 🎬 Watch this quick guide on checking for simple inverter power fixes. for the power inverter. Check to see if this fuse is blown.
- Check for Loose Connections: A surprisingly common issue is a loose electrical connector from the factory. Some owners have found a disconnected plug under the bed or behind the rear wheel well that, once connected, restored power to both outlets.
- Try a System Reset: Unplug all devices from the outlets. Turn the truck off and then back on again to see if the system resets. If you've overloaded the inverter, this may be all that's needed.
- Scan for Codes: Use an OBD-II scanner or a more advanced tool like FORScan to check for trouble codes like B1330. This can confirm if the vehicle's computer has detected a fault in the inverter circuit.
Known Issues, TSBs, and Recalls
As of early 2026, there are no specific recalls for the 400-watt power inverter module itself. However, owners on forums frequently report issues with the outlets not working from the factory due to loose connections or early module failure. Some owners have had the inverter module replaced under warranty by the dealer. Always check for any applicable Technical Service Bulletins (TSBs) with your dealer, as software updates can sometimes resolve electrical issues before resorting to hardware replacement.
Buying a Used 2022-2025 Maverick Power Inverter
Warning: This inverter is only compatible with 2022-2025 Ford Maverick models equipped with the 2.5L Hybrid engine. It will not work with the 2.0L EcoBoost models.
A used OEM inverter can be a cost-effective solution. Since this is a relatively new vehicle, aftermarket options are scarce and may not integrate properly with the vehicle's systems. Here’s what to check when buying a used unit:
- Verify the Part Number: Match the part number exactly. Known part numbers include N1PT-19J254-DB, N1PT-19J254-DC, and NL3T-19G317-AC. Superseded or newer part numbers may also exist.
- Inspect the Connectors: The electrical connectors are the most critical part. Look for any signs of corrosion, bent pins, or damage to the plastic housing. A bad connection is a common point of failure.
- Check for Physical Damage: The inverter is an electronic module housed in a metal case, often with cooling fins. Avoid any units with cracked cases, heavy dents, or broken mounting tabs.
- Ask About the Donor Vehicle: If possible, get information about the vehicle the part came from. Avoid parts from flood-damaged or heavy-collision vehicles, as water and impact can cause hidden electronic damage.

Frequently Asked Questions (FAQ)
Why did my Maverick's 120V outlets suddenly stop working?
The most common reasons are overloading the system by plugging in a device that draws more than 400 watts, a blown fuse (#84 in the under-hood panel), or a loose connection. In some cases, the inverter module itself has failed.
Is the 400W power inverter the same as the DC-DC converter?
No. The 400W power inverter is an optional accessory that converts high-voltage DC to 120V AC for the outlets. The main DC-DC converter is a critical component on all hybrid models that steps down high-voltage DC power to 12V DC to charge the 12-volt battery and run the truck's standard electronics. A failure of the main DC-DC converter would likely prevent the truck from starting or cause many system-wide electrical failures.
Where is the power inverter located on the Ford Maverick?
The power inverter module is located under the center console, between the driver and passenger seats. 🎬 See how to remove the center console to access the module. Accessing it requires removing several trim pieces and the console itself.
Can I install the 400W inverter system on a Maverick that didn't have it from the factory?
While technically possible, it is a very involved process. It requires not only the inverter module but also the specific wiring harnesses that run to the outlets and the fuse box, as well as the outlets themselves. For most owners, using a high-quality portable power station or a smaller aftermarket inverter plugged into the 12V socket is a more practical solution.
