To fix the AC outlet issue on your DieHard 28.71688 that switches to compressor, follow these steps:
1. Ensure the battery clips are securely stored in their holders. 2. Open the protective cover of the AC power outlet. 3. Make sure the 110V AC device is turned OFF before plugging it in. 4. Plug the device into the AC outlet. 5. Press the Select button to switch to AC power mode.
Note: This inverter uses a modified sine waveform. Check your device manual to confirm it is compatible. Also, use a 16 AWG or larger extension cord no longer than 50 feet for best results.

@Mr. Anderson
I have done all of these steps. As soon as the AC light comes on it blinks and switches to compressor mode. I'm not getting any power to my device. I've tried multiple devices and nothing is working with the AC and it still keeps instantly switching to compressor mode. I'm not sure what is wrong with it. Everything else seems to work fine.
