I reached out to my tech contact at MaxxFan about your MaxxFan Deluxe Roof Vent # MA00-07500K and he said the flashing and beeping shows a voltage issue. It is either too high or too low to function correctly so the unit is trying to alert you to the issue.

If you don't have a voltage meter, you can use the Powerbuilt Digital Multimeter # BTMT15 and select the 20 V on the reader in the 10 o'clock position. This will give you the voltage reading going to your fan so you can see if you have a wiring issue or a battery issue.
