Sounds like a switch is bad on the Husky jack. This would have to be sourced at an electronics store. Also, the power supply feeding the jack may not be sufficient for the load to raise and lower the jack; the 12v feed on a vehicle 7-way may not be delivering amount of current the jack needs. A power jack often needs a dedicated trailer-mounted battery to get the required lifting power.

If you do have a dedicated battery, check and make sure you have a good ground at the jack mount with no rust or paint then ensure all the other connections are solid. Otherwise you may have a bad motor, or lifting screws broken and an entire replacement will be required.

I think the best value for an A-frame tongue jack is the Stromberg Carlson # SC63VR which is rated for 4500 pounds of tongue weight. This is 1000 pounds more than other models, and even though you may not need this much capacity, you will find that the jack motor runs quick and effortlessly. This will add years to its life. This jack also has a unique clutch that prevents damage from overextending or retracting the jack foot - the most common reason for jack failure. I also like that is has a generous 23" lift, including a time-saving drop-foot. It includes LED lights for operating the hitch in the dark, and a built-in bullseye leveling bubble.
