Electric Tongue Jack Stopped Working HELP!

ykcamom · 05-15-2014, 06:26 PM

Hubby was unhooking the trailer, hit the power jack -- up it went, then made a "pop" noise and stopped.

Now it won't move. Any suggestions as to what the problem might be?

OK, problem solved. It was a fuse. Guess this was a good reminder to be sure we have extra fuses in the trailer! JEESH

Mine has an autoset circuit breaker. It trips when it needs to for whatever reason and after a few seconds will reset it self.

You might want to get one of those then you won't have to dig around for fuse somewhere.

I had 2 issues when my jack stopped working.

1. I had an electric jack from Harbor Freight. The machined pin that attached the gear from the motor to the screw sheared twice. Motor worked, but no movement. Solution was to buy a new jack.

2. While hooking up the new jack later in the season, it stopped working as if the battery had no juice. It turned out the power converter blew. Apparently it is common. We had a power surge on our previous trip and it apparently fried the circuit board. The way we knew this is that when hooked up to shore power the outlets worked, but all of the 12 volt items and the battery went dead. Replacing the converter ($150) solved the problem and the jack worked fine.

where is the fuse? My jack just did the same thing.

It is usually on the TT battery+ connection with a 30 amp fuse or circuit breaker, some have a built in circuit breaker. (Special the ones with 7 pole plug connection)
Always cover your TongueJack, haven't found a waterproof one yet.

My power jack will stop working at random times without blowing the fuse. I pull the fuse and reinsert and it starts working again. I have no idea why.

Mine died onour recent trip and I was advised that the oem jack was junk and to replace it. My new Bulldog 4000 lb was waiting for me when I got home. Easy replacement takes maybe 30 minutes and there is only one wire to connect. My new jack has a circuit breaker built in.

The switches on the Power Jack can get corroded a bit because of environmental conditions a little bit contact spray in the switch will help the situation.

Murphy's Law states that if you're camping and blow the fuse and put your last spare in there, and then go to every little grungy dirty garage and gas station and hardware store in every little one-horse town around where you're camping to find a package of spares and pay inflated prices just so you have some spares, you will never need them!

Don't ask me how I know.

For some reason, either the jack has broken in or I'm a little quicker in shutting it off, I haven't blown the fuse since that time.

Better to have them and not need them, than to need them and .... etc.

The oem Power Jack is just as good as the new Power Jack you buy. Keep the Power Jack from weather conditions and maintain it. Even the new Power Jack you buy has hardly any grease on the spindle and motor. So why not grease it when you buy it and every other year; it will last a life time. Put a cover over it to keep it out the weather.
