Question: What would cause our electric jack to quit working? We have it plugged in, but it will not go up or down – any ideas?
Answer: Many things can cause your electric jack to malfunction. There are electrical and mechanical failures. Not knowing how your jack is failing, we can suggest some things for you to check:
You will have to identify the wiring and power source for the jack. Once you have established that the power is available at the source you will have to trace the wiring all the way to the jack. Look for a blown fuse somewhere in the circuit or a faulty switch. Hopefully it is just a blown fuse.
If the fuse and wiring are good, check the switch that extends and retracts the jack. If the switch is good then it is time to move on to the motor. Is the motor working and can you hear it? After you have eliminated the power source, the wiring, the switch, the fuses, and the motor, you will have to start to look for a mechanical failure at the jack itself.
If there are safety pins, have they been removed prior to attempting to operate the jack?
Look for bends or obstructions in the jack that might cause it to bind
Inspect all the gears to make sure they are fully engaged
Hope this helps. Let us know the outcome.
