Repairing an automatic gate is not among the easiest jobs to do. Very often, in fact, it may be necessary to contact qualified people who know the layout of the system better. However, if DIY is your passion, you can optimize the result by following the advice listed in the following steps of this electric gate troubleshooting guide where you will find all the information on how to repair an automatic gate.
Electric gate troubleshooting
You will need:
- Tester
- Welder
- Electrical repair tools
- Switch from scratch
- Silicone grease
- Spray lubricant
Carry out a preliminary check
First, try to locate the problem. Only when you have an idea, can you find an appropriate solution? For example, try to understand if the fault is visible and therefore without taking anything apart. The mechanical transmission device similar to that of a bicycle must be fairly clean and aligned. The various motion and safety sensors should also look good too. Otherwise, try cleaning or replacing them. If you deem it necessary, you could also disassemble the mask that protects them from the weather to check their condition. As for the remote control, replace the batteries and make sure that the LED lights up.

Connect the motor to the network
Check the above points, uncover the control unit and check the fuses and the voltages applied to them, perhaps trying to measure them at no load at the output on the control board. In addition, also check for the presence of any warning lights and then identify the relays, so as to ensure that they emit the classic closing click. However, do not disassemble the electronic board or unsolder its components before having made any other tests. If, on the other hand, you decide to test the correct operation of the motor and the mechanical transmission of the gate, disconnect the power from the switch that powers the entire circuit. At this point, connect the motor to the network with another cable. If the fault occurs in the circuit breaker, then you should use another load.
Use silicone grease
Once you have solved the problem, before assembling the gate lock it is advisable to lubricate it properly. In this case, you can opt for a spray or silicone grease. Maybe you use the first in some inaccessible holes, while the second you apply it with the tip of a screwdriver on the parts that are easier to reach. After this intermediate phase of the intervention, proceed with the assembly of the control unit, after which you just have to ascertain if your repair was successful. In that case, you have been good and you have also saved a lot of money.
The most difficult part to test is the control unit, especially if it is an integrated circuit and the diagram is not known. Then look for that integrated circuit on the internet and take note of the input and output signals.
