Check for obvious bad contacts. The next thing to check is the loop detector itself. Since you are checking inductance measured in Henry's it would be good to get the specs from manufacturer Try calling customer service.

ok, try purchasing a Chilton Manual (NOT a Haynes- it's junk). In it you'll find the complete wiring diagram.

Thanks for choosing FixYa and welcome to the site. You need to make sure that your fuse is not blown. Check your fuse box diagram for the location. If the fuse is fine, you may have a bad switch. There could be a loose wire or a bad connection to the switch.

Why does the gate open on its own during the day with nobody home?


There are several ways a gate will open. You need to check each of them but the most common issue we find when repairing gates is the exiting vehicle detection device is opening the gate.

There are two main types. The best type will be a loop embedded in the driveway. These normally open the gate by driving over them. A sensor in the operator sends an electrical wave through the loop. A vehicle affects this wave and the sensor detects it, flips a switch and opens the gate.

If the installer used standard PVC wire, and the driveway cracks to let water sit on the wires, they could change the wave occasionally and open the gate. Water can take days to soak through and remain around for days. So while you do not have rain or sprinklers going the day the gate opens, it could still be the cause.

The sensor inside the operator could also be going out. Usually, they have lights showing when they are active. If you have one, and the detection light is on, turn off the machine, disconnect and reconnect the sensor and see if the detection light comes back on.

Next check the loop wires. Physically, look at the wires wherever you can. Check the driveway for exposed wires. If you find them, call a pro to replace them. Once this is done, you need an ohmmeter. Plunge a screwdriver deep in the ground. Set the dial on the ohmmeter to measure how much resistance there is between one wire in the loop and the screwdriver in the ground. Make sure you are not touching the leads or wires with both hands since you will be measuring your bodies resistance and not the short between the ground and the wires you are looking for.

If you find anything but an open circuit, there is a problem with the loop wires and you will need to replace them. If you have a completely open circuit, then change the detector. Ideally, you have another detector for the safety loops and can switch them to see if the problem moves to the safety loops. If it does, replace the detector.

The second type of exit device is called an exit wand or exit probe.

These are overly sensitive and don't last as long as the loop detector. Your dogs collar can set it off as can a bicycle or even a workers steel-toed boots. Add to this, the propensity to fail, and if you have one of these, you have likely found the problem.

The fix for these is to pull the probe up, look for nicks or cuts in the wire and fix them, dig a deeper trench, cover the wire with PVC pipe to prevent more cuts and finally bury the wand itself at least six inches deep. By the way, if the probe cable runs next to other electrical lines, they can make the probe react too. I have heard this can be prevented by using copper pipe instead of PVC pipe.

Other causes could be a remote in someones purse or pocket going off as it bumps around, a switch used to open the gate shorting out, a call box getting signals and in general anything used to open the gate breaking down or being set off inadvertently.

Rarely, and I mean very rarely, a control board, the big circuit board controlling the gate motor itself, will go out and cause this sort of problem. Out of everything, this is the least likely.

Good luck.

Try to reprogram your remotes.... or replace the batteries even if the l.e.d. still works (it only takes half a volt to make the l.e.d. work but almost the full charge of the batteries are needed to send a working signal.

The gear is getting stuck... i press on brakes and when car is in park it is hard to put on reverse.. the car runs great...


In all probability the brake sensor on the pedal is starting to work erratically. This sensor sends a signal to the shifter gate, and the gate will not open unless the brake pedal is depressed. I had it happen to me, and the only solution until i replaced the sensor was to hit the brake over and over until the stop light worked (You can check it while looking at the 3rd stop light in the rear view mirror). If the stop lights work, the shifter gate should allow the shifter to move out of park. This sensor/ switch is located about 3 inches above the brake pedal, and it is easily recognizable by the cable attached to it.

How to use 2 button remote for two mighty mule gate openers


I understanding that the chamberlin is a two button remote so as long as you have the same kind of recierver (a box hooked up in your operator that has dip switches,it recieves signals when the remote and it are set the same.) you should be able to use the two button remote on both machines. If not their is a reciever that is called multi-code and it is universal to work with all gate openers. the chamberlin remote you have will work with it.
