what causes sensor to malfunction?

I wasn't told why It malfunctioned. The replacement we received has been working ever since!

I have not seen the sensor malfunction per say. I have had issues with people not knowing exactly where the sensor is and being caught off guard when candy is dispensed. Also the serving amount of small candy such as skittles can be quite large in all three settings, also catching people off guard.

I have not done much with the sensors to date. Most of the sensors are simple digital/ analog I/O interfaces which would just require an appropriate I/O selection on the microcontroller. If you have questions about a specific module, I could take a quick look and let you know. I had the same reaction with the lack of documentation but I am an electrical engineer so I am not particularly worried about figuring out the details.

Make sure the sensor is not covered. I don't know what else would be an issue

Could be. Try pulling the power. Then, disconnect the sensor wires and the wired switch wires from the rear of the unit. Plug it back it. Does it do the same thing?

The sensor is battery operated, however the battery and all of the electronics are encapsulated and as such not serviceable nor replaceable. The battery does however last several years under normal conditions.

The two sensors that are on the far right of the unit might be crusted with deposits.I would fill the base full with 1/2 water and 1/2 vinegar (if it's real full it will cover thesensors) or you can chip it off but be careful about damaging the sensor).

I had and have the same problem with 2 of my sensors. One I was able to correct by changing the orientation of the bulb insertion. The other I have just accepted since reinserting the bulb did not work

You could try cycling the power or shine a flashlight on the sensor to reset it.I took mine out as they were unreliable.

I had to replace one a few years ago. I believe I reset it so many times that the reset failed to function properly. I read Hippie Bob's suggestion and wish I had tried that before I discarded the original sensor. Good luck .

Yes. When re-installing the sensor make sure it's just the clean un damaged metal filament. It breaks very easily and is damaged very easily and won't work correctly. Half turn counter clockwise til it locks into place when re-installing. I'll be happy to answer any other questions you have later, just ask away

The sensors might be dirty or perhaps the unit is too close to a vent or air source. I took the front panel off of mine and blew on the sensor then relocated it slightly. It hasn't happened since.

Have you tried washing the sensor? Just use water, nothing else. My sensor got dirty and I had this problem. Cleaning off the sensor did the trick. And don't forget these are warranted for five years. When my motor died, they sent me a new motor with instructions how to change it out. Piece of cake.

Bad or loose connection recheck all conection or it could be a defective remote sensor

I had no problem with mine. Simply connected to post and has worked great. Suspect sensor not working. Get a new one and do not worry. Good luck

There is no sensor, it is on until you turn it off. I usually let mine run al the time.

Just look at the plug connector on the sensor your replacing, there are two types. Get the one that has the same style that needs replacing. Easy peasy!
