Chard Posted November 20, 2015 Share Posted November 20, 2015 Occasionally (once every couple of months) I have a GFI trigger on a Vendo 721. What could cause this? Link to comment Share on other sites More sharing options...
CajunCandy Posted November 20, 2015 Share Posted November 20, 2015 Moisture. Machine is outside or inside. A little reading material. http://thecircuitdetective.com/gfis.htm cajun Link to comment Share on other sites More sharing options...
AZVendor Posted November 20, 2015 Share Posted November 20, 2015 It probably means that the GFCI is getting weak. There may have been an original cause of the tripping the first time or two due to a possible surge or low voltage that caused excess current draw but every time it trips, the GFCI gets weaker. I have had to remove them from several power cords to get the false triggers to stop. You can just cut it off and install a replacement plug on the cord, then use it as a normal corded machine.

rmorris1953 Posted November 20, 2015 Share Posted November 20, 2015 GFI's purpose is to prevent electrocution in case of a short within the vendor. Cutting it out can make you financially liable should someone get electrocuted or catch fire. Pepsi policy was never alter a machine. If it is a bottlers machine they may replace it for free.

Chard Posted January 19, 2016 Author Share Posted January 19, 2016 Update: The other day the GFI clicked off completely. Resetting it would only work for a few minutes then it would click off again. Seemed to be either a bad GFI or a faulty compressor shorting out. Long story short it ended up being the GFI was faulty. Link to comment Share on other sites More sharing options...
lacanteen Posted January 19, 2016 Share Posted January 19, 2016 Once a GFI trips it gets weaker each subsequent trip and eventually fails. Link to comment Share on other sites More sharing options...
CapitalCityVendingLLC Posted January 20, 2016 Share Posted January 20, 2016 I had this same exact problem about 2 weeks ago on a Vendo 621. My machine would only stay on for 2-3 seconds after tripping it. I ended up ordering a new cord for ~$40 bucks. Good as new now. Easy to install too Link to comment Share on other sites More sharing options...
lacanteen Posted January 20, 2016 Share Posted January 20, 2016 You can get GFI replacement plugs for under $20. http://www.hhdonline.com//pc_product_detail.asp?key=980350077B5C4D25A38C873C7DCEA3BF Link to comment Share on other sites More sharing options...
Chard Posted March 2, 2016 Author Share Posted March 2, 2016 I installed a new GFI plug and the other day I found had the circuit breaker had blown. The employees there reset the breaker numerous times through the day only to have it happen over and over again. I came to find out a lady was selling food to the employees and had been putting a crock pot on the circuit with the Vendo 721 that kept tripping the GFI earlier. Some background at this point. The wiring on this particular circuit seems overloaded to me. We have four machines there currently (2 Refrigerated AMS and 2 Vendos). One circuit is devoted to an AMS and soda machine. We never have problems with this pair of machines. The other circuit has the other AMS and Vendo 721, a television and several offices on the same circuit. It is this pair of machines that has had problems. I believe the crock pot would kick on occassionally and at that point heat the circuit and cause the breaker to trip. What concerns me is low voltage on that circuit. AZ, you had mentioned that low voltage can trip a GFI which still happens occasionally. My consideration is to remove the AMS from this pair and replace it with an ambient temperature snack machine. This pair would go on the circuit that appears to be overloaded. That would certainly reduce the current draw on this circuit and hopefully prevent the GFI and the circuit breaker from tripping. What are your thoughts? Does this sound like the correct course of action? Link to comment Share on other sites More sharing options...
AZVendor Posted March 2, 2016 Share Posted March 2, 2016 That should fix it for you. Removing one compressor from the circuit should solve any breaker problems. While some circuits can handle two compressors it really depends on several factors besides other devices being on the circuit. Electronic items won't cause current problems but anything with a heater in it or a compressor will. Coffee makers, toasters, water coolers, microwaves all draw significant current. The older the compressor, the dirtier the condensers and if any are against the wall will increase the likelihood of a tripped breaker. Link to comment Share on other sites More sharing options...
