total noob Posted August 26, 2012 Share Posted August 26, 2012 Hi friends, My Ct-48 is acting weird, It used to be that once the change was inserted you heard a buzz and then had time to open which door you wanted, Now, recently you have to pull on the door while putting the last quarter in or else you lose the window of opportunity. It seems that now that switch only engages for the same duration as the buzz. Is this a relay? I am a total noob as you can tell by my name and im just learning. any help would be much appreciated. Thanks a lot! Link to comment Share on other sites More sharing options...
jasonkw Posted August 26, 2012 Share Posted August 26, 2012 The CT-48 is a machine that's been out of production for 20+ years (I think closer to 25 years!). I've taken this machine out and apart numerous times and am quite familiar with it. When the last coin is inserted, there's an electrical current that flows to the solenoid mounted on the right side of the rack. This causes the switch to pull back, unlocking the doors, until one of the doors are opened. Seems like in your situation, the switch didn't stay in the pulled back position - rather, it's pulling back and jumping back to the original locked position. The only thing, if I recall correctly, that holds the switch back is a white plastic pin. If that thing is dislodged, damaged, or not oriented correctly, it will not hold the switch back causing your issue. That would be the first thing I would check. - Jason Link to comment Share on other sites More sharing options...
Walta Posted August 26, 2012 Share Posted August 26, 2012 Almost all the problem with that machine are caused by spilled soda gumming up the levers I would start by removing the vend rack keep the electric parts dry and clean it with a hose warm water is best.

Vendergy Posted May 6, 2013 Share Posted May 6, 2013 Jason kw, I have the exact same problem with total noob, but my machine is brand new sealed box. No gum or soot to worry about! Could it be a ground or voltage problem? It's not plugged into a wall, but a circuit breaker strip that may only have two prong. the switch didn't stay in the pulled back position - rather, it's pulling back and jumping back to the original locked position. any help would be great!

Henry.lin@aol.com You'd be better off plugging the machine directly in to the wall plug. It's a bad policy to plug any compressor into a power strip - even a small one like we're talking about here, If you must use an extension, keep it as short as possible and rated at 20 amps (12/3 cord or bigger) Link to comment Share on other sites More sharing options...
Walta Posted May 6, 2013 Share Posted May 6, 2013 Most likely is the 20 year old factory applied grease and oil have dried out and turned gummy and sticky. I think you will need to disassemble it clean and reassemble. Walta Link to comment Share on other sites More sharing options...
Vendergy Posted May 7, 2013 Share Posted May 7, 2013 Thanks walta and moondog for the reply...I'll try it! Link to comment Share on other sites More sharing options...
Vendergy Posted May 10, 2013 Share Posted May 10, 2013 No gum or sticky soot, seems like the solenoid doesn't pull the lever back far enough to allow the white plastic thing to catch...it worked two times out of 10 tries..that's the average! Voltage? Spring too tight? Link to comment Share on other sites More sharing options...
Vendergy Posted May 12, 2013 Share Posted May 12, 2013 I can't get the price setting right...it vends at all kinds of prices! Rocker switches seems like they don't work! Link to comment Share on other sites More sharing options...
