Snack Man 2000 Posted June 29, 2018 Share Posted June 29, 2018 I need some advice from someone that has lots of experience diagnosing bad compressors. The machine would trip my generator that I use to test my machines out at my storage location. The generator is an inverter generator that is over 2500 watts and will run any drink machine easily. I have many of the cb300 machines and 3505 combos and haven't seen this issue. It would trip the overload on the generator, so it wouldn't start.. So I pulled the refrigeration deck and took it to my shop. It worked perfectly at the shop plugged into the wall. So I assumed the start capacitor was going. I opened the unit, and couldn't believe there was no capacitor. So I installed a 3 in one. Now it runs for 5 minutes then the thermal overload trips. So I ran tests on the compressor. Here's what I found: Start to run 14.3 ohms Start to common 12.5 ohms Run to common 2.5 12.6 amps start on common wire 6.4 amps on start on start wire. Compressor seems to get really hot in a short amount of time. Link to comment Share on other sites More sharing options...
AZVendor Posted June 29, 2018 Share Posted June 29, 2018 (edited) What are your running amps? It sounds like it's a bad compressor pulling too much running current. Edited June 29, 2018 by AZVendor Link to comment Share on other sites More sharing options...

I will check on the running amps tomorrow. Do you know anyone that has these decks for sale? Wittern only refurbishes these now, no more new ones.

NYCandyMaN Posted June 29, 2018 Share Posted June 29, 2018 maybe out of freon? off the topic, do you happen to have any extra boards for the cb300? Link to comment Share on other sites More sharing options...
Vendingnewbie Posted November 1, 2018 Share Posted November 1, 2018 Do you know if the CB300 is credit card capable? Beside the compressor issue, has it been a dependable machine? Link to comment Share on other sites More sharing options...
Snack Man 2000 Posted November 1, 2018 Author Share Posted November 1, 2018 They are very good machines. I have sold lots of them, and the issue was a bad filter dryer. Changed it, and charged it, and it's still running strong. They are MDB so they are card reader capable. Link to comment Share on other sites More sharing options...

Otherwise, it is a very capable machine for its size. 2 Link to comment Share on other sites More sharing options...
