Growliebusters Posted July 19, 2014 Share Posted July 19, 2014 I have a strange request from one client. The combo machine I have there has two fans that run 24/7. I need to somehow have the condenser fan only run when the compressor is running. I'm thinking a relay that is tied to the compressor start switch is the answer just not sure how to go about that. Don't really want to hire an expensive tech if I don't have to. Any ideas? Link to comment Share on other sites More sharing options...
AngryChris Posted July 19, 2014 Share Posted July 19, 2014 I would simply say that it's necessary for proper refrigeration. Link to comment Share on other sites More sharing options...
AZVendor Posted July 19, 2014 Share Posted July 19, 2014 It sounds like you are describing a Seaga Office Deli machine, or a similar model. I don't know why they wired the condensing fan that way but it may be for better cooling of the Korean compressor between cooling cycles to lengthen it's life. You will have to understand the wiring of a compressor in order to change this. What I can tell you is that you could tap into the compressor side of the 110v wire from the relay for the switched leg to the fan. The other leg of the fan circuit will have to go to a junction of neutral lines that should be in the wiring near the compressor. That's the best I can do. The fan that is on the condenser doesn't use much electricity. It's a shaded pole motor that used .35 amps (note this is (point).35 amps, not 35 amps) at 5 watts, so it hardly uses any power. The other fans are on the evaporator and they will always run as should all evaporator fans. Link to comment Share on other sites More sharing options...
snack dude Posted July 20, 2014 Share Posted July 20, 2014 my first question would be, "why? does the customer request this, Is it noisey? Do they think they are saving electricity? I am with chris on this one, Do they like cold stuff thats suppose to be cold to come out of the machine. Link to comment Share on other sites More sharing options...
Growliebusters Posted July 20, 2014 Author Share Posted July 20, 2014 AZ you are correct, it is a Seaga combo..The reason is that the fan and cheap golpher cover make quite a lot of noise. I've been able to eliminate most of the vibrating noises but the fan is really noisy. This is in an office that is surprising quiet for a manufacturing plant. Its not the end of the world but I would like to accommodate if possible. First 4 weeks there have grosssed almost 500 and I even added a bill validator that's being used a lot. This is an account I really don't want to lose. Link to comment Share on other sites More sharing options...
AZVendor Posted July 20, 2014 Share Posted July 20, 2014 If the fan is the reason for the vibration then you should replace it. That way you don't need to mess with wiring. If you remove the front grill and the vibration stops then maybe the fan motor is okay. Do you hear the vibration when only the fan is on or only when the compressor is on?

orsd Posted July 20, 2014 Share Posted July 20, 2014 get a decnt machine Link to comment Share on other sites More sharing options...
Growliebusters Posted July 20, 2014 Author Share Posted July 20, 2014 No grill, its cutouts on the side of the wall. The fan is just noisy. I have 4 of these and they are all noisy by design. orsd: unfortunately I got caught in a biz op and am stuck for now. I am going to make this business work, failure is not an option. That said, looks like I'll be buying my first used machine next week, NOT A SEAGA. Looking forward to that. Link to comment Share on other sites More sharing options...
AZVendor Posted July 20, 2014 Share Posted July 20, 2014 If you have the condenser mounted on the left side of the machine then that fan motor should be off when the compressor is off, unless someone has replaced the compressor before and wired the fan wrong. This sounds like an HF3500 model. Link to comment Share on other sites More sharing options...
Growliebusters Posted July 20, 2014 Author Share Posted July 20, 2014 LOL you know your stuff. Its a VC630 a Canadian version of the HF 3500. The condenser is on the left when looking at the front of the machine. Compressor in the middle and the evaporator is enclosed on the right. Everything is mounted on a deck.that is easily removed for bench testing and repair. I've managed to stop most vibration noise. Link to comment Share on other sites More sharing options...
rmorris1953 Posted July 20, 2014 Share Posted July 20, 2014 You might try to find a fan blade with more blades... Or maybe you have bent the one that is there. Sometimes they get bent and need to be replaced or straightened... Link to comment Share on other sites More sharing options...

I'd have about 9 full size refurbs for the price of 2 Genesis junk, compost machines. It's sad.I hope all the NEW vendors learn from us and avoid combo junk at all cost. I'm still running one that can't handle the volume where it's at. Board is on it's way out. I'm just waiting to part it out, as it's still vending.

Growliebusters Posted July 21, 2014 Author Share Posted July 21, 2014 Yep, looks like they'll have to live with it. I've done all I can realistically do. Not paying an electrician and I don't know if I shoiuld start messing with 120 volts. Do something wrong and it'll really gopher up your day.
