lxkev Posted October 28, 2016 Share Posted October 28, 2016 Had an Antari low fogger give up on me. It's not pumping, have replaced the pump and still no life in it. The voltage to the pump when activated is only 20 volts when it should be 230ac, Anybody got any thoughts on how to fix it? Thanks Link to comment Share on other sites More sharing options...
Don Allen Posted October 29, 2016 Share Posted October 29, 2016 Is there a resetable thermal switch in this model ? Link to comment Share on other sites More sharing options...

ThanksI have no experience of this particular machine but some have an opto-triac to control the pump. This is a six pin DIP with an LED driving a small triac. You should see about 1.2v across the input (usually pins 1 & 2) if it's being switched on. If you've got that and still have mains voltage across the output pins (usually pins 4 & 6) then the device is faulty. BTW pin 5 is often missing.Dave E.g.

lxkev Posted October 31, 2016 Author Share Posted October 31, 2016 No thermal switch, I've replaced the traic which made no difference. Have found an opto-triac to control the pump 3023. Will check meter readings cheers Link to comment Share on other sites More sharing options...
