Does your unit supply the full 12V as soon as you turn the knob a third of the way? Or is it gradual, like it should be?

In the first half of the turn it can go from 0V-11V in the increments of 0.3V/0.4V , the other half is 11V-12.2V in increments of 0.1V.

J. hit the nail on the head. Though, my unit is slightly different in that at half way the voltage sits at 11.2. I will say that the touchy scale in the first half of the knob's range can be slightly annoying if you want a mid voltage, but I find it to be a minor inconvenience and am extremely satisfied with the quality and features of the Lamptron FC5V3

That one stumped me too. Nothing in the instructions, although they do mention 12 VDC for that wire somewhere in a diagram. The instructions were horrible, and the thing never powered on. I returned it and got a refund. My suggestion is you do the same.

This is probably too obvious and may not be helpful, but you need to adjust the current as well as the voltage. When I first started using this power supply, I had a similar concern, but found that adjusting current before voltage helped. Sorry if this is not helpful.

Hello, Mine is off on zero and highest on 5... and that is correct. doesn't sound like your knob was put on properly, the arrows line up.... hope this helps...

You have to have your "load" connected first, otherwise the amps will remain at zero. By load I mean whatever it is you're trying to power. First connect your load, then turn the voltage all the way up, turn the amps all the way down, and turn on the power switch. Then slowly turn up the amps, then slowly turn down the volts to desired volt settings. Again, you have to have connected whatever it is you're trying to power to power first. I know, it doesn't make sense, but that's how it works. It threw me for a loop when I first got mine too.

Hi Willa,depress the knob counterclockwise to IGN and when the heater lights then turn to one of the 3 settings; IGN if you want heater to be able to easily light the next time, LO if you want medium heat, and HI if you want the full capacity of the heater. Works well for us.Hope that helps, Fondly, Richard

i Manually turn the knob to where off is written. But the light stops glowing after minutes of turning it ON when steralization is done.So i consider that as an indication and manually turn knob back to off. But havent seen it going to off ever like it would in say a dish washer or rice cooker

Not sure why, mine turns fine. Did you turn your nossle itself slightly to make sure it has a good connection in the wall and turn the on/off button on the handle to on??

Yes, and I asked my Electrician and he said this was normal. I do not know if this is true but I took his word for it. You might want to check with GE

I did. Its hard to explain,but as you adjust knob for speed control your changing volt in a way.I had 24 volt. DC going In an it ran a 12 volt DC motor with no problems.

This didn't happen for me. It could either be a faulty meter, or it is getting 0.0 volts.

Thats not right. Mine works amazing. Im no electrician, but it sounds like a loose connection in your wiring.

This has never happened to me. I just checked the knobs and they work as they should. Hope this helps. Thanks, Brigida

The way to check it with a meter, is for continuity, not voltage. Put your meter on OHMS and check between the battery neg post and where the cable attached. You will see it reads "Open" when the knob is turned clockwise to loosen it. When tightened the connection is completed and you will have continuity "0". Proven that no electricity will flow with the knob loosened.

I agree with T. Thomas, sounds like reversed polarity - it's easy to do as the documentation is not very clear on the wiring.

Mine worked immediately. Perchance is the voltage switched to the opposite curent?

As with most voltage converters, it only activates with a draw on it. As for me, mine is fused and switch controlled, just in case.
