new LC1390N (80 watt) that completely lost power- in machine gfci flips it off

[Sonja Pete]

Hi
I have a brand new LC1390N (80 watt) that completely lost power-
the in machine gfci circuit switch- or the "master switch of power supply" in the back of the machine immediately flips it off when plugged in.
I going to replace the fuse right next to the main power in the back? I have replaced the power supply and it still does not power on.

so- I am doubting the fuse is the issue- but will replace tonight,

trying to narrow down my problem- worried it is a short somewhere in the machine - if anyone has any thoughts- much appreciated!
thanks
Sonja

Are you using the chinese made extractor plugged in to the rear sockets, also are you using a chinese water pump in a tank of water plugged into the same?

Hi Dave,
nothing is plugged into the back. THey are all on separate power. I have a CW-5000 chiller.

Check that your 220V wires are attached properly to the power supply. There are two ways that I have seen it done with different power supplies. If you need pictures I'll send later.

The Fuse is not a problem if it is not blown. But DO NOT PLUG ANYTHING INTO THOSE SOCKETS!
THEY ARE WORTHLESS!
Plug ALL, ALL, not just some, but ALL accessories into their OWN outlets and power Nothing thru those sockets on the back of the machine!

Am I clear enough?
Sorry, but second time this week!!!!!

Thanks John, nothing is plugged into the back, thankfully had that advice early on.

Hi Joseph,
mine is a 120V but pictures would be great,
I am not plugging anything (water chiller, etc..) into the back of the machine to power- they are all on separate power strip and power.
much thanks for any pictures or advice!

Sorry so long to reply. Been away. If you are 120V then just be sure that the ground wire on the back of the Power Supply is in the right spot. Actually, you might try switching it around. But if GFI is not bad then maybe try flipping them. Otherwise I have nothing.

Also- this machine has yet to work for me- It has not powered up since out of the crate.

Sonja,
Are sure it is set up to run on 120volts?? With an 80 watt tube I would guess it is set up to run on 220v.

Hi Scott,
When ordering this model one can request either 240 or 120, I chose 120 as someone I know has one at 120;
There is a 2nd power box (conversion? box) inside that has a switch that says 115v or 230v - it is on the 115v. I will upload pictures. thanks!

Sorry for the rant and assumption! Interesting that it is switchable, there is usually a fuse, but if switch is kicking off, it might possibly be either wired wrong, or the switch bad. Switch shouldn't kick off if fuse is blown. If you already have replaced the power supply and the fuse not blown, I'd almost say you have bad switch.

From a electricians view point either you have a short or ground inside the machine or a defective CB and are you sure its a circuit breaker or GFI? I do not see a factory installed GFI very often unless its on for example a hot tub.

Unless you have access to a clamp on amp meter, the other way is to with the power off start disconnecting wires to power supplies or devices inside the machine, one at a time and try the switch again. Take pictures of the connections or mark wires in a way you can re-connect the right way.

The other thing, the Chinese do not really always have grounded outlets like we do here. That is why they supply an extra ground wire and connection to the machine. They might have that connection crossed with the power in.

I have seen people tie the white and green equipment ground together..... not Code for sure! If someplace in your house wiring they have the white and black (hot wire) crossed, that would do it!
