Problem with CTB16D!!!

Recommended Posts

Ok, so yesterday my LOR was working fine, today it didn't turn on. Breakers were all fine everything. So I figured I would check the fuse. What I found was extremely disturbing. I immediately flipped the power disconnected everything and brought it all inside!

I have no idea what happend. I am assuming some water got to it.

From the right hand side fuse clip the furthest right side, there is a burn mark all the way to the wire block. The wire block right at the area is is slightly melted and the wire connected to it has burn marks. I moved all the wires and on the other side of the wire block, there is a screw holding the board to the heatsink and it has burn marks aswell, including around it on that side. After taking out some things (fuse, which seems fine, wires etc.)

I discovered that the area where it is burnt is actually ate through the green layer (Or it appears so) And reveals a rusty looking metal (Copper Clad??) I am so scared right now..
Just want to crawl in a hole and die!

I havent been able to get good pics of it, I think I will take a video on macro and see if it works better....

Omg...

(Chris Farley look)... What did you do?! I got to send a board back to Dan still that had a transistor burn where it connects to the board.

Settle down Zac, your subject line sounds worse than it probably is. As you probably know by now, Dan stands behind his products if it is a defect. Try contacting him before flipping out too much more. We are here and if needed, Brad will give you a hug! :) Everything will be ok.

I am just really worried cause there is a kind of depression wherwe the burn is it like burnt a hole in it! It is also burnt on one of the little white 6 legged things, just slightly. I dont know why it didnt filp a breaker.

I don't think this is a defect. It looks like water got to it.

I am uploading a video right now, i dont haqve a macro photo camera...

1 minute...

Zac,

Just send the card back to us at LOR. We need to see the card. Pictures will not help us to understand what happened. It could have been water in the box or any number of things that happened.

Simply put, this is the custumer service that I have watched from LOR that has me set to be a major LOR buyer/user!

If Dan would send me my software I could get to work instead of lurking around PC:D

Well, I will send it back and the funny part is, I am going to get Dan to hold the fixed board until my next order LOL... Shows how good his customer service is...

Zac,

My guess is that you had a loose cord in the wire block. If cords aren't tight, they heat up. Now if it appears to have come from the fuse instead, it could have been a loose fuse, or a bad solder joint at some point. Hard to tell from your pic.

EDIT your video doesn't work for me -- comes up as a text page.

I had to "save target as" to see the video. It is 74MB. It does show things much clearer but still cannot say what happened. There were a couple of frames where I could get a good look at the other fuse holder on that side and it does not look like a complete solder penetration on it BUT only the bottom trace was being used on the involved fuse holder so it is impossible to say.

As I mentioned there are a number of things it could have been... When we get the card we can take it apart and then see if there was any problem with the card. In any case we will take care of Zac.

Got it working with the save-as trick. Since there are burn marks on both sides of the term block, I'd guess the problem originated there, not with the fuse. But as Dan said, you'd really have to inspect the board. I'd be curious to see the underside also.

The underside of the board is acutally fine... I think....

Try to tighten the screw connections in the neighborhood of the burn. Any of them loose?

Our furnace died in our old house. Upon lots of diagnostics, I traced it to a loose neutral in the main breaker box. The wire had chared so badly that there was on insulation for about 4 inches. Thankfully there was plenty of slack and I just trimmed it, and put it back in VERY tight.

zac you posted this pic in the offical encloser forum. it shows the power wires exsposed. this could of been your problem with this board they may have come loose. also you may want to hit the ends with a little solder it seems to help hold the wires in place better.

We had a similar problem like this on our boat. One of the wires connecting to the shore power plug had corroded (it wasnt tinned). It burned the connector and melted the cord. You may want to check to see if the wire was corroded. It would have had higher reisistance and more heat.

Zac, I watched your video and it looks like it arc'd... It also looks like you're using #14 THHN solid, right? Not sure that tinning solid wire is necessary, is it for these? *edit* I guess maybe to hold the wire in place yeah... /*edit*

Be sure that after Mr Dan fixes you up, when you re-wire it, make sure that the insulation is covering everything that needs to be covered... It looks as if you may have pulled a little too much off there... That one wire, next to that board screw worries me... JMHO... :)

Actually the damage was not even near the power wires. I don't know what happend everything seemed to be tight...

Zac

P.S. the board is all gone now off to Dan so I can't check it again.

Buynow:

it shows the power wires exsposed. this could of been your problem with this board they may have come loose.
