Looks like your overload relay caused a small fire

[hipsterdaddyo]

This is a Humiditrol for a Pool area at a sports club. The blower motor shorted, and caused the overload relay to burn up. Which in turn caused a "small" fire in the electrical compartment. This was a fun one. I'm one and a half days in on the rebuild so far. I will post pictures when I'm complete with it. Just wanted to share the destruction pictures primarily.

That's obviously some kind of retrofit and not a very good one at that. I would have been embarrassed to leave such sloppy wiring in any unit. I think you did them a favor. Somebody or something let the smoke out. You put it back in, awesome job bro!

Beautiful repair, man. That's a quite a bit of wiring you've done, nice and neat too. Good work.

I did a burnup rewire on a makeup air unit on a massive Bingo building roof in -20F with 30mph wind. Much less wiring damage but I'd do mine over again to avoid what you had!

Nice job!

Great work. I honestly would not know where to begin with that. I honestly do know that I would not want to get that bill though.

OMG! I'm going to have nightmares tonight that I was your helper and you just went away...

Looks great. Wait! Where are you going!!!???

Small fire? Yikes! Nice work on the rebuild!

looks dam good to me! i had a similiar situation but not as bad like a year ago but i rewired with all black mine was blaaah. but after seeing yours im curious was it under warranty? and if so do they give you the wiring also i noticed there were alot of pink wires or did you pick up a roll somewhere if i remember right lennox likes to use the pink coloring?

I felt like retrofitting the unit to a 90's era lennox with all the red wire haha. I picked up a roll of red to make up for what I could not get of ready made wiring harnesses from Lennox. I'm still waiting on about 6 of the low voltage wiring harnesses for the A55 and add on boards. Once those come in, I will continue on this project. It's been a lot of fun running all the wires. I definitely learned a lot knowledge from this one. Yeah, in their new units the primary color code is pink yellow and blue.

Nice rewire. Looks real nice.

Wow, that looks really good. About how much time did you have in it?

[deerwhistle]

Aside from the beautiful repair job, what I see is typical, useless/dangerous off-shore or South American components. Years ago a line current carrying part stood a decent chance of containing a major failure. No more although it is good for business. I always liked getting these jobs, the end result if it looked like this one was so very satisfying. Well done friend, this is how a professional does it.

I recall another unit fried almost as thorough as this one and it was a direct, solid lightening strike. It had a few burned wires too.

Nicely done looks like it was a mess but now you wouldn't have known it had a melt down

What's the alternative? I haven't found an American made contactor. All China. We could at least get Mexican built until Furnas sold out to Mars...

The rebuild looks good, though.
