Rockytime Posted January 29, 2018 Report Share Posted January 29, 2018 Looks like my $200 Hawk will be a $350 Hawk. I pulled the controller. The pot and switch are OK. Current flow is stopped somewhere in the pc board. Tomorrow I will switch controllers with the older Hawk for a dynamic testing to see if the controller works on the older saw. That will be the final test. If it does not work on the older saw I will have to spring for a new controller. Darn! OCtoolguy 1 Quote Link to comment Share on other sites More sharing options...
Dan Posted January 29, 2018 Report Share Posted January 29, 2018 Not many components on the board. Can't you fix it? OCtoolguy 1 Quote Link to comment Share on other sites More sharing options...
Rockytime Posted January 29, 2018 Author Report Share Posted January 29, 2018 Not without a schematic. Someone with electronic experience could possibly but that's way beyond the scope of my intelligence. Many years ago, perhaps 60 or so, I used to do TV repair. I know nothing about solid state. But thanks for the suggestion. OCtoolguy 1 Quote Link to comment Share on other sites More sharing options...
DME72 Posted January 30, 2018 Report Share Posted January 30, 2018 if you go to a good electronics parts supply place they should be able to help you or know someone who can. most of those parts are only a few dollars, just have to find out which one.

Rockytime Posted January 30, 2018 Author Report Share Posted January 30, 2018 The switch tests good. The pot functions as it should. There is continuity in the power cord to the pc. There is no current going to the output cable so the problem is in the pc board. I have no way to diagnose it. OCtoolguy 1 Quote Link to comment Share on other sites More sharing options...
DME72 Posted January 30, 2018 Report Share Posted January 30, 2018 based on the qc4100 number it looks like it was made by quantum controls of MN. dont know what they cost but i am pretty sure they can point you in the right direction as to what might be wrong.

Rockytime Posted January 30, 2018 Author Report Share Posted January 30, 2018 Won't they need to have the board in hand to test it? OCtoolguy 1 Quote Link to comment Share on other sites More sharing options...
DME72 Posted January 30, 2018 Report Share Posted January 30, 2018 call them up and talk to one of the people in service or find a rep in your state. they still list that exact board on the website.if you have some basic troubleshooting skills they can probably help you pinpoint what is wrong.

Rockytime Posted January 30, 2018 Author Report Share Posted January 30, 2018 I have difficulty on the phone because I am hearing impaired. Perhaps I can have my son-in-law track them down. If I can locate the board I can certainly install it. Most everything is plugged in with just a few solder joints. Thanks for the information.

And a visual inspection of the pc board should show you if there is anything burned or cracked. Don't give up on it without at least letting someone who knows what's what to take a look at it. Exhaust all avenues before plunking down the cash. Does the saw run at all? Maybe the rocker switch is bad.

Rockytime Posted January 30, 2018 Author Report Share Posted January 30, 2018 I've looked carefully at the board and see nothing suspicious. I have not removed the board to inspect for circuit breaks. Don't think I will do that. OCtoolguy 1 Quote Link to comment Share on other sites More sharing options...

But, like someone else said, I'll bet if you took it to an electronics store someone there would be able to maybe put you in the right direction. I'll still bet it's something simple and cheap.

Dan Posted January 30, 2018 Report Share Posted January 30, 2018 From what you described, if nothing looks or smells burnt, it is most likely the chip. If you can get the number off the chip you can probably pick one up (or order online) for less than $10. I can point you to some reliable sources if you choose to try to repair the board. I would still call the company first as Ray suggested. OCtoolguy 1 Quote Link to comment Share on other sites More sharing options...
OCtoolguy Posted January 31, 2018 Report Share Posted January 31, 2018 Len, I just took the picture of your controller and brought into Irfanview. I rotated it 180 and zoomed in on it to try to see more of the pieces and parts. To me, the solder joints on the potentiometer don't look good. Is there a possibility that there might be a "cold" joint on the red wire? It just doesn't look good to me. It should be a smooth shiny flow of solder and from what I can see in the pic, it doesn't look that way. I'd sure like to see the underside of that board too.

Rockytime Posted January 31, 2018 Author Report Share Posted January 31, 2018 I have decided to purchase a controller. I can make much more money repairing a clock and in less time than I spend with the controller. I do appreciate the input from each one of you. What a great group. Were it a simple and quick fix I would do it. The simplest thing is a defective pot or cold solder joint but that is not the case. kmmcrafts and OCtoolguy 2 Quote Link to comment Share on other sites More sharing options...

Dick heppnerguy I'm one of those people who absolutely hate to throw anything away if there is the remotest possibility of fixing it. My wife's washer was making a noise so I called a repair guy. He told me that we should trash it and buy a new one because it would be a minimum of $400 for him to service it. I once again went to youtube and found a video. Everything is repairable in most cases. Ray Quote Link to comment Share on other sites More sharing options...

I know that does not cover all things, but the majority of them.. like washing machines.. It is the new electronic boards that keep me away from trying to repair most things any more...They seem to be something that is expensive to buy and unfixable for the average lay man.

Dick heppnerguy And you would be oh so correct. But, when it comes to making a noise when it shouldn't, that is usually mechanical so fixable. We have a service contract right now that is good for one more year. Then we will let it go until we need it again. The last time we had a issue that I wasn't sure how to fix, we called the service guy out and he diagnosed the problem as the door lock interlock. Electronic and mechanical. He told us how much to fix it but at the same time, he offered to sell us a two year service plan that would cover the repair and cover us for the next two years for not much more. Well it was a no brainer to buy the plan. He fixed the problem, supplied the parts and we were covered for two years. I'm sure that the next time it happens, if we are out of contract, we'll be offered that same thing again. At that point, we will have to figure out if we want to renew or buy a new washer or pay to fix it. Whatever works. R Quote Link to comment Share on other sites More sharing options...

Which way to go. after you put almost as much into an item and a new one would cost it becomes time to move the new, Dick heppnerguy OCtoolguy 1 Quote Link to comment Share on other sites More sharing options...
Dan Posted February 2, 2018 Report Share Posted February 2, 2018 Somehow, my mom's furnace started making noise. Long story short is the plastic fan blades had broke causing vibration. It was Saturday and the local part store was closed. It was a $35 part. Mom wanted it fixed that day and ended up costing $280. I cringed!
