    Inductor Question

    Are you saying that those two components are my likely failure points? The 11n60 MOSFET checks out fine, out of circuit, with a simple MOSFET testing procedure. I don't know which component on that board would be an oscillator though. Here is a picture of the back of the PCB. You can see the...

    Inductor Question

    There doesn't appear to be any visible indication of failure. Here is a pic of one side of one of them. All three are the same.

    Inductor Question

    Not necessarily the cost of a replacement I am working with, but the challenge to fix it. I'm doing the work. And MY time is cheap. :)

    Inductor Question

    Thanks, Delta. That's why I photographed the end cap with the make and model number. I'm surprised, however, you didn't have your crystal ball figure it out for you. :) Yep. The electronics appear to be the same. The housing is a bit different though.

    Inductor Question

    Hi all. I'm working on a US Model 220vac Hot Tub Water Pump that runs 24/7. They last a couple of years and then they just die. I decided to open one up and see what was inside it. According to the information I have read about this thing so far, there are no moving parts, except a...

    Need help troubleshooting pcb relay

    Mack. Take very clear photographs of the soldered side of that board and post them for examination please. Even go so far as to take quadrant photos, if you can, but they need to be clear. Stop messing with everything else until we get those picture please. Cold/broken solder joints cause...

    Help identifying a transistor

    Where Delta Prime and Kellys_eye have pointed out the cold/broken solder joints, you simply need to heat up your solder gun high enough to melt that solder. Add a bit more solder to each one of them until the solder corrects the bad joints. There is another one that is visible in Delta Prime's...

    Help identifying a transistor

    If you aren't familiar with Chevrolet/GM Vehicles in that time period, and the issues they had with printed circuit boards and cold solder joints, today is the day. Take that board and turn it over. Take very clear photographs of the solder connections on that side and post them here. You...

    Need help troubleshooting pcb relay

    Have you checked all of those solder joints? Since you were able to get it working for a little while, because you SOLDERED something, that may have been the issue all along. Check ALL of the soldered pins on the soldered side of that board. If you can take very clear pictures of that side of...

    Need help troubleshooting pcb relay

    So take a look at where Edd has blown up your photo. On your original photo the area is near the bottom right half of your picture. In Edd's photo, the top left. Look very closely at the solder joint where he has marked "Blk Rly's 12v coil" and the pin to the left. Look very closely at that...

    Need help troubleshooting pcb relay

    One thing I think I am seeing on the soldered side of the board are what appear to be cold solder joints, especially in Edd's modified picture in the upper left corner. It may just be the way the photograph was taken, but they can cause all kinds of issues, including problems like you are...

    Hunter Ceiling Fan Receiver

    I am using the datasheet for the BTA08-600C. Pin 1 is A1. Pin2 is A2. Pin 3 is Gate. https://pdf1.alldatasheet.com/datasheet-pdf/view/400722/STMICROELECTRONICS/BTA08-600C.html Attached are photos of the Triac side of the board, front and back. Sorry, but trying to provide you with an actual...

    Hunter Ceiling Fan Receiver

    Hi again, all. Well I was able to source the triac (BTA08-600C) and the zener diode (24D5) and have installed both of them. I also replaced a D882 Transistor that is in the same circuit. I also changed out three e-caps in the antenna section, since they showed an out of range ESR. When I...

    Help me ID Component

    Actual pictures of the PCB and the components attached to it, front and back, is what I was talking about. Thanks for the schematic, though. Since the fuse is in line with the mains in, and you said the problem started after a power surge, I would first check that bridge rectifier (DBL155G)...

    Sogo jpn-650 circuit not working

    For starters, it appears F1 (a fuse) is blown.

    Help me ID Component

    To make your life easier, and to get a better outcome here, you might want to take a very clear picture of both sides of the board with all of the components clearly visible and also supply the entire schematic. It makes it easier for the experts as well. Speaking from experience here. Oh...

    Hunter Ceiling Fan Receiver

    Thanks, Delta. I was able to find another manufacturer's component and have them ordered. Once they arrive, I will be able to tell if it was, or was not, the problem component. I don't see an actual DIAC on that board anywhere, unless I just don't know what I am looking for or at, so I am...

    Hunter Ceiling Fan Receiver

    Well here is one that wasn't answered by Kellys_eye. The circuits from Pin 1 of the Triac had traces that went to different places on the PCB. I followed them with a continuity check to locate exactly where they went. Because I had damaged the pad there, am I able to hardwire each point from...

    Ok. Thank you. I will go away now. More parts to buy. :cool:

    Hunter Ceiling Fan Receiver

    Thanks Delta. So I am still having a hard time locating that specific component. I can find a 2EZ24D5 (https://www.alldatasheet.com/datasheet-pdf/pdf/59666/EIC/2EZ24D5.html) but is that the same diode? It is missing one "2". Mine is marked as 224D5, and if I add the 2EZ to that, I should get...
