CECAA850 Posted November 9, 2009 Share Posted November 9, 2009 Can anyone tell me what this is? It's about 5/8" long. It's actually light blue in color. The rings are gold, red, black and gold. It's off of a PC board in a boiler. If you know what it is, can you tell me how to test it and/or where to get another one? Thanks, Carl.

Arkytype Posted November 9, 2009 Share Posted November 9, 2009 Carl, Chances are the first band is brown, not gold. The value is 1,000 ohms and the tolerance (the gold band) is + or - 5%. Based upon the color and shape, it looks to be a wirewound type. From the size it could be a 1/2 to 1 watt rating. Do you have a way of measuring the resistor? Here's one of many on line resistor calculators. http://www.dannyg.com/examples/res2/resistor.htm Lee Quote Link to comment Share on other sites More sharing options...
CECAA850 Posted November 9, 2009 Author Share Posted November 9, 2009 It measures 1004 Ohms. The gold bands COULD be brown, but they really look gold. Maybe it's the light blue background they're on. Quote Link to comment Share on other sites More sharing options...
CECAA850 Posted November 9, 2009 Author Share Posted November 9, 2009 I guess it's brown, black, red, and then gold. If that's the case then this resistors not the problem with the board. It's the only spot on the board that looked like it got hot and was discolored. The board is 300.00-400.00 dollars, I thought I could get lucky and find a bad part as opposed to replacing the board.

Don Richard Posted November 9, 2009 Share Posted November 9, 2009 It's a 1K, 5%, flameproof resistor. This type component is used when heating is expected, thus the charring on the PCB beneath it. There is probably an active component that has failed. If those are socketed on your board it would be possible to easily swap them out for repair. If not, then it is a board level troubleshoot and repair job. You may need to send this one to the shop. Quote Link to comment Share on other sites More sharing options...
CECAA850 Posted November 9, 2009 Author Share Posted November 9, 2009 You may need to send this one to the shop. Unfortunately there's no shop. It's a "replace the whole board" option unfortunately. Quote Link to comment Share on other sites More sharing options...
JL Sargent Posted November 9, 2009 Share Posted November 9, 2009 Let me guess. There are some big ICs on the board too, each with about 60+ pins. Quote Link to comment Share on other sites More sharing options...
JJkizak Posted November 9, 2009 Share Posted November 9, 2009 And they are probably no longer available and the board probably has been re-designed with a new model. JJK Quote Link to comment Share on other sites More sharing options...

CECAA850 Posted November 10, 2009 Author Share Posted November 10, 2009 And they are probably no longer available and the board probably has been re-designed with a new model. JJK Most likely with a new and improved price. Unfortunately, I'll find out today as I call around. Quote Link to comment Share on other sites More sharing options...
JL Sargent Posted November 10, 2009 Share Posted November 10, 2009 You could go wholesale and replace all the caps. Then try it. Replace all transistors and try it. You might luck up and breath life back into it. Quote Link to comment Share on other sites More sharing options...
CECAA850 Posted November 10, 2009 Author Share Posted November 10, 2009 You might luck up and breath life back into it. You obviously don't know me very well. I must have pissed off lady luck somewhere along the way. We don't get along very well. I thought that changing my name from Murphy would help, but no "luck".
