We recently had our SWG stop generating and none of the colored lights on the control panel were lit. I searched online and found an old thread on this website that accurately described our issue and the recommended fix. I've looked through the website before and found it very helpful, so I decided to subscribe. Any way, the "fix" was a $2.50 resistor from digikey.com. I ordered 2 and with shipping it was less than $11! We were able to swap the part and once again the unit is working! This sure beats the expensive alternate of ordering a new control board. This website is invaluable. Thanks for sharing all your knowledge. The link to the original thread with the part # info is below.
