Thank you for using Just Answer.
I don't think that you should keep the unit plugged in or use it because you may damage the 3rd board that you have just installed.
You may have a problem with the wiring harnesses or another component. I have the repair manual at home (I"m at now) I can upload it for you later tonight after 9:30 pm if you can wait.
Let me know if that would be ok for you.
I've uploaded the repair manual.
When you go to the site to download do not use AOL. Use Internet Explorer or another browser because that site does not like AOL. Choose the "Free" option. After you download the file you will need to open it with Adobe or another application. You should already have that on your computer.

I'm sorry the download didn't go smoothly for you.
The PDF file is much more than the schmatics. You should download it.
We use that site every day. It can sometimes be tempormental! Don't give up.
Clean your temporary files and hard drive. Turn your computer off afterwards. When you turn it back on, go to the site right after you log to your browser (Internet Explorer seems to work best).
You should wait until the file completely downloads before trying to look at anything. This could take four or five minutes depending on the speed of your conncection.
Download the file to your hard drive and choose "save" from the top of the PDF tool bar to save to your desktop (or somewhere you can find it easy).
After you download the file, you will see that it is worth the extra effort because the troubleshooting diagnositc steps are laid out there. It shows how to test components to confirm what is bad.
The mult-meters are around $20.00 or so and you can them at Home Depot or Sears. They're handy and you need them when checking any appliance. They will save you from buying expensive components that don't fix the problem.
This link has very useful information on how to use it.
Always disconnect the machine and one side of the part when testing for ohms. Be very careful when testing for voltage and set the meter correctly (voltage AC).
Post back to this question if you need more information.
