Trouble Codes / Error Codes

I tried to use the search function to find the trouble codes. I could not find anything so I thought we needed a thread for just the Trouble Codes. I unplugged the thing that @rabtech was talking about at the back of the motor and got this code ( O 660 15 ) with a 5 under it. So far with about 6 restarts it has not reset.

It did finally reset after about the 12th time.
