The toilet is fixed. Called Thetford this AM and they told me a video to watch on their website on how to replace/install a new foot pedal. Took about 10 minutes after watching the video. The video says to remove the toilet. I had my wife sit on it to hold it in place after I got everything lined up. Hit it a couple of times with my hand and we are back in business.
Got a price from Thetford for a new foot pedal, $41.00 plus S&H, $59.69 from an RV dealer and $46.00 from another RV dealer.
Don't know why the pedal came off in the first place. Will see if it holds up, if not will have to break down and buy a new one
