Great advice and ideas from everybody, but I am still banging my head into the wall. Here is a time line of replacement parts in this panel:
6/03-- 1st new contactor. Lasted 1 week
6/03--new coil kit. GE warranty. lasted 5 minutes
6/03--new coil kit. GE warranty.
8/03--new contactor. GE Warranty
2/04--new contactor. GE Warranty
6/04--new comtactor. GE warranty
1/05--new contactor. GE warranty
9/05--new coils. GE warranty
12/05--new contactor. GE warrant
8/06-- new coils GE warranty

I have had GE involved in this since June of 2003. They have sent field techs and checked out the building electrical system and found no problems. I can't really see the sending me this many new parts under warranty if they didn't have a known problem with this contactor.

e57, I would love to install a new lighting panel and it has been suggested to the customer more than once. I can't get them to do it yet. Anyway, thanks for the advice guys. I will let you all know what the "new field tech" from GE comes up with today.
