Yes, those are ceramic caps. They should have numbers on them so that you can get the right replacement. I've got a circuit board for a garage door opener, and there are burn marks under a couple caps like that. Haven't looked for parts yet though.
 
Through hole ceramic capacitors generally have a three digit code (surface mount ceramics don't seem to be labelled at all :( ) . The first two digits are the first two digits of the value and the third digit is the number of zeros to add to get a value in picofarads. So for example 224 would be 220000pF or 220nf.

Of course there is no gaurantee that the two capacitors are the same value and I highly doubt the code will be readable on a capacitor that is burnt up like that.

Also it is VERY unusual for a ceramic cap to just fail. It wouldn't surprise me if there is another underlying fault causing the cap to burn out.
 
Yeah...I don't see any markings on the ceramic caps..that is why I am asking..

I am clueless on where to go now..
