Cold hot water rad

Twice in one day . The entire system works , well , all but one rad . Not air bound , just cold . All I can come up with is maybe a bad charge in or a bad extrol tank . Any suggestions . First house single floor longest run ,forced hot water , got the call no heat in the back room.System has been in and running for 4 years . Second house 2 nd floor,forced hot water . Said all was find till repair was made , Building was drained to repair leak .
