While on Let's Make a Deal, Merrill would model the various prizes, present money to contestants, and perform various other tasks as an assistant to host Monty Hall. On Let's Make a Deal, Merrill was frequently referred to by Monty Hall by her full name, and thus became one of the first game show models to be known as such, rather than the customary first-name-only naming convention used by such shows as The Price Is Right. This allowed Merrill to gain wider recognition than other game show models of the time, and her celebrity status has led to many guest appearances on talk shows such as the Late Show with David Letterman, Good Morning America, and Geraldo. As Hall once put it,
"I never said 'door' without saying 'Carol Merrill.' 'Let's see what Carol Merrill has behind door No. 2.' 'What Carol Merrill has in the box.' So she and Jay Stewart, my announcer, became stars. Everywhere we went, people would say, 'How's Carol?' 'How's Jay?'"
Merrill, along with original Let's Make a Deal announcer Jay Stewart, made an appearance in 1986 on the finale of The All-New Let's Make a Deal, modeling a zonk along with Stewart. After learning that the contestant traded $1,427 for the zonk, Merrill decided to let him have the $1,427 anyway while Stewart gave him a banana bunch to go with the money.
Acting
In addition to her 14-year stint with Let's Make a Deal, Merrill was a model on the short-lived TV seriesYour Surprise Package, and for one episode of the TV series Burke's Law, both during 1963. She also played several other small roles in various films in the 1960s and early 1970s.

From 2001-09, she and her husband, Mark Burgess, lived in Australia before returning to Hawaii.
