The actress played the iconic role of Bet Lynch for over 25 years until 1995. She has made several brief returns, most recently in November 2003.
"I'll never play her on screen again. I'm in a position where I've worked hard so I can pick and choose what I do. I don't want a return to the spotlight," Goodyear told the Daily Star.
"Fans ask me about Bet every day but I want to leave my legacy as it is. With quantity you lose quality. And I'm a perfectionist. I have done 25 years and more than 2,000 episodes. The schedule now is so much tougher than when I was on it."
Speaking of meeting fans, she added: "Because people feel they know me, they don't feel like they're meeting an intimidating character. The public sees me as a friend.
"Bet was everybody's friend, sister, mother, auntie. I always have time for fans. They're the ones who put me there in the first place."
Goodyear finished seventh on this summer's Celebrity Big Brother.
