The punishment comes after Mourinho admitted a misconduct charge over his language and behaviour in a defeat by West Ham on 24 October.
Mourinho was sent to the stands after going to speak to referee Jon Moss in his room at half-time.
He will now miss Chelsea’s next league game, which is at Stoke on Saturday.
The stadium ban is separate to the suspended one he received, along with a £50,000 fine, for comments he made after a defeat by Southampton on 3 October.
The Portuguese described that fine as a “disgrace” and appealed.
Mourinho’s assistant, Silvino Louro, was also charged by the FA after being dismissed during the match at West Ham in relation to his behaviour in the technical area.
In a statement, the FA said Louro has been reminded of his responsibilities.
