The programme, aired on Channel 4 in May last year, featured Brown following Liverpool psychic Joe Power as he supposedly helped people connect with their dead loved ones.
The show saw Power giving one-on-one readings with women called Wanda and Roz, as well as running a session with several actors from Hollyoaks.
It was suggested that the psychic had prior knowledge about the subjects before giving their readings, such as his sister living next door to Wanda, or guessing rightly that Hollyoaks actress Claire Cooper owned a Mini after seeing her pull into the car park driving the vehicle.
Power complained to Ofcom that he was treated unfairly in the programme and was misled about the nature and purpose of the series before agreeing to do it. He also claimed that the programme makers "presented, disregarded or omitted material facts in a way that was unfair".
However, Ofcom found that Power "was provided with sufficient information about the programme before participating in it" and "clearly understood that Mr Brown was a sceptic". The regulator also found that the readings for Wanda, Roz and the Hollyoaks cast were "presented fairly", with Power given sufficient chance to respond to any criticism.
Ofcom noted that Power was given a full description of the programme's aims beforehand, in which it was made clear that it would have a "sceptical element".
"In Ofcom's view it was likely that, if a programme was described to a potential contributor as having a sceptical perspective whilst viewing paranormal phenomena, that contributor should expect to be questioned, if not, challenged," said the regulator.
"Ofcom also noted that Mr Power had sight of the programme description a month before filming began and signed the release form after negotiations had taken place."
