Harrington has had a disappointing few years since his last victory at the 2008 USPGA Championship and has previously blamed overpracticing for his slum.
The Irishman is known for his long winded practice regimes and its believed Torrance has told him to slow down.
Harrington admits that he has stopped listening to the coach and says the time is right for them to take a break.
"We haven't split. We are having a break because I am getting very frustrated" he added.
"Until I am ready to listen to what he has to say we are having a break."
