hoover condenser hnc382t not sensing

Hi I have come across a Hoover HNC382t and at first it wouldn’t compete a program aswhenthe start button was pressed it would run for 5 minute then stop so i replaced thecontrol board and it solved the problem. But now it doesn’t dry things properlywhen usingthe sensor dry settings although customer is also saying that it doesn’t dry properly on the timed setting but I ran it and seemed to get to the correct temperature onboth timed and sensor. Have ordered a new sensor which I see is in the lint filter bit sowhat Ialong is could sensor be faulty? And if so how do you get to it to replace it as can’t see where the front comes apart

Thanks Graham
