door won't go down

My sisters garage door opener works fine when going up but will not go down unless you hold the hard wired button for the full length of travel.My brother-n-law went to trouble shoot it and broke one of the sensors I'd like to defeat the sensors and test the opener , for all I know there's a bad relay on the board somewhere.Are they N.O or N.C . down force is set for 3kg

They have designed the GDO so you can't wire by the sensors. Most likely the sensors were bad or there was a broken wire going to one. The sensors are not hard to replace and can be purchased at your GDO dealer. The sensors are a good safety feature and are required by many building codes.
