I could not find any info on the given model number tried here and the Whirlpool site. Please check it.

Some handles have plastic inserts that pop or slide out to let you get to the handle bolts. Sometimes you have to remove a plastic end cap and thjen the insert will slide out.

Others are held by clips on the fridge door. To get the handle off you pull the handle up. Then tighten the bolts in the handle a little and reinstall it onto the clops. Be careful so you do not scratch your door.
