I have a GE gas range Model #JGBS20DEM2WW Serial # HR119397P, The oven door handle broke, so I need two things. 1) how to remove oven door? does it have hinge locks? what angle do you hold door at?Do you pull up & out or just up or just out? does the the hinge come off with the door or stays with the oven? 2) how is the handle replaced? do you take outer door off then...? Please help !!
