Door spring doesn't have enough torque to open the door
I've got a Sharp Carousel R-530 EST Microwave with the door that does not open when I push the open button. When I push the open button, I see the switch lever working and it looked like the spring was missing. I have ordered the door spring but when I put the spring in the middle piece of the open button, it doesn't have enough torque to push the switch lever up to open the door. Where is door spring supposed to go in order for it to have enough torque to open the door? Any help would be appreciated. Thanks.
