The microwave operates fine...problem is the springs at back of button that open door came off. i purchased new spring but can;t get it to remain on back posts after opening the door with it.
For model number LRM1250W

Hi Darlene, Thank you for your question. I would suggest taking a look at those back posts and seeing if they are also broken or not. It sounds like they may be and that is why you are having an issue installing the new spring. Good luck with your repair.

How do I install the spring that holds the push button door opener?
For model number LRM1250W/01
PartSelect logo
Hello Darlene, Thanks for your question. You will want a service technician to install this part as the door contains shielding components. The technician needs to test the microwave for any leaks in the shield before you use the microwave. I hope this helps.
