How to Fix a Microwave That Will Not Close Properly

If your microwave door won’t close or won’t latch, it usually means there is an issue with the door latch assembly. The latch assembly typically has two hooks which link to the switch holder on the frame of the microwave. When the hooks work properly, they engage the switches to begin powering the microwave, so having them in working order is important. The latch assembly is spring-loaded to provide the necessary tension to engage the hooks.

How to inspect a microwave door latch assembly:

1. For safety, disconnect your appliance from the power source before beginning.
2. Locate and remove the door latch assembly. It will be found behind the inner door panel.
3. Visually inspect your door latch assembly for any signs of cracking, wear, damage, or discoloration.
4. If you find any of the above while inspecting it, you will need a replacement door latch assembly.

If your microwave door won’t latch or is not closing, it may be because of a broken torsion spring. Luckily, this is an easy problem to diagnose and repair yourself. Torsion springs are used to keep the microwave door closed on units with doors that open downwards.

How to inspect microwave torsion springs:

1. Similar to other inspections, unplug your microwave before beginning.
2. Most models have two springs, one on either side. Begin by removing the door panels in order to locate the springs, they will be at the bottom of the door.
3. Visually inspect your springs for any signs of wear, corrosion, or damage.
4. If you identify any issues during your inspection, you will need replacement torsion springs.
