How to repair a microwave door with a broken spot weld

My microwave door slacks down and I have to lift it up a bit before shutting it. I sent this picture to Frigidaire and asked what I should do:

Their support emailed me back saying:

I'm sorry, there is no screw that goes in the hole. that actually is a
broken spot weld for the hinge. The hinge cannot be repaired.

Here's a short video of the issue:

I want to fix the issue without replacing my entire microwave. Anyone have any ideas on how I can fix this?

Best Answer

Don't do it.

Microwaves, while safe, emit a significant radiation that is controlled, in part, by a carefully designed door interlock system. If it is compromised, there is a risk of radiation leakage.

You don't fix microwave doors, you send it back for them to fix or you replace the entire unit.

Period.

SUPPLEMENT

The World Health Organization (WHO) has this to say about microwave oven safety.

Microwave safety: The design of microwave ovens ensures that the microwaves are contained within the oven and can only be present when the oven is switched on and the door is shut. Leakage around and through the glass door is limited by design to a level well below that recommended by international standards. However, microwave leakage could still occur around damaged, dirty or modified microwave ovens. It is therefore important that the oven is maintained in good condition. Users should check that the door closes properly and that the safety interlock devices, fitted to the door to prevent microwaves from being generated while it is open, work correctly. The door seals should be kept clean and there should be no visible signs of damage to the seals or the outer casing of the oven. If any faults are found or parts of the oven are damaged, it should not be used until it has been repaired by an appropriately qualified service engineer [emphasis added].

The US Food and Drug Administration (FDA) says this

Checking For Leakage: There is little cause for concern about excess microwaves leaking from ovens unless the door hinges, latch, or seals are damaged. If you suspect a problem, contact the oven manufacturer, a microwave oven service organization, your state health department, or the closest FDA office [emphasis added].

The problem described is not just tightening a screw or putting a seal back in its track. The door is misaligned and poses a risk. Trying to realign and weld parts of the safety system seems very ill-advised.
