Mopdel # R-1481 m: door latch doesn't work - Sharp R-1480 Microwave Oven

Check those 3 micro switches in the door latch assembly

Can you move the latch in the door? This is spring loaded, maybe the spring is broken

You have a faulty door safety interlock switch. I wish you would have searched your problem here before you spent all that money on the magnetron. I have answered this question dozens of times here at this site.

When the oven runs but doesn't heat, more often than not it is nothing more than a faulty micro switch in the door latch system. When the switch doesn't work properly, the oven doesn't know the door is closed. If the door isn't closed, the oven will not energize the magnetron. Capacitors and magnetrons are **** and expensive answers but these items are extremely tough. It is the tiny contacts in the micro switch that can not stand the repeated abuse given them when we (read me in that number too) open the oven while it is energized causing a repeated flash across the contacts.

Thanks for your question @ FixYa.com

If you gently push up on the door latch heads (hook-like devices sticking out of the door) there should be spring tension. If they just flop right up, the spring is off inside.

Normally the problem is not the spring, but a broken spring mounting tab on the door latch head (hook) assembly or the inner door panel.

If it's the door panel, it's usually easier and cheaper to use epoxy and some kind of hardware to fashion a new spring mount.

The door latch head (hook) is easy to replace or repair if that's the issue.

Normally you have to separate the door panels (as shown in the attached photo) and then you'll see the screws you need to remove.



Or you can watch a YouTube video (not a video I made) here that demonstrates how it's done.

You can order parts from Encompass here or the Sears Parts Direct Web site.

The door does come apart. Open the door and where the hinges are, there are openings where the hinges enter the door, this plastic piece (goes all the way around the door) With a small flat blade screws driver VERY carefully pry it (plastic) off, once off, check the latch end for the spring, typical failure for a Sharp is the little tab that the spring hooks to on the door, the only way to repair this so it will last is to replace the door frame. they are not too expensive, about $50 or so Part# FCOVB166KIT

I answered this personally via e-mail (and I do not mind peopke writing me personally). I think you may have a broken tab which holds the door latch head spring in place.
