Question about Sharp R-1500 Microwave Oven

1 Answer

Doesn't heat anything anymore...

Hi! I read your post and saw some advice that seem related but wanted to verify with you before I do anything.  I did not hear a pop but that doesn't mean it didn't happen.  Our family usually never leave the kitchen when anything is being cooked unless someone is there for safety reasons. The night before the microwave worked fine. The next day I tried to heat a cup of water and nothing was heated.  Fan, control unit, interior & exterior light, keypad all worked.  So I suspect the magnetron isn't working.  However could it be just a component on a board that may have gone out instead of the magnetron?  I know my way around electronics and upgraded the keypad and display when that went out a few years ago.  I'm not sure what electronics are involved when replacing the magnetron but when a board level component goes out is this something that can be troubleshoot and repaired or do you just replace at board level and not deal with components?

Smh9187w vent fan popping noise

There are no bulletins covering a recurring issue with the exhaust fan on this model, so I would suspect the failing motor, an obstruction in the blades, a loose blade assembly, or a damaged wire arcing to the frame.

It will take some visual inspection with the oven removed from the wall (see your installation instructions) and the cover removed.

The service manuals for the variants are here:

You can order Samsung parts from the Pros here or from Encompass here.

Electrical short /pop sound & now it doesn't heat. Everything else works. Any idea what went out.

The signs are not always evident, but from the description the magnetron has failed.

The door won't pop open, you hear the click and you have to manually ply the door open

Since no model number was posted, I have to give a general answer.

It's likely that one of the door opening parts (most likely the door open button or lever) is broken.

You can find links to helpful exploded view diagrams and part ordering help here.

I recommend that you bookmark that link to your favorites.

Everything works, sounds normal, but it will not heat anything.

Owners of a GE WES model might want to look at this blog post.

Hopefully its still under warranty.

If so, GE Customer Service is here.

If not, I'd replace the oven.

GE Spacemaker microwave, runs only 2 seconds, then stops

The problem you describe on your JVM1650SH02 is a failing "noisy" magnetron which is emitting electrical interference that disrupts your microprocessor.

At my Web site, I have a video available showing how to remove a typical over the range grille and control panel assembly in under 5 minutes.

You will find a technical sheet hidden behind the grille or behind the controls. It's handy for locating parts and troubleshooting.

You can find an exploded view and parts list by entering your full model number from the tag here, and you can also order parts there.

On your model, you may need to remove the oven from the wall. The installation instructions here will be helpful.

Pro tip: In many GE models, dropping the floor plate that holds the high voltage transformer is necessary to get the magnetron in and out.

For more free DIY and other help & advice, feel free to contact me via my site.

Please include FULL model number*, FCC ID number*, + detailed symptom information. ( * on the tag in cooking cavity or around door frame or control frame or on back)

Microwave Stops after 4 seconds

If the digital programmer circuit / controller does not get a feedback signal from the inverter for a period of 3 seconds, the controller will stop the cook cycle.

The clicking is common with inverter-related failure.

Due to the lethal voltages used and produced, I do not recommend that an inexperienced person work on these.
