Question about Sharp R-1490 Microwave Oven

Strange rattle when microwaving

When we use our microwave, GE Spacemaker XL1800, there is a strange rattling sound while the blower is on. When we use the vent fan, however, the sound is not present. The microwave is otherwise working properly. We have tried to look inside in order to determine if anything is loose, but nothing seems to be. Can anyone help? Thank you.

Chances are the blade assembly has come loose on the shaft of the internal cooling fan.

This can be solved with a couple of drops of super glue at the spot where the blade and shaft meet, then allow it to dry for several minutes.

You can find helpful exploded view diagrams and order parts by entering your full model number here.

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

Then you'll see the cooling fan.

Please let us know what you find.

We're happy to help you with free advice and we'd appreciate your thoughtful rating of our answer.

GE Spacemaker XL1800 vent fan doesn't pull air from beneath


On the exhaust system (top of unit) there is a small metal 'damper' that is most likely stuck shut. If that is all clear then you have a problem in the duct work of the home.

Unplug for about 5 minutes and allow to reset. If the problem persist, you might want to try replacing the control panel (the one that have all the numbers and timers). Good Luck!

I have a ge above range spacemaker xl1800 it seems to work fine except their is a rattling noise when its running it sounds like a bad fan or something comeing loose it seems like its comeing from under...


The noise you are hearing is due to the fan. The fan is used to cool the magnetron during cooking, and because this fan is not working the magnetron is overheating and the thermal protector is opening, killing power to the unit. All you need to fix this is a new fan blade. The fan blade(look for part #80) is slipping on the motor shaft ( the noise you are hearing).

GE XL 1800

If the blade is broken then you can buy a new one from---

GE FAN BLADE

Please ask for further clarifications.

A Fixya rating would be appreciated if you find it useful.

Outside venting GE Profile Spacemaker XL1800


Your vent flap could be taped or it could be faulty installation not allowing the vent to open. If you take the front vent cover off, you should be able to reach in above the fan unit and gently push the vent flap up, it should move freely with no binding. If it doesn't it is taped or blocked. If it is taped, gently putting upward pressure on the flap might release the tape. If that doesn't work the vent installation is blocking the flap. You might have to remove the unit from the wall (two people to do this) or disassemble the vent duct above the microwave and rework the interface for clearance.

hope this helps,

A simple test is to place a piece of bread in the microwave ( it heats up very fast) and then if your microwave was actually ON and generating RF, the bread would get hot very fast.. If it remains cool then only the fan is on. It appears that you may have a faulty door switch thou because once you open the door, your microwave should be off..

Are you sure the VENT is not on? That blower will operate regardless of the door open or closed so you must switch it OFF.

XL1800 still works fine but makes a lot of noise while on.


It may be the stirrer in the ceiling area.
