Question about Microwave Ovens

Whirlpool Duo Microwave Model # MT3090XAQ-0

This microwave just stopped working, I'm thinking b/c the light is burned out/needs replaced? Didn't trip a breaker, outlet is okay. If this is the case, how in the world do I replace this bulb? Inside on the right side, there are two narrow rectangles with hex screws, but it seems it would only remove two covers the size of said rectangles.
Help!

Manufacturers used to include access panels in the rear or side so you could easily change the bulb. That exposed the customer to 110V connectors, and that posed a real liability threat, so they stopped using them.

You now must generally remove the outer cover to replace the bulb, and that's the case with this model.

If you or someone you know wants to look into this, we have *critical* safety, disassembly, and troubleshooting info at our site, and our link is at our listing here on FixYa: http://tinyurl.com/yzjozk

You can find helpful exploded view diagrams and order parts by entering your full model number here: http://tinyurl.com/gv383

There should also be a "mini-manual" hidden inside the unit behind the control panel, which is very helpful when troubleshooting.

Please feel free to contact me directly if you need more help.

New microwave stopped working after 15 seconds


Possibly the fuse / breaker is tripped, usually all outlets in one room share same breaker. Check breakers (or fuses) or try outlet in differnt room. If the outlet has power, (plugin a lamp to check) and the microwave still does not work, take it back to store for replacement or refund.

My light bulb has stopped working and will not work after I have replaced it with a new one


It could be either a separate door switch for the light that's gotten crufty (sometimes just cleaning them makes them serviceable) of the microwave that needs to be reset. Just check for tripped circuit breakers, since you've already unplugged the thing to swap the bulb (I expect.) Then check your bulb's continuity, then check the socket and switch functions if things aren't sorted.

Whirlpool(GH7145XF2-0) does not work occasionally


That's how it would sound if you were cooking on a power level less than full power.

If you enter the cooking time and hit Start, it should cook at full power by default and not cycle like you describe.

If you are using some sensor cook setting or automatic type cooking setting, it may cycle like that normally.

The first thing to try is a "hard reset". Unplug it from the power line for a minute, plug it back in, set the clock, then try again.

Let us know if the hard reset doesn't fix it.

If you don't have your manual, you can download it free here. Check the lower right area to enter your model. number.

The magnetron has failed and has damaged the waveguide. This type of failure is generally unrepairable. First look in your owners manual for specific warranties, then contact Whirlpool and explain to them what has happened.

If you need further assistance, let me know
