This is usually caused by either a bad door switch or a loose door switch mount, which are pretty simple problems to fix.

Even though a door switch clicks, it may still be bad inside.

Door switch or mount trouble can be caused by slamming the door or by opening the door while it's cooking without hitting the Stop pad first.

There are plastic mounts inside the microwave which hold the door switches and onto which the door latches lock when you close the door.

The screws on these mounts may be loose. If they get too loose, the switches will not be activated properly.

Sometimes it's a broken tab on the switch holder, allowing the switch to rotate just out of position. This tab can be hard to see, since it is under the bottom edge of the switch.

If you or someone you know decide to look into it, we have critical information on safety, disassembly and door switches at our site, and our link is at our listing here on FixYa:.

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

There may also be a "mini-manual" hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting & testing.

If you only need a switch, you can order a universal type here for $5 postpaid.

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

Sunbeam microwave not heat


Place a glass pie plate in the oven with about 1/8" deep water in it. Turn the oven on high for about 30 seconds. If you get one small spot with intense boiling, the stirring antenna at the top of the oven is not rotating. It's usually driven by a small 60 RPM synchronous motor. To get at it, look for a pull-out plastic locking pin that holds the plastic dome or plate to the tope of the oven cavity. You may need to rotate the cover counter-clockwise a fraction of a turn to unlatch it. Sometimes greasy food vapor gets in there and gums up the bearings. Clean very thoroughly, but be careful not to bend the antenna blades. When you reassemble, make sure the antenna is properly seated in its bushing and engaged on its drive shaft. Repeat the test to see if you have even heating.

If you see no evidence of heating anywhere in the oven, check to see if the door switch in series with the transformer is malfunctioning. If the door switch is OK, you'll need a high-voltage measurement probe to determine whether the magnetron has failed, or (more likely) the high-voltage capacitor or diode is bad.

My oster OGB8901 microwave is having power situations it sometimes the power works and sometimes not i can hit the top and the power will come on than in the middle of cooking something it (the power)...


Hi, Could be a timer issue. Don't hit it anymore you will do more damage to it or even get a shock. Take it to a repairman or someone that has worked on one. Good luck.

The oven doesn't work, the timer works and the light comes on


This is a strong indicator the magnetron has failed "heats food" and is the heart of the system. If microwave oven is a few years old better to invest in new.

Food won't heat up


Hello, I had the same problem, and just fixed mine. Start by turning on your microwave (on mine, the light turned on and timer worked, but the fan nor the plate turned)... push the door upward and see if the microwave turns on... (mine did). so far so good. open the door and take the upper hinge cap off with flat head screwdrive. take the door off and place a small washer on the bottom hinge, put the door back on. your microwave should be good now. essentially, the door just needs to be pushed up a bit so it will work.
good luck, hope that works for you...
