Oster microwave model ogf41101 all works but dont

YOU GOT IT - LANDFILL!

Actually, had built in over the stove microwave, that "JUST STOPPED" working one day.

I looked around. You can get a good new Microwave for a very low cost these days (yes, it won't last forever, and will be more landfill - but that's how they make things these days)

Try dealnews.com - it constantly updates, and I got an awesome deal on a new microwave (with free shipping) must be 5 or so years ago ... it's still working great .... and I use it a lot.

From user abu_abdillah351 has mentiond this before

the problem is the high voltage fuse, incapsulated between the transfo and the magnetron. This supports up to 5000V and usually rated something like 0.65A/0.7A/0.8A and even 1A.
When you open the capsule, you'll see it sitting there between its two connectors

If there is no heating please do not switch on unless you have confirmed the fault. It is possible that the Magnetron is faulty, the temperature cut off is faulty or the main capacitor is short. It is also quite possible that insect can get into the oven and create soft spots. When you switch on these will create a short and make the voltage jump and in the long run damage the magnetron.
So Remove cover after disconnecting , check for dirt/moisture in the cabin, if so wipe clean and dry, check the magnetron and area clean and use an jet air to clean off.
Make sure that the program controller is working if not check power - step down supply, the pads are responding- if not faulty pads- or the door switches, if contact is not through the microwave will not work.

Now keeping clear of the microwave, switch on, use a cup of water inside to test.
If you notice any sparks shut off as the magnetron or the main HT capacitor can be faulty. replace with same type.
If there is heating without any issues, you can use the microwave safely

check the high voltage fuse on the inside of the unit if this is not showing a fault then you would most likely be looking at replacing the magnetron in your unit this is the most common piece beside the fuse that shorts out and is what is directly realted to what is actually heating your food depending on what type of microwave it is it may be cheaper to just buy another microwave if the place of origin on the microwave came from a walmart or target store where as buying a magnetron may cost you between 50-100 dollars which is about the price of a micro wave at one of these stores if you have any further questions message me back and please remember to rank how this opinion has helped it allows me to continue helping others in similar situations Thanks Rick

Blown High voltage fuse. 5000 volt .83 amp
Im going to replace mine and see what happens

If everything works, but the microwave oven does not heat, this is commonly caused by a failed magnetron. The magnetron is essentially, the heart of the oven that produces the RF energy that is used to heat your food. In order to replace a defective magnetron, you will need to consider the following:

1. You will need to uninstall the oven from over the range in order to replace the part (you will need to do this anyway, if you decide to buy a replacement oven).
2. Ensure the oven is UNPLUGGED before servicing anything inside the cabinet and remove the exterior case in order to access the magnetron. There are several websites that you can use that illustrate how the oven is assembled:
searspartsdirect.com pcappliancerepair.com appliancepartspros.com
NOTE: If you've never repaired an appliance on your own before, a microwave oven is usually not a recommended appliance to start with. Some models can be rather involved in taking apart.
3. The magnetron replacement part number for the model you have listed is 505137 and is listed as item 1-12 in the parts index. It costs about $100. 4. This model also has a thermperature fuse, listed as item 1-10 that can also cause the same symptoms if blown. The fuse is essentially a thermostat acts as a fuse if the oven cavity overheats. The part number is 46-1518457-3. You will need to remove the thermostat from the oven and take a resistance check across the component terminals to determine if it is good or not. A low resistance reading indicates a good thermostat. An infinite reading, indicates a blown thermostat and needs to be replaced. The average replacement cost is about $10. I would recommend you check all fuse associated with the oven before assuming the magnetron has failed.
Review the parts illustrations at the recommended websites to see if this is something that you may be able easily take apart and reassemble.
If you have any questions, please post back and let me know. I hope you find this information helpful.


CAUTION: DO NOT operate a microwave oven with the exterior cover off. The voltage inside the High Voltage network where the magnetron is installed can exceed 3,000 volts!

The fuse you are referring to is usually the line fuse. If it were blown, the microwave oven would be completely dead. Since you HAVE power and the turn table, fan and lights all work, the line is not the problem.

If everything works, but the microwave oven does not heat, this is most commonly caused by a failed magnetron or internal thrmostat. The magnetron is essentially, the heart of the oven that produces the RF energy that is used to heat your food. In order to replace a defective magnetron, you will need to consider the following:

1. You will need to uninstall the oven from over the range in order to replace the part (you will need to do this anyway, if you decide to buy a replacement oven).

If the model number you posted this question under is correct, the magnetron replacement part number is 10794402. NOTE: This model also has an internal thermal fuse mounted on the magnetron that, if tripped, could give you the same symptoms. The thermal fuse acts as a fuse if the oven cavity or magnetron overheats. The part number is 59001951. You will need to remove the thermal fuse from the oven and take a resistance check across the component terminals to determine if it is good or not. A low resistance reading indicates a good thermostat. An infinite reading, indicates a blown thermostat and needs to be replaced.

I would recommend you check the thermal fuse, first as the replacement cost is much less than the magnetron.

There are two fuses in a microwave oven, and for the non-heating problem the problem is the high voltage fuse, incapsulated between the transfo and the magnetron. This supports up to 5000V and usually rated something like 0.65A/0.7A/0.8A and even 1A.
When you open the capsule, you'll see it sitting there between its two connectors, and you'll notice the filament inside the glace is broken. Buy a new one and your machine will work like a horse.
NOTE: Try to get the same ratings fuse, or else the oven will smoke and smoke the house with it, so be careful.
The other fuse is smaller, and usually ceramic one, which can be found on the PCB, if that goes, you should get no power at all to the machine. If not sure, let a professional do the job, it's safer.
