15 year old sharp carousel built in microwave, model #R5A53, has quit heating. Everything else is working fine.


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!

Sharp R-150 microwave made a buzz sound and shut off, no power to microwave


Hi,
When the microwave won't heat, but you hear a loud buzz, you usually have a defective power diode, high-voltage capacitor, or magnetron. Also usually, when your microwave oven doesn't work it all, the internal fuse (thermal fuse) is blown. This fuse protects both you and the oven.

Not geting hot


HI. in most cases, this will lead to a failed Heating device(magnetron tube).It would be wise to check the Magnetron cutoff fuse to be sure of its integrity. if the fuse is blown, simply replace it. if the fuse continues to show continuity, replace the magnetron.

(((The fuse is located inside the unit along side the magnetron)))

Microwave not working-Sharp 798 M,oven Grill ok


Sounds like the magnetron has failed. This is the component that produces the microwaves that heats the food.

The cost of the magnetron is about 95% of the cost of a microwave oven. Most people don't, for this reason, replace the magnetron, they replace the whole oven which is probably what you will end up doing.

There is a possibility that the circuit that provides power to the magnetron is faulty and you need to take it apart, find the proper electrical leads and test them with a volt meter. To do this you have to remove it from its mounting and take it apart. It is a fairly lengthy process however.

3 year old unit, oven works, microwave does not


hi,

You may need a new magnetron, contact sharp or the store you got it from; most microwaves have a 3-5 year warranty on the magnetron. If it's not in warranty, find a good appliance repairman, this is a difficult and dangerous repair job.
