Is it possible to check the magnetron

F7 Error Code On Microwave Ovens With Inverter Board

An F7 error code could be an inverter board failure. Anything else that prevents microwave energy may also cause an F7 error, and must be checked. The technician should perform the following procedure to test for an F7 error code:

1. Check the magnetron.
2. Check the magnetron TCO (it should be closed).
3. Check the 3 interlock switches.
4. Check the harness wiring.
5. Check the electronic controls.
6. Check the inverter board.

For more free help, feel free to contact me via my site with your detailed symptoms and full model number and FCC ID number as shown on the tag in or on the oven.

Its must have the manuql and alsoon its body there must be one notice on it or open it and check inside the transformer also there is asmall paper

NOTE: Microwaves have a capacitor in them which can give you a massive shock!!! Be careful what you touch.

You need to remove the outer metal cabinet, you will then see a large square box with fins on it, this is the magnetron.
About the only thing you can check is the inline fuse inside the microwave, it will be in one of the wires that runs to the capacitor and you can check this with a multimeter . If the fuse is ok then the fault will be with either the capacitor or the magnetron, neither of which can easily be tested without specialist equipment.

Check all the sensors, this is possibly your problem.

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)))

The most common problems of microwave oven are the HV capacitor, HV diode and lastly the magnetron which is the main part of M O. check the capacitor and diode first, if its okay, then you have a decision to make. replace the magnetron or the whole unit. magnetron are costly

Sounds like the magnetron has failed. This is the component that produces the microwave that heats the food. The cost of the magnetron is about 95% of the cost of a microwave . 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.
