My Panasonic nn-s262 fan and light not working. All other functions are operational. Is there a fuse in the microwave that needs replacement?

could b the fan or turntable motor

There's a fuse inside near the power transformer . It could have blown. Now you need to find the reason why it did.

follow this steps and fix it. God bless you
No power to outlet (overload or fault in microwave or other appliance).
2. Blown main fuse - likely due to other problems.
3. Open thermal protector or thermal fuse.
4. Defective controller or its power supply.
5. Clock needs to be set before other functions will operate (some models

This indicates the magnetron has a shorted winding in the filament.

No! the main fuse is okay because you would not have any power. I would check all door switches because they control light, fan, and turntable. If you are handy with a meter, set to ohms, disconnect one wire on side of switch, use meter to test, readings should show open/short when pressing the button and releasing it, replace wire to switch and repeat, if you hit one with the same readings pressed in or out, change the switch.

my microwave shuts off after a few seconds. is there a fuse that needs replacing?

internal short that can damage your control panel but do not try to fix it yourself its got 4000v !!! sorry :( your life worth more then this microwave.

hi, check that the cooling fan is operating and to sufficient speed to cool the magnetron or the thermal cutout mounted to the magnetron will cut power

2 fuses in a panasonic does not sound enough.
have you checked the main incoming power protection fuse normally 10amp or higher.
most panasonics have approx 4 fuses so keep on looking
