Fans and lights don't work on our Advantium sca2000bbb. Display does. The main fuse is OK. Is there another?

Yeah pal, you've not gone deep enough yet. You'll find a power wire bare inside the unit, pull it apart and tape that wire up to stop it from grounding out and blowing the fuse.

Our unit was doing the same thing,
took it into the repair shop, they said there was nothing wrong with the unit, replace the main breaker that supplies power to microwave and try again.
Sure enough the breaker became defective, and we never had issues with it before, but now the unit has not had a single problem.

Dead appliance, power on wall outlet.

YOUR SAFETY IS PARAMOUNT!

Attempt this only if you are competent.

If your appliance has absolutely no functions at all, remove it from the mains supply, remove the case and see where the mains lead goes in to the appliance and follow the cable until you find the main fuse.
ONLY USE THE SAME TYPE AND RATING OF FUSE TO REPLACE IT.
The usual cause of this fuse failure is the door switches are contaminated or sticking. Check the door switches before putting power back on to the appliance.
Hope this helps.

Microwave Oven Basic Troubleshooting Tips

check power. if good then check for fuses inside unit

If the microwave side is not cooking, it may be the magnetron has died, if so, it may be expensive to repair and you may have to consider another purchase.

if anything like my own it is the led blub thats blowen - major hasel to change out - get some one who knows these cookers/ovens...

If you want it fixed call sears for service. I would not recommend taking this microwave apart if you dont work on them for a living. only because there are 14 million thing that need to be remove to do a simple repair.

Remove the housing, it covers the sides and top. Then look above the display near where the 220 cord enters. That is the main fuse. There are 4 others in this oven. Good luck.
