Question about GE Advantium 120 Convection/Microwave Oven

Sensor error and periodic beeping for Advantium 120

After making popcorn, screen sometimes (sometimes not) shows sensor error. It then proceeds to beep every 45 seconds. It does eventually stop, perhaps after glass carousel cools down. Never used as oven. Any ideas how to resolve?

    I do not open microwave during cooking of popcorn. Interesting comment on sensor error -- I'll need to focus on exactly when this message appears. I'll also need to check on internal fan running -- I'll put in some popcorn tonight -- but do not recall hearing any fan internal to microwave -- not ever.

    Listened to sound clip of fan. I can never recall hearing the Microwave does not make this sound.

    Model number is SCA1001FSS01. I've also confirmed the internal fan does not go one when making popcorn.

    I meant to ask for your model number.

    There is a bulletin about mistakenly swapped wires allowing interference to cause sensor errors.

    In other cases it is a software problem on the smart board.

    We have a sound clip of what a microwave should sound like when the cooling fan and high voltage section are operating here.

    Some notes from the owner's manual:

    If you open the door while sensor
    cooking, SENSOR ERROR will
    appear. Close the door, press
    START to begin again

    (Using a popcorn pad on a sensor model is one form of sensor cooking)

    Does this seem like it might be the case?

    Does it seem like the internal cooling fan is running properly whenever you're microwaving?

    When I say internal
    cooling fan, I do not mean the hood vent exhaust fan which you can turn
    on and off manually.

    I'm instead talking
    about the internal fan which comes on automatically whenever you

If the internal cooling fan does not come on when you're microwaving, the magnetron will overheat and the thermal cutout will be tripped, causing the oven to go dead until it cools back down.

If this happens more than a few times, the magnetron can be damaged.

If the turntable is not turning (assuming it's not set to be off) when you're microwaving, then the problem lies on the relay circuit board (sub PC).

If the turntable is wokring and the fan is not, then the fan motor or wiring is at fault.

At this point, with such odd problems, I recommend that you contact GE customer service for your nearest GE-authorized service center

Good luck.

My microwave stopped working one day. A few times before it completely stopped working, the magnetron would pulse and then shut off. Now the only time it does that is when nothing is in the microwave. If...

If this is an older oven, or an oven that has heated a lot of popcorn, or other low water content foods, then you might be looking at a magnetron that has become intermittent. The symptoms you describe, however, do not match the symptoms you usually see with this type of failure.

Based on your description of the problem, I'd investigate the possibility of an intermittent power relay. The contacts on these eventually burn and sometimes don't make a good connection. After the contacts first close, there're is an initial surge of current that might make the relay functional for a second or two, and then the damaged contacts no longer make contact.

Burn popcorn???

I have never found a microwave oven that worked perfectly for popcorn. If you are using the "popcorn" button it can only guess at what your popcorn needs. This is my soultion at work as well as at home or a fiends place. I watch the process and listen to the pooping. When it get down to two seconds between pops I shut it off. Each type of popcorn will act differently but if you keep using it and keep using the same microwave, eventually through a process of testing you can come to a time that will work with your process. One other thing the popcorn has to be on a rotating table and has to be put in with the correct side up. You will never get it perfect but you want to cut it off before it begins to burn.

The beverage sensor on my advantium after six months is not working - coffee boils over before the over goes off. Sometimes it will say sensor error.

You can find helpful exploded views and order parts (including the humidity sensor) here.

The Advantium service manuals are here and here and have disassembly info and part numbers.

You can download GE owner's manuals and installation instructions here.
