Thank you for using Just Answer.
We need a bit of clarification in order to answer this question best.
We will need you to re-check and post that model number. It doesn't come up. You should find it on the inside wall on a sticker (if it's only 15-20yrs old) or on a metal plate (if it's older).
If you don't see the model number there, try behind the machine.
Please also post the serial number which should be next to the model number.
Thank you for you patience.
This model (from a quick deduction) would be approximately 15 years old. I got this from the owner's manual and looking at the unit. I would not be more than a year or two off and that would make it slightly less old.
If you want something more accurate than that, you will need the serial number and you can contact GE directly with it. They will be able to hunt down the production date for you.
Here is the owner's manual. If you don't have it, it is something that could be useful.
If the unit did not start it is possible that it's in defrost cycle. If it doesn't start in an hour then there's a problem with the either the compressor or the relay/starter.
