Microwave turns on by itself for one minute then it prompts F3.

Assuming there's no moisture, grease, or other foreign matter on the control circuit board (especially in the area where the keypad connects) then "F3" means you have a shorting membrane keypad. This part is no longer available from the manufacturer, but in case you can find one in "new old stock" from a local or online distributor, the part number was 5304430278. If you find the part, feel free to contact me here or at microwavecontrol.com for detailed replacement instructions. Good luck.

I unplugged my aunt's microwave to clean it, when I plugged it back on the light inside is on and the plate turns and the fan goes, cannot do anything with it, can't cancel or start, only way

Likely when you cleaned it, grease mixed with the cleaner you used got between the button panel and the actual button switch behind the panel, making it stick on. Will need the model to determine how to remove the panel to clean underneath...OR, it may dry out and start working normally again.

When the door is closed it continues to run

Try to press "Reset" a few times. Sometimes they forget to clear after timing out. Hope this helps.

Turning it on for 90 seconds

Hey friend, thank you for your inquiry!

I understand that you would like to set your Frigidaire microwave for 90 seconds. Based off the Use and Care Guide you would press "Cook Time" and then enter "90". That would start your microwave for 90 seconds. If that is not your question please provide me with additional information for your current issue. I hope this information is helpful. -Matt

Stopped working after I changed the handle.IT automatically turns on when closing the door.but doenot heat. have to keep the door open to keep it off.

This sounds like either a bad door switch or possibly a latch head problem from taking the door apart......

Was working then everything went dead

If after a reset, at the household circuit breaker box, does not prove to be successful, sounds like you will need a new control board and a full diagnosis to make sure the board did not short anything else out internally. This is not a typical DIY job, so I would recommend a technician complete this for you.
