MY MICROWAVE WILL NOT DO ANYTHING

Question

My microwave has the code A-1 in the display and sometimes when it feels like it, it'll beep and go to A-2 and A-3 and back again. I can't do anything with it. The keypad won't accept anything and I've plugged and unplugged and even tried differnt outlets and still the same problem.Is it time for a new microwave?hotpoint RVM1625 microwave has a F3 code and it will not let me do anything.
