Hello, We just bought a house that had a brand new microwave installed in it. It is flashing numbers 1,2 and 3 over a period of time and won't work. At some point it will work when I hit the start button, which is completely random. The key pad won't work up until that random time. Thank you in advance for your assistance.
Some newer microwave models will not function UNTIL you set the CLOCK Function ... ok
There should be instructions in your microwave MANUAL to tell you how to do this; as it can vary widely between different brands and models.

Is it possible someone may have sprayed cleaner directly onto the keypad area?
This causes moisture to get into the keypad and sometimes onto the control board.
This could mean that they control panel frame with keypad (membrane switch) would need to be replaced.
Can you give more details on the cleaning?

You have a failed
membrane keypad.
If you (or someone you
know) might want to replace it yourself, I have uploaded a handy guide with pictures showing you what's typically
involved.
You can usually find
helpful exploded view diagrams and order parts by entering your full
model number here.
There
should also be a "mini-manual" hidden inside the unit behind the
control panel or hidden on the left side behind the grille, which is
very
helpful
when troubleshooting & testing.
If you would like to
have us do this repair for you, we do that for $39.95 plus part costs.
At
our Web site, we have a video
available showing how to remove a typical
over the range control panel assembly in under 5 minutes.
Feel free to contact me directly (and please remind me of your
model number) for more information & help.
We're
happy to help you with free advice and we'd appreciate your thoughtful
rating of our answer.
