Maytag CGR3730ADH (30" range) lock light blinking after power outage

[spup345]

I have a Magic Chef (aka Maytag) CGR3730ADH 30" range. We had a power outage 2 nights ago. Today, for the first time since the outage, we tried to use the Bake mode on the oven. Pressed Bake and instead of defaulting to 350 degrees, instead it just made the "lock" light blink on/off. It worked perfectly before the power outage. I find it hard to believe that the lock light blinking is related to the oven door lock simply because everything worked perfectly up until the power outage. Would a surge cause a control board issue like this, or is it truly coincidental and maybe something else is wrong?

3 questions:

1. Must I replace the entire control board for the unit as a result, Part# W10162787

2. Is it easy to simply remove the old board & plug in the new one? I'm a good DIY'er & have wired outlets & recessed lighting myself, so if it's fairly straightforward.....

3. In the future, should I plug all my major appliances into a small surge protector instead of directly into the wall outlet, would that prevent the circuitry from blowing?

Thanks!!!!

And, FYI, the self-clean mode does work, so it's probably not a door latch thing...I just tried it....

Sorry....my bad...I push self-clean, it then says "Dr" in the display. I then move the lock over on the door and then it goes to a timer of "3:00" so apparently, the door lock is working. However, I wait about 30 seconds and then it pops up "F9" and turns off. So it seems like the control board just isn't able to ignite the oven whether in bake, broil, or self-clean mode. Again, I'm thinking the control board is bad...

The door latch is your most likely problem and least expensive.
Replace it.

Problem solved. In summary, it was the control board that blew due to the power outage the other night.

I bought a new control board, part # W10162787

I unplugged the range. Then I unscrewed the 4 screws on the back upper panel on the stove to access the control board. Unscrewed the 4 screws holding the control board, popped off the 5 wire connections from the board, put them on in the same spots on the new board, screwed it back in, plugged the range back in, tested it, and everything worked! Voila.

Hope this helps folks in the future, very easy to do yourself if you have a screwdriver.

(Only tricky part is popping off the old connections, you need to push a sharp object into the hole on each connector to be able to slide the connector up & off).

I had the same problem as a result of a brownout screwing up the control board.  I ordered a new control board from repair clinic (I needed white) as described above and problem solved! Thank you Appliance Junk and Repair Clinic.  The link below is the white control board I ordered.

You might want to get a surge suppressor to keep the new board from being ruined in the future. What do you think?
