We have a Whirlpool fridge WBM46LW (around 5 years old) that keeps sounding the door alarm when door is opened, also the motor surges with the alarm and the light flashes. Suggestions appreciated thanks.

Hello All.
I would like to add my findings. 
My fridge WBM46LS of 11 years started behaving exactly as the OP described. I tried all the suggestions regarding holding buttons, power off etc to no avail.

I even found an online manual here
But that did not address the problem at all.

So I went back to someones suggestion about the Potency Module.
I pulled the fridge out and unscrewed the cover at the bottom left to get access to the Potency module.(Red plastic box)
Without even pulling it open I could smell the burnt electronics.
I opened up the case and found a scorch mark next to the big capacitor on the circuit board.
So far, so good.

Given that a new fridge of the same size/style is about $1300 I pursued the spare part.
I then tracked down a supplier in Melbourne with a new board/module for $148.50.  P# WPP326020913
Plugged in the new board in and fired up the fridge and its working just like new.
(I can give the address to those that want)

So I am happy now that a perfectly good fridge is up and working again.
