. I ordered a main board and promised the customer that the new board will fix the problem.
test # 3a in the manual should help http://appliantology...raining-manual/
I believe the rps in this manual is called the "optical sensor"
2nd point....never ever box yourself in with a customer by saying a board will definetly fix a problem, if you are not certain yourself. Leave yourself some wiggle room...ie "the board communicates with xyz...sometimes it's difficult to determine where the fault is but usually it is the .____ (board in your case, since you already ordered it). I will order the most common part that fixes the problem. If the problem continues, I will get the second most common part and return the other. Through testing, you may well determine the part may be the rps instead of the board. Then you saved the day...that is if the part is cheaper than the board.
Appliantology is, however appliances are not, an exact science for I know there are a few refrigerators that actually hate me.
