Missouri Gentleman for Model Number Maytag MZD2766GE We have an occasional buzzing in our fridge. I figured out it's in the Control assy., temp. / Part Number: AP4070269 - and have replaced that. Didn't help. It used to buzz for about a minute, now it can go for 10+ (until we unplug the fridge and restart it). It only occurs when the compressor has been running and is then shutting off. I'm wondering about now replacing the Defrost Control Board - or getting a new refrigerator. Any ideas? Thanks for your help! This site is great!
Answer Hello Missouri Gentleman. You will need to check and see if the noise is coming from the defrost control board 61005988. If so, you will need to replace the board. If it is not the board, you will need to check the damper assembly WP61005971, and see if the noise is coming from there. If so, you will need to replace the damper housing assembly. Hope this helps.
