not seller's fault, it's the defroster controller manufacturer that makes a part that doesn't last
defroster fail, usually find refrigerator not so cool while freezer still ok
with 1/4" nutwrench, pull panels in back of freezer and defrost with heatgun if clogged with ice
this will restore function until it ices up again, depending on how humid it is
resistance measurement of the defroster heater element should show continuity- this has not failed for me - the control fails anywhere from a year to over a half dozen years, replaced 3 times in 15 years
this defroster controller module is located in the upper right corner, inside the refrigerator (not freezer)
there is a good youtube on removing the plastic panels and getting to it
2 screws hold it in place, one connector installed the same way the old one was
watch the video, this is not hard and does not take long, and this part is not expensive
unfortunately the reliability is quite poor, to the point where some places sell them in pairs
so next time, and there will be a next time, you can get the refrigerator back to normal quickly
the reviews on the Maytag MZD2766GE indicate others also found it unreliable
Fixed my refrigerator - My 20 year old Fridge works like new again!
The Refrigerator Defrost Board Adaptive for Whirlpool 61005988 was received timely. I installed it easily, and the fridge works like new again. Couldn't ask for more.
