MEW6630BAS Maytag Wall Oven - Overview

Parts arrived in three days and it was an easy swap of the hinges but the same problem still existed: the oven door wouldn't close completely, so the oven light stayed on and the convection wouldn't work either unless the door closed all the way. The replacement hinge's springs apparently aren't strong enough to close it and the springs aren't adjustable - which is a design flaw. I did correct the problem though, by using three dollars worth of 1" round magnets, which I placed inside the door: they stay put and are strong enough to pull the door tight.

This is a Jenn-Air double oven. Turned off circuit breaker to the oven. Removed 7 screws that hold the top panel in place. Removed 3 cable/connectors from the clock module so panel can be removed from oven and placed on a table. Unscrew 4 hex head screws attaching clock module to front panel. Press on two tabs and remove circuit board from plastic frame. Replace with new board reversing dis-assembly sequence.

After examining the old board I discovered that the 470 microfarad aluminum electrolytic capacitor (in the corner) was badly deformed. I replaced this. Now I have a spare board. I believe that the failure (common in Jenn-Air ovens) starts with a transient on the power line (it did with mine). This damages the capacitor which progressively gets worse. This capacitor probably acts as a low pass filter on the power supply for the display. If any of you are into electronics, I would suggest wiring a zener diode across the capacitor to suppress transients. I wish the Jenn-Air engineers had put this in the design. It would have avoided a lot of costly repairs and saved them the bad reputation that they have as a result of this board failing over and over again.

I ordered the door glass from Part Select, which arrived quickly and in good condition. I loosened two sets of screws under the bottom glass holder frame, removed three screws at the top of the door to give more room. Slid the glass in place, re-installed and tightened the screws.The stove door looks great and works great. Great customer service too.
