I have a Maytag Bravos MCT MEDB850WQ that does not start. I run the on board diagnostics and no fault codes come up. I checked the thermal fuse and exhaust thermistor and they both are within spec. I check the door switch and motor belt switch and they seem to be working. I checked the resistance of the motor windings (starting and main) and they are within spec. I even replaced the control board with a new one and the problem still exists. When I begin to run the interactive diagnostic tests while the machine is still in diagnostic mode and press the "Wrinkle Prevent button" the timer displays the characters "CO". What does that mean? Does this confirm that the user interface assembly is bad? Thanks
