Maytag Wall Oven

[RAH52]

The issue with wall oven is that the cooling fan run constantly and never shuts off ,even with the control turned off .The fan worked to specs a couple of times and then failed . My question is this what turns the cooling fan on in the first place .According to the schematic there is no thermal disc ,how does the clock know when to turn the cooling fan on ,would it be from the resistance it see's at the oven sensor . Do I have a bad clock ? Has anyone seen this problem ?

Model MEW5530DDB

The cooling fan on this model is run by the clock. Whenever the Broil is selected or when the Bake temperature reaches 305 degrees F, the fan cuts in. The fan is supposed to run  after the oven has been turned off until it cools below this point. The sensor only plays a part in the cool-down portion of this, as the fan is turned on automatically when the display hits 305 in Bake. You can always test a room temperature sensor probe with yur OHM meter for a reading of around 1090-1100 OHm at 75 degrees F.

The clock would be the failed component if the sensor OHMS ok.

Thanks for the help repair-man . One question I have, how did you know the fan started at 305 F . No where in any service manual that I have read does it state that but you were exactly on the money ! Do you have access to a more detailed manual or are you you just smarter than the average tech LOL .anyways thanks a bunch .
