Dropped a hammer on the range while removing a ceiling light. Viewed a How-To video on Google. Ordered the needed parts. Followed the steps from the How-To video. Reinstall was a bit tricky by myself - could have used an extra set of hands. I have a few words of caution: 1) Put something between the range top and range - like a sheet or drop cloth - to prevent a dropped screw from falling into a crevice in the stove. I dropped a screw and was unable to retrieve it, even with a magnet. 2) Makes sure you remove all bumpers, screws, clips, etc. from the item being replaced and put them on the new item if the new item does not come with replacement bumpers, screws, etc.
Unplugged oven electric and turned gas off. Removed all back covers from the unit. Removed the cover on the inside covering the burner and fan in the back of the convection oven. Removed the nut securing the fan to motor shaft with helper holding the motor. Removed the three electrical wires attached to motor, making note where they go. Removed screws mounting the motor to oven. Removed motor cooling fan and shaft spacer from old motor. Fit in same orientation on new motor. Replace all parts in reverse order, restore gas and electric, turn on and test.
