KBMC140HBL0 KitchenAid Microwave Oven Combo - Instructions

Open the door and removed the 2 screws that hold the front
glass and stainless steel panel (Hold on to the door handle
or the face and glass will come crashing to the floor; learned this after the first time a couple of years ago $$$). Set the stainless steel panel in a safe area until ready for reassembly.
Next, you must remove the black plastic cover which is still
remaining on the door in order to get to the springs. There are 2 screws that hold the plastic cover which are difficult
to access without removing the side and bottom trim of the
microwave opening. The spring was easy to replace at this point and didn't require any tools; just observe when taking
the broken one off, plus you can use the other spring as a
go by. Replace the black plastic cover, the bottom trim, the
side trims and the stainless door panel and it's complete!

Just had to remove the screws holding the outer part of the door on (didn't have to take off the entire door). Using the other door spring (most models have two that cross) as an example, the new spring was fairly easy to place. Only problem is that the new spring was made from a smaller gauge metal and is not nearly as strong as the original, making the door feel heavier when opening/closing than before. The difference with and without the 2nd spring is barely noticeable. Had I known that they were making the parts cheaper now, I would'nt have bothered fixing it at all.

This is the third time that the bulb went out.It took two Sears service technitions to remove the entire appliance out of the cabinet. The entire top has to be removed and the insolation has to be pulled back to get to the electrical wire. I am waiting for an appointment to get Sears to do it again. The door springs have broken and you have to make sure the door is closed before walking away. It has a heavy glass and the weight is pretty heavy. Robert.

Removed all terminals and block mounting screws. Repaired one burnt terminal and reassembled. Replacement part was an exact fit and reassembly whnet very well.

cut power off and placed sturdy table same height as bottom of oven in front of oven. removed trim screws. pulled oven out onto table. removed top cover and panel on left side . tested transformer to be sure it was bad. then replaced transforner

Ordered a new one, put it in place in less than one minute.

The replacement of the blower was an easy repair. Just had to remove two back panels of the oven and the blower was then very accessable. Just remove the two electrical wires and then three screws and the blower came right off. Put the new blower on with the three screws and replaced the 10 or 12 screws holding the back panels and the job was complete!. The difficult part of the job was removing the combo unit from the cabinet to access the back panels. That part took some effort. Had to build a platform to slide the oven out onto after I disconnected the electrical feed wire (#6 wire) located in a junction box in my attic. Once that was done, the actual blower replacement was simple. The turntable motor was a different story...Although replacing the turntable motor was going to be as easy as replacing the blower motor, I couldn't access the underside of the microwave without disassembling the whole combo unit cabinet! That was very disappointing to me that Whirlpool didn't make that part easier to access, so I didn't replace the turntable motor. Too bad but we are just going to live with the turntable not turning!!

The replacement turntable we received was an exact duplicate of the original. It was as easy as rinsing the new turntable, taking the old turntable out and putting the new one in.

Part arrived in timely manner and placed it in microwave oven.

Set the new one inside the microwave

Just put it in

Fool proof.

Ordered a new motor. Removed the outside trim of the oven-microwave combo. 2 screws at the bottom of the trim. Removed the screws that held the combination micro and oven unit in place. Removed the top and bottom black plastic grill of the microwave. 3 screws each. Pulled the entire unit out about 1 inch exposing the screws at each side of the microwave that hold it in place.
Snapped off the top control panel which exposed the wiring connecting the control panel.
Unplugged a couple of wire harness units to free the control panel.
Be sure to label the units to know which goes where during reassembly.
Remove the microwave unit from the housing and place it on its side.
Remove the metal plate that houses the motor. 4 screws hold the motor in place. Disconnect the 2 wires from the old motor and you are ready to install the new motor. Be sure to TURN OFF THE POWER to the unit at the breaker box and remove the turntable from inside the microwave.

I took the new tray out of the box and placed it in the microwave oven.. No tools needed.

I put the tray in the microwave???? Pretty easy.
