RM778PXT0 Whirlpool Microwave Oven Combo - Instructions

I numbered every part. ex: 1 L., for first part removed left side. I used a magic marker to circle the holes and wrote the number of screws used on the part, set the srews in a separete place, so that I new where these screws went to. The cleanup was pretty time consuming, but I was able to keep my stove, when every repairman I called to fix my stove told me I was better off buying a new stove. ($600.00 stove 2 years old)Please Note: The insulation blanket needed for the entire stove is two pieces, the sides and top are one part # and the bottom and back, are another part #. I did not know this. I just purchased the top and sides. I got lucky, the back and bottom were still in good shape. So I guess I should have read the description of the part more carefully to see what it covers, before I ordered it. It took two people two hours to do the work, it was really nice to have an extra set of eyes, to remember what direction pieces of metal from the stove went. I would do it all over in a heart beat instead of buying a new stove.

This product comes in a bottle with a brush like Liquid Paper. It goes on incredibly easy. A second coat might be needed. I wanted to prevent rust from setting in so I covered the scratches and dings. The paint is a little brighter since my washer is 10 years old but it still looks great.

Ordered a new door frame morning of March 25.
Part arrived the next morning and by that afternoon, the
replacement was complete. Only four screws held the frame.

Everything worked perfectly---thanks to the suggestion of your call center agent. She suggested that since the replacement door handles were no longer available, I should consider repainting them--it worked like a charm. Please tell her she was a life saver. We rent that house in Fl and my returning tenants had complained about the discoloring refer handles. Thank you

Just pulled the old support out with pliers and installed the new one which snaps in. Not sure why the support melted as it has been the same one twice now. Keep extra support clips on hand, but no need as Parts Select had the new ones here next day.

The microwave is the upper unit of combination microwave & conventional oven. Disconnect power to the unit. Slide unit out of built-in cabinet to expose the top shield of the microwave. Remove 5 screws holding top cover in place. Remove cover, which exposes the belt reel and drive motor. Install the new belt by threading it on the drive motor pulley, then walk the new belt on the stirrer pulley. Replace the top cover and reinstall the 5 screws. Reinstall the combination unit in the wall cabinet. Reconnect electrical power. Task Complete. The belt just seem to die of old age about every seven year. Without the wave disperser operating, the microwave oven does not give even heating.

Substitute the broken parts for the new ones!

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

I didn't. Don't know how to get to light bulb to change it for this specific model

Removed the ice brucket,
Removed the light shield by releasing one screw using a nutdriver.
Replacing the bulb and reinstalled the light shield.

Your web site is one of the best and most helpfull service sites I ever used. Just wish that in the future you will ship parts overseas.

removed seven screws to take door apart and replace button. Glad that you still had the part for a 25-year-old unit.

Well, when you put the back cover on and screw it down make sure you have nothing touching the white wire leading to the oven light. I did and it blew the push switch when I threw the 220 breaker. Actually, the light was on when I came in the room, but when I pushed the switch on the front panel it sparked in the rear and popped the breaker. Then I saw the short and when I tested the switch it would not click. The install was fine.

With the Perfect Replacement Part, the 'installation' was simply putting the new knob on!..:-)

The old knob pulled off easily. Its stem had broken. Examine the new control knob. Its stem has a protrusion on it which fits into the grove on the shaft of the oven's function-control switch. (It would be the same for the temperature-control switch, also.) The new knob slips on easily when properly aligned. You may want to use some gunk from a breakfast cereal box (the clear gummy gunk that is used to hold two cereal boxes together, when sold as a pair) to help the new knob stay on. Using whiteout or paint, mark the end of the ridge on the knob that points to the switch position, so that you can easily tell which way it's pointing.

This microwave is the upper unit in combination with an oven. Microwave portion is Model RM288PXS. Cut power at breaker box. Remove metal frame around 2 sides and top, (5 screws). Remove 4 screws on bottom, whicn anchors the unit to the frame.Remove contol panel (2 screws at top) and swing down. Pull out female electrical socket at bottom right back in conrol unit space. Now pull out microwave from frame about 6-8 inches. This provides access to pulleys on the motor and wave disperser. Put on belt. Reverse the above procedure to finalize the repair. This is the 3rd time I have had to replace this belt. They last about 6-7 years. Without the wave disperser , the microwave does not provide even heat.
