RM278BXV3 Whirlpool Microwave Oven Combo - Instructions

took out the old heating elments and cleaned the bottom & top of oven with out the elments in, which made it alot easier then put new ones in. They were very easy to do, just make sure you watch how you took old ones out and don't loose the screws cause you use them to put new ones in.

Open oven door. Still power to the wall, but all Knobs in "OFF" position. two phillips screws, pull old element back, and disconnect both leads. Put the leads on the new element and reinsert with two mounting screws. Simple.

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

The broiler unit had disintegrated at both connections. I removed the two screws in the top of the oven holder the unit, pulled out the unit, measured and ordered a replacement.

To replace the element, I pulled out the stove, removed the rear panel, located the connections for the broiler unit, remove parts of the old unit. I then attached the new unit to the top of the oven with the two screws, went around back and pushed in the two connections, replaced the back cover and replace the stove. It took about 30 minutes because I cleaned everything and sprayed bug spay (another plus for doing the repair myself).

I used a screwdriver, removed and reinstalled four screws. That was it.

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.

1. Turn off oven.

4. Pull element out to expose connectors.
5. Disconnect connectors and remove element.
6. Reverse procedure for installation.

grandson removed the two screws holding in the burned out unit and removed the two wires, installed them into the new unit and put the prongs into place. very easy and certainly very economic. delivery was quick and postage was reasonable. Thank you.

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.

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

I had previously partially removed the element and tested with multi-meter to determine that it was not working (open circuit). Repair procedure follows:

Turned off Power
Removed 2 retaining screws
Pulled element out part way
Removed 2 spade connectors supplying power
Replaced element w/new element
Reversed procedure
Tested Oven; worked fine.

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.

As soon the Bake Element has arive, I install it no more than 5 min... All I nedd was a Screw driver. It was so easy, Thank You PartSelet!

I removed the back panel, unplugged the wires, removed the 2 screws, replaced the element, plugged the wires back in and put the back panel back on. Now that I'm thinking about it, I guess I didn't even need to remove the back panel to replace the element.

Naturally the oven turned was off but for added safety I also set the breaker protecting the oven to the off position. Where the element attaches to the oven there is a small plate with two screws holding the element in position. Remove these two screws and then gently pull the element out 2-3 inches, which will expose the electrical connection. Using needle nose pliers gently pull on one of the wires to remove it from the element. Now remove the other and discard the old element. Simply plug the new element into those wires and screw the plate back into the oven. Now turn the breaker back on and you're done. Super easy!
