How do I remove the touchpad - Cuisinart CMW-100 Microwave Oven

Check to see if the touch panel is connected to the main board via a ribbon cable. If it is, carefully remove and clean the end that attaches to the circuit board. Electronic contact cleaner works well for this.

The touch pad is more than like the problem. This is common. Try removing the ribbon connector and reinserting it back in the receptacle. If this doesn't fix the problem then replace the touch pad.

1. Controller is confused A power surge or random non-reproducible action of the universe may have resulted in the controller's program ending up in an infinite loop. Pull the plug for a minute or two to reset it.
   
2. Defective Interlock switches This can result in the controller thinking the door is open and ignoring you.
   
3. Cleaning Cleaning solutions (spray cleaner) may have gotten inside and shorted out the touchpad or controller. If this happens remove the touchpad, let it air dry for a few days, and then attach it back on the microwave.
   
4. main control board to ensure that a shortage has not occurred. If the part is defective then it will need to be replaced to prevent continual shut offs. If this is not the issue, the next step would be to check for a faulty touchpad.
5. Touchpad/Control panelIf the control board is not the issue and your microwave continues to shut off after running for only a few seconds, the next thing to check is your touchpad, which is also known as a control panel. Although uncommon for this issue, symptoms are usually that the display and some buttons are working properly; however, when selected some buttons are not functioning. If this is the case the touchpad will need to be replaced.

Every microwave oven I've seen has the touchpad permanently glued to the controller housing/front trim piece. To get this off, remove the top/side cover piece, then look for screws that hold the controller housing to the front of the oven. On some models, there is one screw at the top. After you remove that you can slide the controller up to unhook it from the oven frame. If there is a push-in door release latch in the housing, there is probably a screw or two at the bottom as well.

Now here is where it gets interesting. There is a flexible printed cable from the touchpad to the controller circuit board. To detach it from the board, you must first unlock the connector. There is a flanged collar on the connector. If you pull the collar up as if you were going to slide it along the cable (it only comes out a millimeter or so and hits an internal stop; it's part of the connector and is not supposed to be removed), that unlocks the connector and the cable slides right out. If the cable doesn't slide out, make sure you have both ends of the collar up to the internal stop. Now you can remove the screws that hold the controller onto the keypad and the removal process is essentially complete.

To reinstall the ribbon, slide it all the way into the connector and push the locking collar back down. Make sure the cable is in square and straight or the keypad may not work properly.

Caution: handle the controller board only by the edges. The controller chip(s) is very vulnerable to static electricity damage and can be ruined by a spark to the circuit that is too weak for you to feel the discharge. Avoid touching the contact area of the touchpad ribbon while inserting or removing it. (If you need to clean the ribbon contacts that go into the connector, it is OK to work on those while the ribbon is disconnected.) In some ovens, the controller chip is mounted directly on the board and covered with a soft rubber compound. These are especially delicate; it's too easy to break the fine wires inside that connect the chip to the board (but they're cheap to make!).

I am not familiar with the Whirlpool microwaves; however, I just had the same problem with an LG over the range microwave. Several of the positions on the touchpad quit responding to touch. In our case, it was the touchpad itself that was the problem.

The touchpad on our microwave was held in place with adhesive. We pulled it off and replaced it with a new touchpad. Everything works now. The only complication is getting to the connector which carries the signals from the touchpad to the microwave controls. We had to remove and dissassemble the door to get to that connector.

The touchpad cost about $26.00.

The touchpad has its own fuse which has probably blown due to a surge perhaps related to the turning on of the fridge. Removing the cover from a microwave is potentially lethal due to the large capacitor to drive the magnetron. However, this is usually well away from the front panel. If you do venture in you should first unplug the unit and when the outer cover is removed, discharge the large capacitor with well insulated pliers -= otherwise keep well away from it. The fuse you are interested in is on the pc board behind the touchpad. Replace it with exactly the same fuse (usually a slow blow fuse).

We have an LG LMVM2075SB over the stove microwave that we purchased in December, 2007. A few weeks ago, several of the positions on the touchpad stopped working.

I assumed that the problem involved the touchpad itself. I ordered a new one (Part number MFM37134802 - $25.30 plus shipping), and we installed it today. This solved the problem.

The installation was not simple. The door has to be removed and disassembled to enable you to get to the connector that connects the touchpad with a circuit board. We heated the old touchpad with a hair dryer and pulled it off (after disconnecting the connector). The new touchpad comes with an adhesive backing. You have to be very careful in placing it because the adhesive is very strong. The touchpad fits in an identation, so the placement of the new one must be perfect.

Failure of the touchpads on these LG models seems to be a common problem. It sounds like a design problem.

1. Unplug it from the outlet.
2. Remove any screws and unlatch any tabs in the vent grille.
3. Pull up and/or out to remove the grille.
4. Remove the screw now revealed at the top of the control panel assembly.
5. Lift up and/or swing down the control panel assembly.

You can usually find helpful exploded view diagrams and order parts by entering your full model number here.

There should also be a "mini-manual" hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting & testing.

If you still have trouble, please reply back with your model number.

We repair these control panel assemblies.
