Make sure copier is unplugged. You need to remove the glass by removing the left side panel. Remove the two screws and remove the panel. Remove the glass. You should see a ribbon cable on its side with a black cover. Remove the cover. It provides access to the hole you should see. Slide the top to the left and remove the drum unit. While the blue top is up, remove the screw that holds the control panel secure. Lower the blue cover and remove the control panel. Be careful of the ribbon and unplug it. You should now see the access hole to get to the screws that secure the fuser assembly. Remove 2 left side covers by removing the three screws. The one screw you see at the front I remove to make it easier to remove the cover that has edges below that cover. Then remove the cover that is above the delivery area. Turn back the milar sheet and unplug the three connectors that are routed to the fuser. Remove the three screws and carefully remove the fuser assembly. Carefully reverse the procedure for the replacement fuser or rebuild the fuser assy by taking the fuser assembly apart. I hope this is enough to get you started in the right direction.

The front touchpad panel uses a ribbon cable to connect the buttons and lightd to the electronic control unit. This ribbon cable tends to corrode atvthevpointvwhere it passes through the door to the control unit. You will see a brownish rust on the ribbon cable. A new control panel appears to e around $135.

I had no lights on my control panel, eventhough power was good.
I replaced the control panel ($265 part), it worked for 2 weeks, then I now have the same problem.
Frustrated, I am probably going to buy new from a different manufacturer.
Whirlpool/maytag does not warranty electronic parts if you do it yourself.

Check power cord is plugged all the way in. Make sure GFCI plug is not tripped and button is set if it has one. Try unplugging the appliance from the power for a minute then plug it back in and see if that works. If those are good you could dis-assemble the front panel(unplug first) and inspect ribbon connector on control board. Make sure connector is fully seated and has not come loose. Look for signs of any tiny shorts across the connector. Could be a bad control panel board. I had a similar problem and it turned out the ribbon connector for the control panel had shorted. I had to buy a new control panel online(ribbon connector could not be repaired).

There is a probelm with the control panel. You can fix it for about a penny. The panel has a printed ribbon cable that plugs into the relay board. The ribbon cable is actually two cables pressed together, which can be seperated by simply lifting them apart. The ribbon cable has a defect in that the plasic insulation is defective, causing the leads between the two ribbons to cross, or short circuit. Simply place a thin sheet of paper between them, and make sure you push the paper down all of the way to the plastic housing, fold over the edges around the cable, you are done.

take the control panel off and re-seat the ribbon cable back on the board if that does not change anything replace your control panel.

• Stuck remote control button. Check all remotes. check LED on receiver.
• Staples around Multi-Function Control Panel bell wire could be cutting into that wire. Remove wires from opener and test. Replace staples causing intermittent short.
• Multi-Function Control Panel could have sticking door control push bar. Remove wires from control panel and test. Replace control panel if defective.

A blinking indicator light means the thouch key that geos with that light is stuck. So yes you need a control panel since the touch pad assembly is installed on it at the factory. I would have them put your old control board in with the new touch pad. It should work but sometimes they both go out.

about the only thing to try would be to remove the inner door panel to get to the control bd then you will see a mylar ribbon looks like a fat piece of scotch tape pull up on the plastic connector that holds it in and pull the ribbon out then get a clean pencil eraser and gently clean the ribbon and put it back in dont forget to push the locking tab back down then try it again and let me know
