Question about Pioneer DEH-P840MP CD Player

Open Question

No power on DEH-M840MP

Years ago I pushed a button to lower the front panel and get access to the rear panel. Once the front panel lowered it just died with no power. I sat it aside and forgot about it. But would now like to fix it if possible. I wondered if it could be the flex cable that I have read about?

The of the speakers is not important, but the impedance is. Check the impedance of the speakers using an ohmmeter and compare that to the spec for the head unit. Checking your maunal, which I found here: http://a248.e.akamai.net/pix.crutchfield.com/Manuals/130/1301300MP.PDF
your speakers should have a minimum of 4 ohms impedance. For more info, please read this post:

How to take off control panel on kenmore 970-c85092-00 dryer. dryer runs but no heat


Hello there and thank you for choosing fixya
Here is the full repair breakdown for you
Whirlpool and Kenmore style dryers - how to take apart: disconnect power first - Many dryers that I see have the two piece front, but some are the full front with no lower access panel on the bottom front ( see paragraph below ). The lower panel can be removed by using a straight screw driver to pry it off the upper clips, place screw driver in the middle top area ( below the door opening ) and "pop" it out towards you, sometimes you may have to do this at the side top corners of the lower panel as well. Once un-cliped from the top clips, the panel will have to be lifted up off the lower clips towards you. Once the lower panel is off, you should be able to see 2 screws on the bottom corners of the door panel, loosen these 2 screws off a couple of turns but do not remove them. From here you can see the idler pulley, motor, belt break switch and part of the belt. To go further in the disassembly, lift the cover from the lint filter or if yours is the one with a filter and cover together, remove the whole filter. You will see 2 screws under the cover/filter, remove them. Now, you will need a putty knife or a thin shafted straight screw driver to remove the top panel. Push the putty knife or screw driver here to "pop" the front top clips. The top panel will hinge back towards the wall and can be left there. Just inside the top of the front panel, you will see 2 screws, remove them. You will see the wires for the door switch on the right side, remove the metal clips to allow a more loose wire harness, hold the drum up slightly in one hand and tilt the top of the front panel towards you, you can now lift it off of the screws that you loosened earlier and place it on the right side of the dryer cabinet. On the dryers with a full front, use the same directions but you can ignore the lower panel and the loosen the screws parts. The front will lift off of 2 clips about 6 inches from the bottom and again be placed on the right side of the cabinet. You should undo the belt from the idler pulley and motor pulley, now you are ready to remove the drum. Just grab hold of both ends and lift it out. This style of dryer also has a rear access panel, you can see the operating thermostats, heat element connections from this point.

How do you clean out the filter on a whirlpool duet sport washer?


Prop up the lower front edge of the washer or cushion the rear top edge with cloth and lean the washer against the wall for easy access to the three screws securing the lower front access panel to the cabinet. Remove the screws and pull down the lower front access panel to remove it from the cabinet.

Place a shallow pan or lay a towel under the filter to catch the water from the pump. Unscrew the filter from the pump assembly and drain the water. Clean the filter and screw it back into the pump assembly. Slide the lower front access panel up back into the cabinet and secure it with the three mounting screws.

Front buttons . Remove the lower front speaker covers/panels by pulling . Then unplug connector ZF to the keypad . Then wait 3 minutes and try to turn it on with the remote . You may have to remove the access panel to find connector ZF (just follow the wiresdown from the front keypad). Don't touch , turn or break anything else while inside the access panel!
Let me know if that works

KA dryer has been running without a lint filter. Other owner. I need to know how to take off the front and back panal to clean inside due to fire hazzard. Mdl # KGYE800TWHO . Need schematic drawing. I am...


Disconnect Power. Lift Cover on lint filter. Remove two Phillips screws taking care NOT to allow them to fall into the blower housing. Next, place a putty knife in the space between the upper and lower panel at the front of the dryer about 4 inches in from either side to push up the retaining clips while pulling on the lower panel. This will release the lower panel and give you full access to all the main components and most internal areas needing cleaning.

The only area affected by running with no lint filter is accessed by removing the rear panel. With rear off, the filter housing on the left will have several 5/16" hex head screws to be removed for access to the blower wheel and housing interior. With screws removed go to front and insert putty knife in the seam between the top and front panels about 4 inches in from both sides. Lift top at same time and raise when disengaged.The filter housing can now be moved sufficiently to vacuum the interior from the rear removing any large foreign objects first.

You have now cleaned all the dryer areas that need cleaning. Don't forget the airflow through the vent line of the house.

Reverse the above process to reassemble unit. Good Luck.

Push Button to start and nothing happens.


Hi, The first thing you want to check is that the dryer has power to it. Then check the non resetable fuse. On most models the fuse is located in back of the dryer behind the rear panel.
Once you remove the rear panel, you will see the fuse located on the blower housing (White in color). Take continuity on the fuse. If the fuse has continuity, it is ok. If you an not access the fuse from the back, remove the front lower panel and the fuse is again located on the blower housing.
Other possibilities are door switch, timier, & motor. The fuse is most common problem!!
If I can help further, please let me know.

Thanks
Vic
