MDG6657BWW Maytag Dryer - Instructions

first, I unplug the power supply of the dryer then I removed the two screws at the bottom of the dryer then pulled out the front part of the dryer,unplugged the blue & yellow wire for the on/off switch for the door,at the back of the dryer I unscrew the pannel for the belt,disconect the belt,and I unscrew the four screws on both side of the front pannel to remove the front cover of the drum. Once I removed the front cover of the drum I can now remove the drum itself to access the drum support roller. I unscrew the rollers then replace it with the new once. It was an easy job.
Thank you.

Removal of old lint collector and replace with new one.

No problem at all, just took out the old one in front and slid in the new one.

PartSelect showed seven different possibilities why the dryer wouldn't heat. I removed the two screws to remove the bottom panel and turned the dryer on and noticed that the heating element that ignites the gas was working fine. This meant that it was not getting gas so it could be the gas valve or one of the two gas valve coils which are located on top of the gas valve. I borrowed my neighbor"s ohm meter and touched the two probes on the coils terminals to check for continuity and found that one of the coils read zero. I then took both of the coils out by removing two screws and tested each coil again. One coil read 500-850 and the other read zero. This meant that it was no good so I called for the part and received it in three days. I reassembled the parts and turned the dryer on and it fired up after a few seconds. It works as good as new. The part plus shipping was less than $30. My repairman would have charged me $150-$200. While the dryer was apart I gave it a good cleaning with a vacuum and a toothbrush in delicate areas. I also removed and cleaned the lint trap housing by removing two nuts. I didn't know much about gas dryers, but thanks to PartSelect I easily fixed it myself.

If everything else is working ( tumbler and timer ) except for the heating. Your first bet would be checking your flat style igniter. Mine was cracked, something that I wouldnt have seen unless I had taken it off. Because of the crack no current was being passing through, therefore the igniter wasnt heating to its amber color. Since there wasnt any current the gas valve was doing its job by not allowing any gas to blow out. Dont worry about turning the gas off just disconnect your elecrical outlet. Remove whole front dryer panel by taking 2 front bottom screws out (philip screw driver). Dont pull to hard because there are two wires connected to the panel and dryer that you will have to disconnect. When you get to the igniter disconnect wire plug and use your socket set to loosen the single srew on the igniter, gently wiggle it out by just handling the white ceramic part of the piece, and replace new one in. Just remember to be careful since the dark part of the igniter that heats up is real brittle.

There was no problem with lint build-up within the dryer & the exhaust vent. I removed the gas cycling thermostat & thermal fuse from system & dryer still was not operating correctly. The radiant sensor & hi-limit thermostat both seemed to be operating correctly. That left either of the two coils as the culprits. I replaced both coils & the problem was corrected.

Timer wasn't working on the regular cycle so I replace it with a new one from partselect. It still wasn't working so I ordered and replace the cycling thermostat, the thermal fuse I also cleaned the vent and dryer it still didn't work so I read the diagram for the electrical and found that a coil for the gas valve is line with timer. I ordered the coils for the valves, replaced both valves and tested the dryer and it work just like when I first bought the appliance.

Determining the problem was the hardest part. With multiple parts (coils,thermostats...)possibly causing similar symptoms, I narrowed it down to the two coil valves.
Un plug the dryer. Remove two screws at the base of the front panel. Turn the front panel 180 degrees to avoid disconnecting the door switch. Gas valve with coils on top are on the right in front. Remove two screws in bracket holding coils, disconnect the wires, replace with new coils and reconnect wires. One coil has 2 terminals the other has 3 no chance of crossing the wires. I used an offset/right angle screw driver for one of the bracket screws due to close proximity to the drum. A stubby phillips head will work. You can check the burner operation with the front panel off as long as the door switch is still attached. Swing the front panel around and lift back into place securing with the two screws. Dryer works fine now.

removed door, removed screws to lift top panel, removed screws that held old baffles, replaced with new baffles, took off front panel and cleaned out excess lint while I was in there.

FIRST unplug dryer from electrical source, CAUTION, the top of this dryer does not open with clips, do not pry on top to open! On the front of the dryer look under the lower panel, and find two screws, one on the left side, and one on the right, remove these screws, and pull slightly down on panel to remove. Behind this panel find two screws holding the door panel, one on the left, and one on the right, remove the left, and support the door panel while removing the right side. Gently pull the bottom of door panel outward, and the clips on top of door panel will unhinge from top, carefully rotate left side of door panel to floor, and note the wire connections on switch, and orientation of switch, then unplug wires, and move door panel to a comfortable working positon. Door must be open to remove switch, then depress the two plastic retaining keepers on each side of switch, and push switch through toward door. Replace with new switch, reconnect the wires, and reassymble in reverse order. Remember, door assymbly must be inserted in dryer top at an angle, and then bottom rotated downward, and bottom panel nylon guildes inserted into door panel bottom.

The door had always opened with the wrong swing and it wasn't til I needed to repair this that I noticed you could change the swing. I changed the swing of the door and then noticed that the clip was included on both sides so i did not need to repair the catch. I still have the part so when it breaks again, I can just pop it in.

I removed the two screws holding the front panel to expose the lower works and verified the heating cycle failure. After a check of the vent system, checking the sensors for continuity and coils for resistance, I retired to the 'net for support. Accepting the general consensus that the most frequent, common and likely failure to be the coils, I rechecked them with the meter and found the two pronged coil to have significantly more resistance than the three prong coil. That was enough evidence to point to the coils. While I waited for the part to arrive, I replace the vent ducting. When the parts arrived I removed the two Phillips screws holding the coils, removed the old ones, installed the new ones, replaced the bracket, put the front cover back on and in less then ten minutes clothes where drying.

My wife and I had put up with this silly switch for months where we would continually pull and pull on the switch which used to take only one pull. I found PartSelect on line and chased down the part number I needed. Unfortunately, I misread the correct part number which was different for different serial numbers within the same model number. PartSelect solved this by shipping me the correct one after I discovered my mistake (the part originally sent would now start the dryer as it was supposed to but the timer didn't advance). Anyway, I had reviewed the other "installation instructions" available. It was slightly unclear to me, from reading the other descriptions, of how to remove the timer knob. The knob is in three (3) parts. To remove it, take a pocket knife or other very thin blade and slip under the silver cap and gently pry it off (it's held by four plastic studs which engage into the middle portion of the knob). Once the silver cap is off, remove the middle portion and the inner white portion by lifting straight off. Then, remove the three #10 star screws at the top of the control panel. The control panel then pivots toward you and you can lift it out of the frame to make access to the timer even easier. Next, gently remove the cable harness on the left side of the timer control assembly by depressing the tab in the middle of the connection piece and rocking gently back and forth (it is fairly snug) until you have disconnected the cable. Next, depress the plastic tab on the left side of the timer assembly and gently slide the whole timer assembly to the left (it has a plastic tab on each of the other three sides that slide under plastic holders). Insert the new timer control assembly and simply reverse all of the steps listed above taking care that the plastic feet on the new timer control assembly are engaged under the receiving plastic keepers. This is a really easy repair and took me less than 15 minutes to complete.

I noticed that the igniter would glow white hot for about 5 to 10 seconds, but would only ignite every once in a while. I decided that it was probably the gas valve that was bad. I removed the wires to the igniter and valve, and removed the two screws that secured the valve to the frame. I accidentally bumped the igniter as I removed the valve from the dryer - it broke! The igniter is extremely delicate, be careful not to touch it. When the new valve and igniter came in, I swapped some of the mounting hardware and installed the valve and igniter. I reattached the wires. The dryer fired up immediately - it was an easy fix.

First, I read reviews on this forum. Great help! I was betting, from previous reviews, that it was a drum roller. I took everything apart prior to ordering any parts. Sure enough, one drum roller was seized on the roller shaft. Decided to replace all rotating parts (rollers,shafts, belt, idler pulley) while everything was apart. I also took the opportunity to clean out all of the lint (there was a lot) from the motor and intake.
Parts were on my doorstep in two days. The dryer is like brand new. I could do this job again in less than an hour. This was money and time well spent.
