MDG7658BWW Maytag Dryer - Instructions

Note: You may want to consider replacing the 2 Drum Support rollers at this time (while your in there)

1. UNPLUG YOUR DRYER FIRST.

2. Using a phillips head screw driver - Remove 2 screws that secure the dryer door hinges to the frame, Lift door very slightly to unhook hinges and pull out door with hinges attached as straight as possible, set aside. Remove the 2 plastic tabs from the opposing side of the door hinge also secured by screws.

3. Remove the front panel (panel is shaped like a football goal post) by tilting out the top ends of the front panel toward you, then lift up to remove panel from the bottom metal retaining tabs.

4. Remove the 2 hexhead screws from the 2 retaining clips (security hooks) that secure the top
of the dryer closed.

5. Systematically remove the hexhead screws from the rest of the front of "shroud" (it holds (suspends) the drum in place between the front and back of the dryer).

*** I didn't disconnect any wires, I carefully swung out each piece that had wires attached, propped up those parts vertically ensuring no strain on the attached wires. Others may want to disconnect wires to avoid breaking or damaging them.

6. Vacuum out any dust/lint that may be present.

7. Draw a quick diagram of how the underside of the belt is threaded on the idler pulley and motor pully first. Release the tension of the belt from the underside of the drum. The easiest way is to push the idler pulley arm away from the belt and slide off the belt from the idler pulley and motor pulley. Slide the drum out.

8. Remove the hexhead screw from the bottom of the idler arm. Disconnect from retaining spring.

9. You may only need to replace just the Idler Pulley Wheel. I recommend replacing as a "unit" the Idler Pulley Wheel, Idler Arm, Ring-E and Idler Shaft Washer(s) - then you can just swap out the old one for the new one.

10. Reassemble

(When reassembling the belt - place around drum first and slide drum in place. Now from the underside-place (drape) belt around the motor pulley (it will be very loose) Now push the idler pulley arm toward the motor pulley, engage the left side of the belt around the idler pulley and slowly allow idler pulley to increase its tension on the belt) You can test manually by rotating the drum by hand to ensure proper movement.)

I removed the front of the dryer by removing the two screws on the bottom of the front panel, disconnected the door switch wires. I removed the connectors from the coils on the gas valve, the heat sensor and the igniter. Loosened the gas line at the valve. I removed the screw holding the gas valve and burner assembly and removed the assembly from the dryer. Remover the screw holding the burner to the valve, and removed the igniter. Replaced the burned and reconnected what I had removed. The reason the burner didn't light was due to the gas deflectors being burned off of the burner, If the igniter, sensor, and coils check out OK , check the front of the burned to besure it is deflecting gas to the igniter

I removed the front panel of the dryer by removing the 2 screw that secure it at the bottom and pulling upward to disconnect the cover at the top. I then removed the two screws that hold the metal cover that secures the 2 elements in place. I disconnected the wire plugs from the 2 elements, removed the 2 elements and replaced them with the new parts making sure to place them in the same positions as before. I then replaced the housing cover and tightened the screws. Then I replaced the front cover of the dryer.

After replacing all the other fuses and sensors I finally replaced the Radiant Flame Sensor and it is working perfectly.

After replacing the other parts and the heat still not coming on I read somewhere that the Radiant Flame Sensor is a normal closed circuit and when I checked with a meter it was open. I would have saved a lot of time and money if I had read that earlier.

Turned off gas and unplugged dryer
1) Removed bottom front panel
2) lifted top panel up like a car hood
3) Removed door springs
4) disconnected electrial connections to door unit, removed door unit
5) removed drum, scraped old felt from drum
6) glued new felt with a very strong glue (nanoglue or gorilla glue, same thing), let it dry overnight
7) secured back inside panel, replaced drum and put dryer back together.

My 20 year old reliable Maytag 512 lgp dryer was not heating anymore. At first the heating element would glow red but not hot enough to ignite the gas. I replaced the element and it worked for a few loads but then stopped reigniting after the first cycle.

After some research and diagnosis (checking connections, amperage flow on each electriical part, etc.) I determined that the two coils were faulty. I ordered parts and replaced them (easy to do) and it worked again, for another few loads. Then nothing worked. The coil did not get hot and I did not hear the clicking sound that initiates current flow to the ignitor through the coils.

I checked the coils and ignitor again, they were fine. Frustrated, I called in a repairman to diagnose the problem. $55 and 15 min later he narrowed it down to the High Limit Thermostat. To demonstrate he bypassed the thermostat by directly connecting the two leads together and the ignitor fired right up.

His price to replace the thermostat? $45 part plus $130 labor. I bought the thermostat online for less than half his parts cost and the labor took me 5 minutes. Simply unscrew the small screws with a small socket set or nutdriver and replace the thermostat. Just two connectors, real simple.

All in all it was very easy to replace the parts, just tricky to diagnose unless you are good with electrical work.

We tried replacing the door switch first, still didn't start. Next we tried the thermal fuse and it turned on and has worked ever since.

Instructions were great. Very step by step. It could not have been easier. Repair saved me a $100 service call.

popped out old female clasp on dryer itself with screwdriver, undid 2 screws on dryer door and door handle with phillips screwdriver, popped in new male clasp part, put door knob back on and put the two screws back in door and it was all set to go. Less than 15 minutes to do. Better than new and wife is happy. No more duct tape holding door closed now.

Opened front panel .Tested both coils on gas valve.
Found no continuity on one of the coils. Replaced coil,
dryer works like new.

I just inserted the door catch, which by the way fit in perfectly. Thanks. Took 5 seconds to repair.

I tried a new dryer timer first upon the recommendation of a local appliance place. They stated that since the dryer was not working in either timed dry or Intellisense dry modes, more thank likely, it was the timer. That did not fix the problem so I tried the sensor assembly next. Simply removed the housing by removing the three screws, snapped out the old one, snapped in the new one and everything works.

pulled the motor and replaced it and not having any issues since.

Took out two front Panel screws and removed the panel. Removed Gas solenoid coil holding bracket by removing two phillips head screws. Disconnected the coil leads. and removed the coils. Connected the new coils to the leads and set in place. Replaced the holding bracket and the two screws. Replaced the front cover and the two front cover screws. Piece of Cake!

Removed screws in hinges and on opposite side inside the door to remove the front panel.

You can put the door back on at this point to run the dryer with the burner exposed. At this point I could tell that the igniter was working and the gas valve would occasionally work so that burner would fire. The valve only seemed to work when everything was completely cooled down. I first replaced only the solenoid coils on top of the valve, this did not fix the problem. When I replaced the entire valve the problem was fixed.

Replacing the valve is easy.

1) Unplug dryer from wall outlet
2) Turn off gas supply cutoff valve
3) Remove door and front panel
4) Unplug wires from solenoid coil terminals. There are two coils on top of the valve body.
5) Remove gas line from valve body.
6) Remove two screws which secure the bracket holding the valve body and burner nozzle to the bottom of the dryer cabinet.
7) Remove two screws which secure the valve to the bracket.
8) Reverse the procedure for installation of new valve.
