DG7400 Maytag Dryer - Instructions

Removed the screws and took the door off then took the front panel off and popped up the top. Then pulled the drum out. Took snap ring pliers and removed rollers and replaced with new rollers then vacuumed all lint from machine and reversed operation to put everything back together. Operation was a total success!

Unplug the dryer and remove the front panel (two screws at bottom of the panel), being careful of the door switch wires attached to the front panel. Using an ohm meter, I checked the ignitor for continuity and found it was open (should be 50-100 ohms). Make sure to check the solenoids on the gas valve. When the igniter goes bad, it will usually burn out the valve 1 solenoid boost coil (the one with 3 terminals), which was the case with my dryer. The solenoid coils are held in by a bracket with two screws (series 01 dryer) and are easy to remove and replace. Be careful replacing the igniter as the heating element is VERY fragile. Take the time to vacuum out all of the accumulated lint and dust inside the dryer while the front panel is removed, including the lint trap and duct. New igniter and boost/hold solenoid fixed the problem.

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.

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

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.

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.

First I unplugged the machine. I removed the two screws in the front panel and tilted the bottom of the panel out unclipping it at the top. I removed the lint duct whichis held in place with several 1/4" hex head screws. Then I removed the blower cover, also held on wth 1/4" hex head screws, exposing the blower wheel. Using snap ring pliers I removed the snap ring at the end of the motor shaft. Using needle nose liers I removed the spring clamp around the center hub of the old blower wheel and pull the blower wheel off the motor shaft. After cleaning as much lint out as I could I put the new blower wheel on the motor, secured with spring clamp and snap ring. Then I put the blower cover and lint duct back on and put front panel back on.

Followed the instructions on the video, and saved 500 hundred dollars. I was already shopping for a new dryer. Thanks so much!

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

Replacing the blower fan took way too long, like 4 hrs, because I didn't know how to disassemble the dryer and get to the problem. Replacing the idler bracket and assorted retaining rings and washers was fast, something like 1 hour. Disconnect the power cord, exhaust hose, and gas line. Remove two screws at the bottom of the face of the machine, unplug the electrical harness to the door light, switch and ground and remove the front of the machine. Remove the access panel at the back of the machine and remove the belt from the idler pulley. Remove the four screws holding the front drum support assembly and remove the drum. Replace some old retaining rings and the spring washers on the drum support rollers. Around back assemble the idler pulley assembly with some new washers and the old roller which seemed in good condition. Put it all back together. About one hour.

Unplugged the dryer!!!! Removed two screws from lower front panel. Pulled bottom of front panel forward which allowed clips holding top of panel to release. Unlcipped wires attached to door switch on front panel. Set aside front panel. Removed 4 screws(2 on left & 2 on right) from the drum retainer ring. Set aside retainer ring. Removed thin metal cover protecting blower wires. Removed several screws holding blower cover. Note blower is located on lower left below the lint screen. Used snap ring pliers to remove snap ring securing old blower wheel(an external snap ring). Removed old blower wheel from motor shaft. Inserted new blower wheel on motor shaft. Replaced snap ring. Replaced blower cover. Replaced thin metal wiring cover. Replaced drum retainer ring. Reconnected door switch wiring. Replaced front panel. Done. A hint on the maytag dryer. If your drum wiggles out too far the belt on the drum might not stay aligned. There is a groove on the drum...the belt should NOT sit in this groove...it should ride on the drum about an inch in front of the groove!!!

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

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.

Using the instructions accompanying the belt I bought from you,I removed the casing an front support for the drum. I then tried to follow the instructions to install the new belt from the front and found it to be absolutely impossible.I saw that there is a removeable plate on the lower right corner of the back that,if removed, would expose the motor and idler pulleys that are the object of the installation so I removed it and,without much difficulty, installed the belt. One problem in doing so involved the belt's tendency to slide into the groove in the drum when manipulating it onto the pulley set so I enlisted the aid of my wife to hold it in place from the front while I successfully and rather easily did so.

Sans manual, I turned to the web to find out how to open up the dryer. Maytag uses two Phillips screws on the bottom front panel. Once removed, the front pulls out at the bottom and slides free from the top. Caution, wires on the left side of the front panel prevent total detachment from the dryer. A 1/4 hex screwdriver was used to remove the cover to the blower housing. Once the cover is unbolted attached wires prevent its complete removal and can be set clear of the blower housing. Pliers were used to remove a pinch clamp from the squirrel cage fan (blower assembly) and snap ring pliers were needed to remove the retaining snap ring. The fan was easily removed from the motor's rotor. The loose fan caused damage to the blower housing which I believe was the source of the original rattle. Once the fan had been removed, the housing was removed by using a 5/16 socket on the end of an extension. The replace parts were installed in reverse order and fit perfectly. Other work included the replacement of the drive belt for the drum. PartSelect was chosen because it had the parts in stock and could be shipped overnight.
