WGD6400SG0 Whirlpool Dryer - Instructions

Used putty knife to release catches on dryer top. Removed two screws in Lint Filter cover. Used Nut driver to remove the screws holding the front on. Removed the drum and had easy access to all the parts I was having trouble with. I believe the real problem was the Idler pulley but since I was already there I replaced the drum rollers also. While drum was out I vacuumed the inside of the cabinet. After parts were replaced i put everything back together in reverse order. Very Easy

Well, here's the rub...in order to find out what part I needed to order, I needed to take the dryer apart to where the gas controls are, and there on a sticker was a part number for an LP conversion kit. But, in order to get to that gas valve unit, I fumbled about figuring out how to take this brand new dryer apart, since there were absolutely no instructions whatsoever in the owners manual. And once apart, and pretty much all apart, I wondered how it would be that the Maytag repair man would be so lonely, as he'd have plenty to do.
However, the kit had great instructions as to how to take it apart and change out the orifices.

Getting to any of the parts in the Maytag dryer is easy. Tip the dryer back and slide a 4 x 4 block under the front edge. You remove the whole front panel after you remove two screws at the bottom corners of the front panel. You need to tip the dryer back to get a screwdriver on the screws. Swing the front panel up to release the top of the door panel from the top. Watch the short wires to the door switch. Unhook the door switch wires and move the front panel out of the way. The timer on the top is accessed by re-moving two screws along the top edge. There are four screws. Remove them all and tip the top of the front panel forward. You then see that two screws hold the panel and the other two screws just hold the trim.

The dryer started normal. The drum motor run when the start button was operated. The fluff cycle operated normal to indicate the timer motor was OK. On the dry cycles, the igniter heated up. The gas came on. The dryer run for some period of time and then the flame went off. The thought was that the low temp cycle thermostat sensed the dryer was hot and thus switched over to time the cycle to its end. However, the low temp cycle thermostat tested good with a meter when the sensor was removed from the dryer and heated with a light bulb. Burnt contacts in the sensor were a possible problem. I also though the radiant sensor may be bad and not recycling after it got hot. After time, the igniter would cycle on but the gas flame would not come on. I thought the radiant heater might not be tripping the secondary coil on the gas valve. The gas valve coils tested good. I was checking them cold after the dryer had cooled down. I ordered a number of parts.

I got lucky and did a test on the coils while the dryer was still hot. One of the coils in the dual booster holding coil was going open when hot. When cold it had enough continuity to let the gas valve cycle on once. After the coil got warm it went open and shut the gas valve off. When the coil did cool off, it again had continuity. I was about ready to trash the dryer when I finely found the problem. I am happy I persisted and worked the problem through to a solution. I purchased several extra sensors but saved money in the long-run. I rate this problem at the high end of complexity for the do-it your self home owner to solve. The problem was an easy fix once the real problem was found. Only 4 screws and 3 push on wire connectors (two were on the front panel for the door switch).

Checked four thermocouples all showed continuity with my multimeter so they were all good. I'd read that the coils commonly went out and that these were the symptoms. Hey, it's very simple in there. Not much else could be wrong. I had a Maytag repairman come out. At first he said the problem was a blocked vent. I knew he was wrong. Then he said one of the thermocouples went out. It was $80 for him to come out. It turned out that his second diagnosis was wrong too. To repair the dryer by Maytag would have cost me $240. I gave him $80 and bought the coils for $37. They are EXTREMELY easy to replace: two screws held a bracket that held two coils. With the bracket off, I took off the old coils and slid on the new ones.

Followed instructions, except to advoid sharp edges, and completed the job in under an hour.

Just follow the instructions the one was provided with Maitanace kit we bought from you.

very easily

Half of my pulley was broken off so there were no wrench flats to take it off. I was able to remove it using Channel Locks and the 7/16 wrench shown in the video.

Hint: Use a one gallon ice cream bucket to hold up the drum while connecting the belt. It makes it much easier and gives you more clearance.

I'm still waiting on my idler pulley. It arrived at Fed EX depot in Tracy CA on December 14th and has still not been shipped. So it is pretty fucking hard for me to install it! Maybe if you had customer service that would answer their phones or reply to my Emails would be helpful

Take door off dryer (unscrew four screws). Lay door on flat surface. Using glue provided glue down new seal. Put dryer door back on and you're done!

Everything worked perfectly---thanks to the suggestion of your call center agent. She suggested that since the replacement door handles were no longer available, I should consider repainting them--it worked like a charm. Please tell her she was a life saver. We rent that house in Fl and my returning tenants had complained about the discoloring refer handles. Thank you

removed front of dryer located igniter removed two screws disconnected wires then put new one in also replace thermal fuse and thermostat on back of dryer works great.

I suspected a faulty igniter and disconnected the cable to the igniter and measured the resistance of the igniter and found it to be 70 ohms then I checked the voltage at the same cable towards the power source and found it to be 25 volts ac which should be 120 volts ac. Next I checked the radiant flame sensor and found it to be open (it should be a closed circuit when cold). I removed the flame sensor (with the power off) using a small box wrench and found a broken lead. Replacing the flame sensor solved the problem.

Replaced both Coils. Purchased M Series coils much less expensive buying coils together instead of seperately. Problem solved.

Took everything apart, replaced the igniter flint, and still didn't get heat. Then found out the thermal sensor wasn't running a electrical current through it with voltmeter and just replaced that, now it we have heat again!
