Dryer powers on but drum does not spin and no heat. Drum is free by hand and door switch is functional - light goes on when door opens.

If you can hear the motor running when you turn the dryer on but the drum does not turn, it may be that the belt has broken or the idler has come loose. You don't mention the make and model of dryer but most are driven by a long belt that goes from the motor at the bottom of the dryer over the drum. It is held tight by an idler pulley. Google "drum will not turn" along with your make and model so find out how to gain access to the underside of the dryer to make sure the belt is intact.

Maytag gas dryer mdg9306awa anits sounds like it wants to start but doesnot

that is the motor,try this,open the door,push the door switch in with one hand and spin the drum with the other hand while someone else pushes the start button,if by moving the drum the motor does start to run the motor is bad,also you have the neptune style maytag and i don't think there's a belt switch in the model so if the belt broke it could be jammed in the motor,try spinning the drum to help it start if that doesn't work unplug the dryer,open the door,remove the two screws that hold the door on and then remove the other two screws on the opposite side,grab the top of the front panel and pull forwards to remove the front panel,you can leave the door on or lift it up and pull out to remove the door,now look to see if the belt broke,if the belt is rapped around the center of the drum then it isn't broke and it will be the motor,that's a good dryer and worth changing the motor on it.

Ld lg3788w gas dryer drum won't turn

not a good model number,most likely you have a broken belt as long as it starts,heats but the drum doesn't spin,if you get a buzzing sound and it doesn't start you could have something stuck in the blower wheel,the motor is jammed or the motor is bad,you can open the door,push the door switch in,spin the drum with your other hand and have someone push the start button,if it starts you have a bad motor.

it could be the extra weight on the motor and the motor is bad,try this,open the door,push the door switch in with one hand and spin the drum with the other hand and have someone push the start button,if it runs and most of the time it does because you're helping it along you need a new more thing,if the filter is in front,remove the duct that the lint filter slides into and spin the drum,if the blower wheel moves with the drum you have a bad motor,if it doesn't you have something stuck in the blower wheel and it jams up the motor because it's attached to the motor shaft.

The dryer is plugged in and the circuts seem to work however the dryer is making a humming noise but it will not turn on fully.

what do you mean it won't fully turn on?do you mean the motor won't run because usually when it humms you either have a bad motor or something is jammed and stopped the motor from spinning.try this,open the door,with one hand hold the door switch in and with the other hand spin the drum,have someone else push the start button while you do this,if it starts the motor is bad,if you can't spin the drum something could be stuck in the blower wheel or the belt broke and could of jammed up the motor but it sounds like you have a bad motor.let me know what you find and next time send the brand name and model number.

When you push the button to start the dryer, all it does is buzz and nothing happens

next time send the model number and brand name,all dryers are not the same!it sounds like a bad the door,push the door switch in with one hand and with the other spin the drum,while you're spinning the drum have someone push the start button,if the motor starts you'll know the motor is bad but it might run for a while before it does this again or it will do it every time but either way the motor should be changed,also on some dryers if the belt broke it will buzz like when the dryer is down but if yours is more like a humming sound like power is going to the motor but it won't run then it's the motor.

Roper rex6634pq0 won't start, buzzes, gets hot on surface

Solution #1 makes no sense as a dryer does not have a water pump!

But the exact same problem happened to my same model dryer. Pull out from wall. Remove lint filter. Take out two screws holding top to lint filter casing. Pry up top at the front (pops out of two plastic retaining dowels and is hinged on the back so you can tip the top up). Remove front panel by taking out two screw-bolts at top of backside of front panel and lift up -- careful to support drum as you do, as the front part of the drum is supported by the flange built into the front panel. Check:

1) Is belt broken (the incredibly skinny belt that runs around the middle of the drum, not the rubber track at the back of the drum). If belt is broke, replace. New belt at internet parts stores is about $10 bucks.

2) If belt is not broke, get down on belly with flashlight and find the spring-loaded wheel that keeps the belt snug against the motor pulley -- push on the spring-loaded wheel and slip the belt off.

Now try to spin the motor pulley by hand. If it turns freely in both directions, it is probably good and the problem might be in the start switch (don't know how to test that).

If the motor pulley does NOT turn -- or is very hard to turn and binds -- the motor is dead. Probably the bearings burnt out (that's what happened to mine after only 4 years of light use). You have to remove the back panel to replace the motor, but it's a simple job if you know what a screwdriver and socket ratchet are for. New motor at internet parts stores is about $80 bucks.

Motor dont run

I am assuming that dryers haven't changed a lot in the way they are made.
First, unplug the appliance for safety. Then remove the filter from the top, and remove the two screws that secure the machine top to the top of the filter slot. Lift the top: this involves a screwdriver wedged under the top 2-inches from the side on each side one then the other. There are clips that secure the top down in those locations. Some pressure on the screwdriver is required to make them release. Lift the top and allow it to rest against the wall behind the unit. There are two 5/16 hex head screws about 2-inched down from the top that secure the front panel to the machine. Removal of those will allow removal of the front, exposing the drum, belt, motor, dust, coins and things that have accumulated. There is a springloaded belt tensioner beneath the drum, it is not hard to reach. Remove the belt, then the drum, to make easy access to the motor. If the motor must be removed, you will need to unplug the connectors joining the wiring harnesses from the top to bottom, and remove the top. There is a fan on the motor shaft, and you will need to remove the back panel and a duct/cover to access the fan. It is possible that the motor is not at fault but something has instead jammed the fan. It wouldn't be the first dead rodent found there, and may not be the last. If there has been a dead smell around the dryer, you might try the fan area first. Re-assembly is mostly just a reverse of disassembly but it can be helpful to have a helper to hold the drum in place with the belt on while you put the front back on.. Hope this is at least helpful for you.

Dryer motor

if the motor buzzes when you push start then it is a bad long as the drum turns freely by hand.
