Re: dryer has no heat to it, but runs
Running is good. That means lots of stuff is working. On the motor is a switch that turns the heat on once the motor gets up to speed. The other wires on the motor are start and power for run. Check your heater elements for continuity. Running usually means the door switch is ok, timer ok. Check around for fuses, burnt wires, loose wires. Check the heat sensors for continuity. They should conduct electricity untit they get hot.

it sounds like the control board is going bad but i wouldn't buy any parts for this dryer,soon you won't be able to get parts for it,put the money into a new dryer not to mention that the neptune products is what took maytag out and now whirlpool owns maytag.you could also have a problem with one of the connections or a bad wire in one of the connections and when you move the wires it's working again and this could be from the heat,after years the wires get brittle,you could buy the new board,put it in and if it's a wire you're back to square one,but from what you say it's either a wire in one of the connections or the board.good luck with your dryer.
1Turn off and unplug the dryer. Since you need to remove the front panels and expose the electrical wiring of the dryer's buzzer you should turn the dryer off and then unplug the machine to avoid shocks. Once the dryer has been unplugged, turn its dial to the "on" setting to make sure the dryer is completely powered down. 2Locate the buzzer. The best way to locate the dryer's buzzer is to check the machine's schematic or manual. The buzzer is usually located behind the front panel of the machine. In some cases the buzzer is located behind the dryer's back panel. Dryer buzzers are generally small black boxes that are wired to the timing device.
Open the front panel, remove heat exchanger and clean. also clean out lint tray.
this might help a little. Now lets check if the thermal sensor or heating element needs to be replaced.
Unplug the dryer. remove the panel in the back of the dryer that covers the heating element. ( the inner panel). On top of the heating element you will see a thermal sensor with a small red button on it. Thats the manual reset button. To test if the heating element is working properly you can disconnect the wires from the sensor and clip the connectors together . Plug the dryer back in and start it. pay attention to the heating element. It should begin to glow shortly. if it doesn't then your heating element is bad and needs to be replaced.
Unplug the dryer. Connect the wires back to the thermal sensor. Plug the dryer back in. Before you start the dryer, press the red button on the thermal sensor. Start the dryer. If the heating element doesn't come on and dryer doesn't heat, then you need to replace that sensor.
more then likely it may be your thermal fuse, which is located on the backside of the dryer, unplug the dryer and to test you can bypass the fuse by taping the wires together and running the dryer, and running it for about one minute. You should have heat, as this is a safety feature and if it senses to much heat it will blow, meaning that the vent is restricted so when you go to replace fuse you will need to clean the venting system. Good Luck Tim
First ck and make sure you have 220 volts to the dryer. It will run on 110v if one side of the breaker is bad. The other culprits are a limit switch heating element or thermal fuse. If you have 220 volts and the dryer runs just does not heat first turn off the power to the dryer and unplug the dryer from the outlet. Pull the dryer out and remove the lower back panel it is held on by several 5/16 hex screws. (not the back plate on the switch panel) Remove the back and your heater is on the lower right hand side and is inside an metal shell. The thermal limit is also on the metal shell and will have several wires running to it. And if you trace the wires from the element and this thermal limit it will go to the thermal fuse it is on the lower back slightly to the right of the dryer and has two wires run to it and is about the size of a dime or smaller. Unplug the two wires from the termal fuse and hook them together with a papper clip or just tape them together make sure it doesn't touch metal. (this will short it out) and then plug up the dryer and try it to see if it heats you do not need to hook up the vent. (make sure not to touch the back of the dryer and especially any exsposed wires. If it heats up your thermal fuse is bad replace it. If it does not you should check your heating element first unplug the dryer and reattach the wires to the thermal fuse. Then the heating element metal shell should be removed. First unplug the wires to the heating element and thermal limit switch and mark them so you know where they go. Next remove the screw at the top of the metal shell pickup and pull back on the shell to disengage it from the dryer. You can then remove it and inside is the heating element it is attached to the shell with 5/16 hex screws. Remove the screws and pull the heating element out of the bottom of the metal shell. Look closely and you should see the heating element break. The element is a coiled wire and when it heats up the wire actually grows in length and when it is off it cools and shrinks this causes fatique and the wire breaks over time. If the wire is broke replace the element. Look very closely use a pencil to move the wire slightly it is sometimes very hard to see the break. If broken replace the element and make sure not to touch the new element with your fingers this can case premature hot spots which causes the element to fail prematurely. If the wire is not broken then the thermal limit attached to the metal shell that holds the heating element is bad. Before doing any of the above you should look at all the wires in the back of the dryer and look for burnt or broken wires replace or repair them and check the dryer before any other repairs should be entertained. Before replaceing the back on the dryer clean all of the lint out of the back of the dryer and out of the dryer vent. This is very good insureance for the future of your dryer. Good Luck and I hope this is useful.
check the upper and lower limit switches on the heating duct. they act like fuses and and pop if the go bad. to check. first unplug dryer then remove back panel. the heat tube should be on the right and have two disc looking things with two wires going to them. check top one first. pull wires off and withjumper wire connect the two wires together. now plug dryer in and check to see if it heats. if not check the lower one. do not run dryer for longer then i takes to see if coils heat up. if still no heat then u need to pull heating element off and check for an open in the coil.
It could be a circuit breaker, fuse, or electrical problem. Just because the motor runs doesnt mean it will heat.
You should check for power first.
Then unplug the dryer remove the lower front panel, two screws.
Mark and label any wire you remove so you know where they go!
in the back on the left is the heating element, check for burnt wires, take the element out and check for a broken wire on the back side also check all the thermostats, and electrical components to make sure they are good.
