Everything works but the heat will not come on nor do I see the ignitor attempting to ignite ie a glow. I do hear the normal click when I turn it on but no heat. I took off the cover and pushed the button to start it and I dont see any attempt to ignite. Is this the coil pack or the ignigtor? I also tried the suggestion of fusing together the theromal wires and that did not work either.

Re: mdg3000aww no heat
Ignitor. Replace it since you are getting no glow this will solve your problem all together. Ignitors can have small cracks and if you cannot see them until you take it out. If I have helped please rate

Normally a dryer will come on and then go out due to insufficient air flow. I your case, you say the igniter never comes on. This tells me that the thermistor is probably OPEN. With a cold dryer, the thermistor should close the contact and allow the relay to pull in. If you have poor air flow, the thermistor will heat and then break the circuit and stop the igniter from working.
mounted on top of the gas vavlve is black electrical coils when energized it opens the gas valve,if one of the coils are defective it wont open and let the gas thru,its hard to test the coils so most repairmen just replace them all
If this is a gas dryer it may be the ignitor has failed. There should be a panel you can remove to inspect the burner compartment. Turn on the dryer and look for an orange glow if you don't see any glow the ignitor is probably faulty and should be replaced. If it is an electric dryer it may be a bad heating element. Hope this helps.
While the drum is rotating you should hear the CLICK associated with the gas valve assembly powering up to give out a blast of heat. If ya don't hear no click check the duct fuse. Right next to the control thermostat. If it is blown it kills the circuit to the gas valve assembly. If that fuse is good and the control is also good, then check the flame sensor for continuity, If it is open then the ignitor won't glow. The ignitor must glow and change in resistance then the flame sensor must open up and kill power to the ignitor so that power will be shifted to them coils on the gas valve.

If you are having problems with your gas dryer not heating
the most common problem is that the ignitor goes bad. Even though it glows
sometimes it is still not working properly.
it is either your glow coil or it is your ignitor
open the door and remove the four screws
take the front panel off.
leave the door attached so you can test the dryer
be very careful not to touch any wires while you are doing this
now close the door and turn the dryer on
does the ignitor turn on?
if yes that is good
does the ignitor glow and no flame?
sometimes it will take a minute to show it's problem
if the ignitor glows and no flame replace your ignitor coils
make sure to turn the power off when replaceing the coils
First make sure that the gas valve is on. Then verify that the gas connector is not kinked or restricted. then remove the connector at the back of the dryer and make sure there is gas pressure. Then visually inspect the pipe at the back of the dryer. Use a flashlight to inspect inside the pipe and make sure there is no debris inside the pipe that could restrict gas flow. On this dryer there is no removable burner door cover on the front or inspection window so you will need to remove the back panel of the dryer. Once the panel is removed you can turn on the dryer. You should first hear a click sound. That is the first gas solenoid valve opening. Then the igniter should start to glow. Once the igniter reaches 2200 degrees the secondary gas solenoid valve should click and the burner will come on. If you do not hear a click when the dryer is first turned on you will need test the first gas solenoid valve. Make sure it is getting voltage with a fluke meter. You can also touch a piece of metal to the top of the valve and the top should be magnetized when active. If you hear the first click but no igniter glow then verify the igniter is getting voltage and test the igniter with a fluke meter. You will need to test the ohms and most should be 500 to 700 ohms. If the igniter does not get a good reading or none it is probably defective and needs replacement. Usually most places that sell appliance parts will test the igniter for free. Just because the igniter glows does not mean that it is good. It can glow but not reach the 2200 degrees needed for the proper operation. Now if the igniter is good and you hear a second click then there might be a restriction somewhere in the gas line between the solenoids or the gas orfice at the burner. The sensor Gort was talking about is the flame rectification sensor and can detect the flame. It is rare for this to be faulty but not impossible. If you get flame for a couple seconds and then it shuts off it could be this sensor. Blow the burner assembly and this area off with compressed air and lint can block the sensor's ability to detect the burner flame. Also I believe your dryer has a larger fan blower than standard dryers. If this blower motor is not working the rest of the system will not come on. make sure the assist fan is working and that the vacuum switch is working and not stuck. Also check the vacuum line is not disconnected or restricted. And always remember that there are exposed power connections inside the dryer that could shock you and cause injury. use caution and if you do not feel comfortable working on this you might want to call a professional.
It sounds as simple as the glosil/igniter went bad or the high limit thermostat are not working at all.
Check your high limit on top of the burner for contuinity first.
If that unit is fine then locate the gas unit and check to see if you igniter is working - if it isn't getting red just go ahead and replace it.
That should solve the problem.
