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

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
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.
I've got an easy way for you to check, and then we can help you from there. First pop open both lids to your furnace (this may require a screwdriver). Turn up your thermostat, push the safety interlock button in if it has one (it's a button that turns off the power when the doors are removed), and watch.
On most modern furnaces (past 20-25 years) you'll hear/see: 1. Inducer fan 2. orange glow (ignitor) 3. Gas valve opening and ignition (flames) 4. Main Fan.
that's normal heater operation. The most common issue here is a burned out ignitor, in which case you wouldn't see the orange glow but the sequence would attempt to continue anyway (the gas valve will open and hiss gas, but it won't lite, then it'll give up and try again a few minutes later).
On older furnaces there's a pilot light to start with, the click of the gas valve and boom... ignition.
On new furnaces it's Inducer fan gas valve opening spark - ignition Main fan.
and there are some oddballs in between, particularly the Lennox Pulse. If that's your furnace just back away slowly and call a professional... some guys won't even touch those, so be sure to mention what it is... if you call a pro.
So go ahead and watch it run, then tell me/us what you see.
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
