The exhaust path is completely clear. 

What components would be causing the device not to heat to a proper level, or perhaps, mis-sense the heat from the coil. 

It does seem like the coil is not providing enough heat...when I moved the thermostat, the coil got red hot, and when the sensor is in place, the coil does not seem to get red at all.  I think it could use to be cranked up a little bit.

You could have an electrical problem or a timer problem. The timer has a contact in it that will get arc damage over time. Sometimes it can be removed and dis asembled and sanded down to make good contact. If the timer is fine and the heating problems persist then the circuit breaker could be faulty. Bad timer contact

Bad circuit breaker

Yeah, ok, I really don't know how to handle this, other than calling in the expensive dudes...

I have confirmed the blower and assembly are working as intended.

Also, the timer looks fine.  No noticeable corrosion or concerns.  This unit is only a few years old, so I am even more stumped about what is going here.

I just don't know what to do.  Again, when I remove the replaced thermostat (move away from the coil) the coil gets HOT, so I deduct this must be a control/sensor issue....

Any last thoughts -- i really have to deal with this, and I'm (almost) at wits end...

I hope you are not trying to run it with the front panel off...it will not heat for long.
The LA1044 element does not glow bright red as long as 450 CFM of air is being drawn over it, just like blowing on a candle. A dryer element should not glow bright red unless there are aiflow issues..most are a subdued red only visble in darkness.  The way to test the thing properly is to seal it back up, remove the vent hose and place a thermometer in the outlet. It must  get to 145 degrees to dry properly. Do this with no clothes in the drum and use Timed dry (60 minutes)

The thermostat which controls the heat during the drying cycle is mounted down on the front of the blower housing.

Right now, I am running the dryer as intended, which takes around 120 minutes to dry a load of laundry.  there is NO way I am going to run this unit without a thermostat properly installed, or somehow modified unless I am sure the unit remains tethered.

i have not yet tried to run the unit without the front panel, and that is not something I feel comfortable trying to do.

As I posted earlier, this unit is struggling to push 100F air out of the back end.  The air flow is good, and the coil seems to be working.  I do not want to throw more money into this thing if it is simply not going to help.

Is there a way to test the 4-wire control (circuit) unit to see if it is working properly?  I am quite familiar with a multimeter, but I suspect testing this unit during operation would be a problem, since it is behind that front cover....

Any ideas?

Them thermostats up by the heater do not control the temp in the drum. They are safetys(limits). You control thermostat(cycling thermostat) is as pictured by Mr Campbell. Mounted on the blower housing.

If I replace the cycle thermostat controller, and it doesn't fix the problem, what else could be the issue?

I'll tell you, I do not envy you guys and fixing this stuff for a living!

I'd say you have a voltage issue. Check for 240 volts with the meter at the  dryer cord where it attaches to the dryer.

I have seen a few where the limit thermostat mounting will allow the limit thermostat to SAG so to speak. I usually bend the thermostat up about 3/8 of an inch, away from the element. Of course with the POWER OFF. What happens is the heat from the element gets hot right away and trips the limit. I seem to remember Maytag having some type of service bulletin about 10-12 years ago

I have since purchased the thermostat Repair-man pictured.

When removing the previous thermostat, I note it has 240V on it, and the new thermo stat I have purchased (and the one pictured) is labelled 120V.

I am hesitant to supply power to this unit without verifying nothing bad will happen.

Any input?
