Maytag STACKED LAUNDRY- GAS dryer not getting hot enough
« on: January 10, 2011, 06:37:27 PM »
Our Maytag dryer, model LSG7806AAE STACKED LAUNDRY- GAS, is taking much too long to dry.  There is heat, but it is noticeably cooler than it should be throughout the entire cycle.  I'm assuming the sensor that regulates the heat needs to be replaced - is this the likely culprit?
Any feedback would be great.
cheers,
Kirk

The fact that you have heat tells me 2 things. Your ignitor is working and your flame sensor is working. The heat comes on at first but then fades. The only thing in the circuit with a histoy of fading out is them coils.
Replace em and party on! part # 279834

So, I changed the coils and still no improvement.  Since doing so I have checked and confirmed continuity with the thermal fuse, the gas cycling thermostat's outer two contacts, the cycling thermostat, as well as the thermal sensor.  At this point I think I've eliminated all potential issues I'm aware of - what am I missing?  Please help!!!!

All that other stuff ok the next thing that makes them type dryers take too long is the blower wheel, part # Y303836
It gets wallowed out and slips making the dryer take twice as long to dry them clothes.

Fortunately, or unfortunately, the fan is working well.  Shouldn't the flame be sustaining longer than the moment the ignitor turns off and goes dark?  could there be something that is preventing the gas valve from remaining on after the ignitor turns off (other than the radiant sensor)?

JW, I was able to maintain the flame when I bypassed the burner thermostat.  Even though it delivers continuity, could it still be defective and cause the gas valve to close too soon?  This is the only thing I have been able to do to get the flame to remain lit so seems to be the issue.  Agree?

  You should replace the thermostat you bypassed, also running the dryer with the covers off will cut off proper air flow and make the flame shut off sooner because it heats the thermostats faster.

Sorry I went up in the woods today but I would try replacing that thermostat.

Take the vent hose off the back and run the dryer one cycle without it. Sounds like a normal response to a restricted  vent from here.

We have heat! 
The burner thermo seems to have been the problem, part # 303395
Thanks much for the help guys.

That is the hi-limit thermo, so we can conclude it failed from numerous over-temp conditions. Bear in mind that this dryer must not be vented using  thin foil. The rest of your vent run in in serious scruitiny at this point. You may not be out of the woods just yet :)

If you'd like to give us a detailed description of how your vent runs thru the house to the outside, we can get a better sense of your dryer's performance expectations.

The venting has definitely been a major issue in the past.  We're in an apt building where the venting runs to the roof - 4 floors straight up.  I am aware of the issues that long of a vertical run creates and in an effort to fix them we recently had an exhaust fan installed on the roof.  This seems to have helped as our drying times did decrease, but fixing the over-taxed hi limit thermo seems to have been the final solution.
Thanks again.

All the apartment buildings I have been in run the dryer vent up to the first ceiling of the laundry room and then to the outside wall between the ceiling of the laundry room and the floor above it.

So if you look at the outside of the building there is a dryer vent coming out the side of the building between each floor. I have never seen one were they run the vent all the way to the roof. Seems that would be the hard way to do it.
