Speed Queen dryer still overheating
Robert Hancock
We have a Speed Queen model BE 1060 electric clothes dryer that is
overheating. The top is uncomfortably hot to the touch and the safety
thermostat is clicking off. The dial will not advance properly on the
automatic cycle. The operating thermostat was replaced but was no help. The
outside vent appears clear, and when I take the vent hose (only about 10-12
feet long), hold it vertically, and shake and beat it, nothing significant
comes out. The blast of air from the outside vent seems quite strong. I
checked for heater ground shorts - there is no continuity from the heater to
the casing. Is it possible it's shorting when it's heated up but not when
it's cool? I didn't see anyplace where the coils might be touching anything.
I vacuumed out all the lint I could find in the dryer, and the blower
assembly seems clear. Is there anything else which could be causing this
problem? Is it possible there's some stubborn lint in the hose that I can't
see that's blocking it or something? I really can't think of anything else
and this is starting to annoy me! Any help would be appreciated.

Hi, Robert
Most electrical driers I'm familiar with have simple snap-action
thermostatic switches, in the discharge path. Sounds like the one you're
using with your mode-switch setting is stuck closed. And maybe your
humidity sensor is stuck, too.
If you know what you're doing, you can check at the rear of the drier, find
the stuck switch/sendsor, and replace it for a few bucks. Betcha.
If looking at the wiring diagram and manual doesn't make sense, don't fry
yourself.

But I already replaced the operating thermostat, and there is no humidity
sensor.

If you are running the dryer without the front panel in place (for testing
purposes) the saftey thermostat will trip, the dryer top will get hot, and the
automatic cycle will not advance.
Run the dryer without the vent connected for a load or so to see if the problem
persists.
It is hard to judge the air flow outside without something to compare it with.
So make sure the vent hose is clean. Take it outside and wash it out with your
garden hose. This will clean it like new. Cut off any excess length which
could cause problems.
Make sure the vent hose is not kinked or collapsed when you push the dryer back
in place.
Some soft vinyl hoses will hang almost straight down from your vent hood pipe
without forming a bend. The bottom edge of the pipe cuts off the flow.
Install a metal elbow if this is a problem. Check the vent hood itself for
clogging or stuck flap.
Make sure the blower wheel is tight on the motor shaft. Is the inside of the
squirrel cage fan clean?
Make sure the door latch pulls the door in tight. Is the gasket missing.
Are the drum seals, front and back, worn? On a SQ you will usually find small
felt rectangles on the dryer floor.
Are the air inlet holes in the back of the drum open? The ones in the door?
The lint filter duct?
Hope this helps, Len

I determined that the top latch that holds the door shut is partially
broken. I tested how much leakage around the door there was. If you put a
plastic bag over the door you can see it getting slightly sucked on around
the edges. Would that be enough to cause this problem? I plan to get a new
latch anyway as they are cheap, just wondering.
