I have a Kenmore Dryer Mod: 110.60612990 Ser: MK2251018.
My girlfriend is saying it is wrecking and shrinking her clothes.
The temp is way to hot.
She has it set to the Knit/Delicate Low Heat cycle and it is coming out too hot.
I don't know anything about laundry. I'm a guy! I throw the clothes in and push the button! However, there are times when I think it is too hot also.
I have tools and can troubleshoot and repair, but I need some direction.
I have the owner's manual, but that is of no help. I looked at the full diagrams on the Sears site and it shows two thermostats. Is there anyway to test these? Or do I have to just replace?
Tell me what you can.
I appreciate the input.
Thanks, Bob

Before you replace anything take off the back, and take off the top (by taking out the two screws that hold it to the cabinet. They are accessed by removing the lint filter) and clean everything out. Be sure to take off the lint chute and clean it out. Check the blower wheel to make sure it is operational. Clean the vent pipe that goes to the outside. Finally examine the heating element to make certain it is not grounded to the frame in some way.
The major reason why a dryer runs too hot is that the air passages are obstructed.
Anyway, put it back together and check it out again. If you still have a problem you can change out the cycling thermostat and see if that helps.
Good luck.

Thanks for the answer.
I finally got to the dryer.
I cleaned it out completely. Vacuumed and wiped it down.
There really was not build up or blockage anywhere. Just some loose sediment in the bottom.
So, I put the thermometer in the exhaust of the dryer and tested the different settings.
I believe it is running too hot.
My girlfriend is so smart!
My temps are ....
Low = 145*
Normal = 152*
High = 162*
Don't know what the recommended temps are for this dryer, but based on temps I have seen on various sites, I am high.
What should I do now?
Replace them all, or one at a time.
There are 3 therms on this unit.
Thanks again for the help.
Bob

OK. I'll do it.
In a nut shell, what does the cycling thermostat do?
There are also two other thermostats.
I'll have to try and find a description of them all.
If you know where a description lives, please point me to it.
Thanks ...

The cycling thermostat does just what it says it does, it maintains a constant temperature by cycling the heating element on and off as the dryer heats up. It measures heat from the exhaust air, and when the air gets to a certain temperature it shuts off power to the heating element, which causes the air temp to go down, which causes the cycling thermostat to turn the heating element back on. Your house thermostat, operates the same way.
Your cycling thermostat also has a little heater in it. When you set the dryer on lower temps the heater in the thermostat heats it up so it thinks the temp is higher than it really is, which causes it to shut off current to the heating element sooner than it otherwise would, resulting in lower drying temps.
So you can see why a failure of this part is likely to be your problem.
Your model is somewhat unusual in that it only has two other thermostat like items, so I don't know a site that would explain things without being confusing. The one next to the cycling thermostat is a thermal fuse. If the dryer gets too hot it blows and interrupts current to operate the machine. This keeps your dryer from burning down your house, which is a good thing. This fuse is a one time item,if it blows it must be replaced. The other device you have is a thermal cut off and is similar item but it is mounted on the heater housing. If the heater housing gets to hot it shuts things down.It is probably a good idea to replace this one for extra safety.

I guess there are only two thermostats. One by the element. One by the exhaust. Which is the cycling thermostat?
By the exhaust? Or element?
I've ordered the part. I'll figure it out when I get it.
What is the part number of the other thermostat in case I need to order it also.
Thanks ...

Sorry, sidfink43.
I jumped the gun. I did not see your response.
I need to look before I leap!
Anyway, I'll wait until I get the part and go from there.
The dryer works, so I guess it is not the thermal fuse.
I'll replace both of the thermostats if you get me the other part number.
Thanks

Both thermostats have been ordered.
I'll probably replace them next weekend.
I'll let you know how it went.
Thanks again for your help.
