Kenmore dryer that shuts off prematurely

Hi there,

I have a Kenmore dryer (model #110.72982101) that shuts off prematurely while drying. It is an intermittent problem where sometimes it will dry a complete load without stopping, but mostly it stops at some point during the cycle - sometimes having to restart it 5 times during 1 load. It doesn't seem to matter if it's on the timed cycle or "moisture sensor" cycle. After it shuts off, I have to turn the timer knob around in order for it to start back up. I've read that it can sometimes be the motor overheating, but it starts right back up after I mess with the timer knob. I replaced the even heat control board last year when i was having the problem where the dryer won't stay on after pushing the "start" button. I thought that might be the problem again, so I bought another board a month ago and that didn't solve it.

Any ideas?

Thanks,
Ryan

rsmitty, Welcome to the DIY Forums.
Sometimes the problem is as simple as checking the exhaust duct. You may have lint building up in the duct and even in the back of the dryer at the exhaust hole. When the dryer gets at a certain temp, it says "Clothes are dry". Then shuts off. It comes back on again because you released the heat when you opened the dryer door. Also check to see (if you have a flapper type cover outside) if the flappers are free to open and not clogged. Good luck.

Thanks. I don't think it's the exhaust. I've also tried running the dryer with the duct disconnected and there's no difference. I also don't open the dryer door when it shuts off. I simply turn the timer knob to "off" and then back to "on" and then it works. Any other ideas?

Thanks,
Ryan

Solenoids, Flame Sensor or Defective Gas Valve

Hello Ryan and Welcome into my Gas Appliances topic.

Three other most likely causes is either the solenoids on top of the gas control valve, the gas valve or the radiant flame sensor on the burner flame hood.

Ohm test the flame sensor with electrical power to dryer turned off or machine unplugged. Ohm meter should show a closed circuit. (Needle swings all the way over to right side of meter.) If circuit closed, sensor is okay.

Solenoids on top of gas valve may be defective. There are two. Any one of them fails both get replaced. Sold and installed in pairs only. Remove them from the top of the gas valve by removing the entire gas valve assembly first.

To accomplish this task, the entire burner and gas valve must be removed. Then the solenoid coils can be removed from the top of the gas valve and replaced.

The gas inlet pipe to the right side of the gas valve has a tiny on/off gas shutoff valve. Turn it off, lever opposite it's current on position. The nut on the gas supply pipe near the gas valve is counter threaded, which means it turns opposite the norm to loosen it.

There will be other sheet metal screws securing the gas valve and burner assembly to the dryers base. Once the entire gas valve is removed, take it and the make, model and serial numbers of the appliance to the local appliance retail parts store.

Remove both solenoids off the gas valve body by removing the hold down cover plate and replace them both if defective. They are sold only in pairs.

Or take the entire gas valve unit to your local appliance parts store and have the entire assembly and all the parts tested individually and as an assembly.

Once at the store, the salesperson can be sure the replacement parts are the correct ones. Replacing the solenoids is simple and the parts come with full instructions inclosed in the packages.

Defective Gas Valve could be the problem. Remove entire unit as an assembly. Take the entire assembly to your local appliance parts store for testing. Gas valves are not repairable.

CAUTION: Do Not attempt to repair the gas valve. This is a non repairable item. Replacement is the only option, if defective.

Retail appliance parts dealers can also help determine what the most likely possible problem may be. They will need the make, model and serial numbers. Appliance parts dealers are an excellent source for original replacement parts and problem resolving matters. Dealers are listed in the phone book under appliances.
