The sensing light is on...the dryer won't run. I've tried unplugging the machine, checking the fuse, making certain the door is shut firmly and pushed the start button firmly 5-10 sec. Nothing. Help

The error message you are seeing on your Kenmore Elite HE3 dryer could be caused by a few different things. Here are some troubleshooting steps you can try:

1. Check the power supply: Make sure the dryer is properly plugged in and that the circuit breaker or fuse is not tripped or blown.
2. Check the door switch: If the door switch is faulty, the dryer may not start. Check that the door switch is engaging properly when the door is closed.
3. Check the thermal fuse: The thermal fuse is a safety feature that can cause the dryer to not start if it is blown. Check the thermal fuse for continuity with a multimeter.
4. Check the belt switch: If the belt switch is faulty, the dryer may not start. Check that the belt switch is engaging properly when the belt is in place.
5. Check the moisture sensor bars: The moisture sensor bars can become coated with fabric softener residue, causing the dryer to stop mid-cycle. Clean the bars with rubbing alcohol and a clean cloth.
6. Check the control board: If none of the above steps work, the control board may be faulty and need to be replaced.

If you are unsure how to perform any of these steps, it may be best to contact a professional appliance repair technician.

Try cleaning the sensor strips inside the drum. Sometimes they get gummed up. Check the exhaust vent and make sure it is clean and clear of obstructions

If the washer is receiving power but doesn't start, the switch that senses whether the lid or door is locked might have failed.So check the following steps:
1)Open the door then confirm the door firmly shut.
2)Select the cycle
3) hold Start for 1 second.
If still it is not starting then follow the link below

Timer The timer is normally not at fault when the dryer won't start. In many situations where timers are replaced they end up being returned. First, check all of the more common components in this troubleshooting guide before replacing the timer. If the dryer won't start, the cause is much more likely to be a thermal fuse or switch. The timer can not be tested, it must be replaced if it is defective.
Main Control Board The main control board is normally not at fault when the dryer won't start. First, check all of the other components in this troubleshooting guide before replacing the main control board. The main control board can not be tested and must be replaced if it is defective. If there are obvious signs of burning or a shorted out component on the board, it should be replaced.

Belt Switch If the dryer won't start, there might be a belt switch that has failed. This is not a common problem and most dryers do not have this switch. If the dryer has a belt switch, the switch shuts off power to the entire dryer if the belt breaks. It is possible that this switch has failed, even if the belt is not broken. It can be checked with an ohm meter or continuity checker. If the dryer works at all, even if all it does is hum, this is not the problem.

Incoming Power Problem If the dryer won't start, check to certain there is electricity to the dryer. For a gas dryer, unplug the dryer from the wall and plug something else into the outlet to see if it's working. For an electric dryer, check the home circuit breaker or fuses. If they are working, check the outlet where the dryer plugs in with a volt meter. There should be between 208 and 240 volts. If there is power to the dryer, check the more common items in this troubleshooting guide.

Thermal Cut Out Fuse Kit Most dryers have several temperature control devices such as a thermal fuse, thermal cut out, high limit fuse or high limit thermostat. Some manufacturers sell the thermal fuse and thermal cut out in a kit. These kits normally solve no-heat problems rather than when the dryer won't start. However, in some models, this kit will solve both problems. Even though this is not the most common part to fail if the dryer won't start, both can be checked using an ohm meter or continuity checker. If they have continuity they are good. If not, they should be replaced.

Drive Belt On most dryers, if the drive belt breaks the motor can still be heard and it will still be blowing air out the exhaust tube, but the drum will not spin. However, in some dryers when the drive belt breaks the tension pulley arm trips a switch which shuts off power to the entire dryer. If the dryer won't start, check to see if the belt is broken. If it is, replace the belt and the dryer should be fine. If the belt is not broken, check the other components that can fail when the dryer won't start.

Drive Motor The dryer drive motor turns the drum and the blower wheel to exhaust the air. If the dryer won't start the motor might be defective. Before replacing the motor, check the thermal fuse, start switch and door switch because all three are more likely the cause. If the dryer won't start and the dryer motor makes a humming noise there might be something caught in the blower wheel, or the drum might be binding. Try removing the belt from the motor and checking the blower wheel for obstructions. The dryer motor can't be tested easily. If the more common components have been checked and it seems the motor itself is defective, it will need to be replaced. It is not serviceable.

Door Switch The door switch is located near the dryer door and is activated when the door is closed. If the door switch fails, the dryer won't start at all. Many types of door switch will make an audible click when they are activated. If the door switch makes a clicking sound when activated it is probably not defective. If it doesn't make a click, it can be checked with an ohm meter or continuity checker. The door switch is relatively easy to replace and is usually not very expensive.

Start Switch The start switch is on the dryer control panel. Depending on the model, either press a button or turn a dial to start the dryer. If the start switch fails the dryer won't start or make any noise. Test the switch with an ohm meter or continuity checker. If the dryer hums when the start switch is activated, or if the motor runs only while activating the start switch, the motor might be defective or something might be binding the drum preventing it from turning freely. If the dryer start switch does not have continuity when it is activated, it will need to be replaced.
Thermal Fuse The thermal fuse helps to prevent a dryer fire by shutting off power to the dryer if it overheats. If the dryer won't start check this fuse first. Test the thermal fuse with an ohm meter or continuity checker. This is the most common part to fail when the dryer won't start. Once the thermal fuse has blown, it has to be replaced. It can not be reset.

Several different problems could prevent your dryer from running. Make sure that the door is firmly closed and hold down the start button for a couple of seconds to start the dryer. If you hear a click from the control board then the door switch and the control board are likely okay. You could have a blown thermal fuse or a broken belt in the dryer. To check these components,unplug the dryer and remove the bottom front service panel as shown in the first image below. With this panel removed, you can tell whether the drive belt is broken. If the drive belt is okay, I recommend checking the thermal fuse. This fuse is located on the blower housing as shown in the second image below. It will have light blue wires attached. To test the fuse, remove one wire and measure the resistance across the leads of the fuse with a volt/ohm meter. You should measure near zero ohms of resistance (continuity). If you measure infinite resistance, then the fuse is blown and will need to be replaced. You can verify that this is your failure by taping the contacts of the light blue wires together with electrical tape to "bypass" the thermal fuse. Reassemble the dryer and see if the motor runs with this fuse bypassed. If it does, then this verifies that the blown thermal fuse prevented the dryer from running and that this was the only failure. NOTE: Do not continue to run the dryer beyond this brief test with the thermal fuse bypassed. This component must be replaced. It is an important safety feature of the dryer.

You can order a new thermal fuse from the Sears PartsDirect website. The part number is 3392519.

must be the thermal limit on the blower housing I believe acess is from the back unplug take off back acess and look for a small white thernal limit (plastic fuse) on the blower housing. take it to a dealer to check or ohm it out it should have continuity

Check the following:
Is the power cord plugged in?
Has a fuse blown, or has circuit break er tripped?
Was a regular fuse used? Use a time-delay fuse.
Is the dryer door firmly closed?
Was the START button firmly pressed?
Is a cycle selected?
