Question about Kenmore 63942 Dryer
Want to find the door switch
The door switch is located inside the door on top left or top right of the dryer, if it is one of the newer 70 series dryer it will be on the inside bottom towards the middle

The following link explains how to diagnose a dryer "no heat" problem:
If you require addtional assistance, please let me know. I hope this helps you diagnose your problem.

most of the time it is the door switch that goes bad,also you can check the main fuse inside the dryer on the blower box,and always make sure your dryer vent and wall vent are clear to vent,let me know what you find-mike

check the thermal fuse if it is blown also change the high limit thermal cut-off fuse www.repairclinic.com shows your parts. go there and enter model number. Also check the heat element. to get into it remove the lint filter and the two screws you'll see there then pry the top up at the front corners. And through the back you should find the heat element and blower housing and thermal fuse and high limit fuse and cycling thermostat.

Easy fix. I had the same problem on mine. You need access to the back. Remove back cover. Look at bottom left, you will see two blue wires going to a white plastic item next to one of the thermal sensors. This white plastic piece is a fuse, or fusible link if you like. I'm not sure what the rating is, but you can take the old one to a parts store. They can match it. Now, why did it blow? Well, if the dryer is old, it could be just worn out. But more than likely, one of your 230 volt lines has degraded due to a bad connection, thus drawing more amps, thus blowing the fuse. Look at where the power cord comes in at. Is there any discoloration or oxidation at the terminals? If so, replace the power cord at this time, and try to clean up the terminals as best you can. Also, at this time, you probably better take a look at the lint collector duct running along the left side down the back. It's probably so clogged with lint that your dryer does't dry as fast anymore, and air flow from the exhaust is restricted. Take the duct off and clean it out, or blow it out with compressed air. You should be up and running now. Have fun...

DOOR LKS fuse
Driver door lock actuator
Driver door lock switch
GMLAN serial data link
Keyless entry transmitter
Passenger door lock actuator
Passenger door lock switch
Remote control door lock receiver (RCDLR)
The DR LCK fuse supplies battery voltage to the body control module (BCM) for the power door lock system. The BCM supplies and monitors a reference voltage to the driver and passenger door lock switches through the door lock switch lock/unlock signal circuit. Each door lock switch receives ground at G300 which is also the ground for the door lock and unlock relays located in the BCM. When a door lock switch is placed in the lock position, the reference voltage is switched to ground and the BCM senses 0.0 volts on the door lock/unlock signal circuit. When a door lock switch is placed in the unlock position, the reference voltage is switched to ground through a 1.5k ohm resistor that is internal to each of the door lock switches and the BCM senses approximately 2.9 volts on the door lock/unlock signal circuit. The BCM interprets what position the activated door lock switch was placed in based on the voltage drop.
The BCM, upon receipt of a lock or unlock switch signal, will switch the appropriate door lock/unlock relay coil control circuit to ground causing the appropriate door lock/unlock relay to energize. With the relay energized, voltage is applied to the door lock actuator control circuit causing the door to either lock, or unlock depending on what command was received from the power door lock switch or remote control door lock receiver (RCDLR). When a power door lock/unlock relay is not energized, the switch contacts are normally grounded through the BCM which provides ground to the appropriate door lock actuator for the lock/unlock function being performed. The power door lock/unlock functions are performed by reversing the flow of voltage through the door lock actuator control circuits. The BCM has three internal drivers for the power door lock system. Driver door unlock, passenger door unlock and all door lock. This is done to isolate the driver door lock actuator so it can be unlocked separately from the passenger door. For additional information concerning keyless entry, refer to Keyless Entry System Description and Operation.
This is one you may want to take to dealer or some other ASE certified repair shop ! To do this right you need a Tech 2 scan tool !
Ignition ON, observe the scan tool Door Lock Switch parameter while using the driver and passenger door lock switches. The parameter should change from Idle to Lock and Unlock.
If the value does not change, refer to Door Lock Switch Malfunction.
Command the doors to LOCK and UNLOCK with the scan tool, the door lock actuators should LOCK and UNLOCK when changing between the commanded states.
If one or more doors do not LOCK or UNLOCK, refer to Door Lock Malfunction.
