Your dryer was manufactured in June of 1996. If the dryer is not turning on, it could be any of the following:
1. Defective Door Switch. If the door switch is not functioning, this will prevent the dryer from starting. You can check it by toggling the switch at the door. You should be able to see the drum light turning on and off, if the switch is working.
2. Blown Thermal Fuse. The fuse is located on the blower fan housing. To access, you will need to unplug the dryer and remove the back panel. The thermal fuse is a plastic looking component on the blower fan housing on the lower left hand side. It has two wires coming off of it. Disconnect the two wires and measure the fuse with a multimeter. You should read a short (0 ohms) if good. If the fuse is blown, this generally occurs for a reason. The number one cause, is clogged or poorly installed dryer vent ducting. Now may be a good time to inspect your dryer ducting to ensure it is blowing air correctly.
3. Broken Dryer Belt. If the belt is broken, the dryer drum will not turn, but will still attempt to heat. If the belt needs replaced, follow these steps:
a. UNPLUG the dryer and remove the lint screen.
b. Locate the two screws near the lint screen opening and remove. With the two screws removed, the top panel will lift up.
c. Unplug the door switch conector plug and any ground wire that may be installed on the casing.
d. Locate the two screws that hold the front panel in place. There should be one screw on each side in the cabinet interior.
e. With the door shut, lean against the front panel and remove the two screws that hold it in place. Once the screws are removed, grasp the front panel at the top center and lift straight up to remove.
You should now have complete access to the dryer interior. If the belt is broken, this may cause the idler pulley to come loose. This is normal with no tension on the pulley to hold it in place. To install a new belt and re-install the pulley, follow these steps:
a. Loop the drive belt around the dryer drum with the groove side facing the drum. (Try to line the belt up with the wear marks already on the drum from the previous belt).
b. With the tensioner in your left hand, insert the clip end of the idler pulley into the grooves on the dryer bottom casing with the idler wheel pointing to your left. (The grooves are directly in front of the drive motor.)
c. While holding the tensioner in place, insert the belt
UNDER the wheel with your right hand and pull it up and over the drive motor pulley.
If this does not explain it well enough, you can also verify by going to repairclinic.com. Click on the Repair Help link and look for the "Dryer Belt Diagrams" link under the Special Features section on the next page. Look for Whirlpool
and refer to diagram H.
Once you have the belt installed, re-install the dryer front panel by holding it as you did previously. Line up the holes on the inside bottom edge of the front panel with the small mounting cleats on the front edge of the side panels. This can be done by yourself, but an assist may make it easier. Once you have the front panel in place, lean against it to hold it in place and install the mounting screws. NOTE: Don't forget to reconnect the grounding wire and door switch connector plug. Without the door switch connected, the dryer will not run. Lower the top panel back in place and reinstall the two screws.
NOTE: Placing a piece of duct tape over the dryer vent chute will help safeguard against dropping anything down in the blower fan assembly. If you drop any screws down the chute, you will need to remove the dryer back panel to retrieve them.
4. Defective Drive Motor. If the drive motor fails, the drum will not turn. The motors are usually very reliable, but it can happen.
5. Defective Timer. Again, usually a very reliable part.
6. Push-To-Start Switch. If the start button fails, no start voltage is applied to the drive motor. You can take a resistance reading across the terminals with the wires disconnected to see if the switch is toggling properly. You will need to remove the back panel of the operator console to access it.
7. Bad Power Cord. I know you said you had voltage, but WHERE did you measure it? With the dryer unplugged, remove the access panel that covers the terminal block in the back of the dryer. This is where the power cord is installed. Plug the dryer back in and take a reading across the RED and BLACK wires at the terminal block. You should read 220-240VAC. If good, this proves the power cord is good. If bad, unplug the dryer and take the same reading across the two HOT terminals (Left and Right slots) of the wall receptacle. If good at the receptacle, but bad at the terminal block,you have a bad power cord.
