No...the bulb is probably a symptom of the problem and not the cause. You should start by checking the thermal fuse. These are common symptoms of when a thermal fuse blows. If the model number is correct, you can access the fuse by:
1. UNPLUGGING the dryer and turning the entire unit around so you can access the rear panel (you may have to disconnect the exhaust vent hose).
2. Locate and remove the screws around the perimeter of the rear panel. With the screws removed, the panel will come off. Set aside.
The thermal fuse is located on the blower fan housing on the lower left hand side of the dryer (as viewed from the rear. It is a small plastic (usually white in color) component with two wires attached to it.
Disconnect the two wires from the thermal fuse and take a resistance reading. You should read something close to 0 ohms on the resistance scale if the fuse is good. If the the fuse is bad, you cannot reset it and it must be replaced.
Replacement parts (if required) can be purchased at any of the following websites:
Prices vary between sites, so shop and compare. The first three sites listed also have helpful exploded view parts illustrations to assist you with locating and properly identifying the parts you may need. The thermal fuse is listed as item 23 (part number 3392519) under the "Bulkhead" parts illustration.
If the thermal fuse has blown, it usually blows for a reason. The number one cause, is poor exhaust ventilation or dirty dryer interior, causing the unit to overheat.
Another cause of a dryer that fails to start is a bad power cord, bad receptacle, or tripped circuit breaker.
Double check your power source by unplugging the dryer and verifying the voltage at the wall receptacle. You should read 220-240VAC across the two Hot terminals (left and right slots). If the voltage is incorrect, check to make sure you don't have a breaker tripped. Some homes use 2 separate 120VAC breakers to provide power to the receptacle vice using one 240VAC breaker.
If the voltage IS correct, leave the dryer unplugged and remove the cover plate on 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 voltage reading across the two hot (RED and BLACK) wires at the terminal block. You should read 220-240VAC. If the voltage is good, you have an internal heating problem. If the voltage is bad at the terminal block, but good at the receptacle, you have a bad power cord.
NOTE: If the wires at the terminal block are not color coded, the outer two wires (left and right) are the hot leads. The center conductor is neutral or ground.

If you have any questions, or if your model number differs from the one you listed the question under, please post back and let me know. I hope this helps you.
