Based on the information provided above, I am unable to provide a positive solution to your issue. Your model number is incomplete! I have provided some common solutions to help guide you in your search. This information is for a non-specific brand model, gas dryer.

It normally takes about 45 minutes for a dryer to dry a full load. If your dryer is taking more than an hour, check these:

Vent
Flame sensor/gas valve
Internal ductwork
Cycling thermostat
Lint Filter Vent: Frequently there's an obstruction in the vent duct from the dryer to the outside of the house. For the dryer to heat properly, the duct must be clean and clear of lint or any other substance. Also note that, to maximize drying efficiency, the vent should be as short as possible.

Flame sensor or gas valve coils: This is the most likely cause. Click links below. http://www.repairclinic.com/SmartSearch/SSPartDetail.aspx?PartID=3449&PPStack=1 http://www.repairclinic.com/SmartSearch/SSPartDetail.aspx?PartID=3229&PPStack=1 There's a flame sensor near the igniter. If it's defective, the gas may shut off prematurely. Another common problem occurs when one of the electrical coils on the gas valve fails intermittently. If this happens, the flame shuts off before the thermostat sends a signal, which can greatly prolong the drying time. If the sensor or the coils are causing the flame to shut off, replace them.

Internal ductwork Your dryer has some internal ductwork. If it gets clogged, your dryer can't dry properly. In most dryers, to get to the internal ductwork to clear the clog, you have to substantially disassemble the dryer. A quick way to check for internal clogs is to remove the lint filter and use a flashlight to inspect the inside of the duct. If it looks clogged and you can't clear it using your vacuum, contact a qualified appliance repair technician.

Cycling thermostat Although this isn't a common problem, one of the thermostats that controls the temperature in your dryer may break and cause the dryer to heat poorly. If so, you need to replace it. The thermostat is usually a small, round, black device mounted to an oblong steel plate. The plate is mounted to the internal ductwork with two screws.

at the bottom of the front panel you have two screws, remove those and swing out at bottom and drop off

SOURCE: dryer wont start when start button is pressed, but humming sound

I'd sure start by making sure the belt isn't broken. You can usually see the belt with a flashlight after accessing the panel (some are in front, others in the rear) - don't go probing around bare armed without unplugging the unit....
