A1 Pull the dryer out away from the wall. Unhook the vent from the dryer completely. Do not put anything over the dryer exhaust on the back of the dryer. Do a normal load with the vent unhooked. If it dries better or ok like this then the problem is in the dryer venting. Like a blocked vent pipe or a smashed or restricted vent hose.
A2 - If the vent doesn't make a difference, then check the blower wheel for excessive lint build up, check that there isn't anything stuck to the air intake baffle inside the drum, (i.e. the screen on the back wall of the dryer when looking into the drum). Check the lint filter chute for blockage. Check that the heating element isn't shorted to ground. Check the exhaust temperature of the dryer. A meat or pocket thermometer can be used for this. It should cycle between 120 degrees and 170 degrees. Check that the drum seals to make sure the are not worn out.
SOURCE: Clothes won't dry
Check the following to address this issue.
Note: Normal drying time for a dryer
is about 45 minutes (some may take up to an hour).
1. Venting
Make sure the dryer vent hose, as well as the rest of the vent duct,
is not clogged.
Unless regular maintenance is performed, chances are there is a lot
of lint accumulated inside the dryer. This might affect the drying
time and could be a fire hazard. Make sure to have your dryer
cleaned regularly. Because this might involve taking most of the
dryer apart, it is recommended to have a qualified appliance
repairman perform this task.
2. Thermostat
There are a couple of cycling thermostats inside the dryer. If one
of them breaks down, it might affect the dryer's performance.
Replace the defective thermostat.
3. Heating element
A heating element might only be partially burned out, in which case
it would still work but will take longer time to dry the clothes.
Replace the element if found defective.

If your dryer is taking more than an hour, check these. 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. Heating element Your dryer's heating element may be partially burned out. If it is, your dryer still heats, but at such a low temperature that it takes three or four times as long to dry the clothes. If the element is partially burned out, replace it. 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. It overheats Usually when an electric dryer overheats it's because of a defective cycling thermostat or a clogged vent system. Clean any lint from the internal and external ductwork, and/or replace the cycling thermostat (read about cycling thermostats in "Drying is too slow," above). It seems to run forever If your dryer seems to run forever, it could be because of a clogged vent or internal ductwork. Your dryer may have an automatic cycle that turns off the dryer when the clothes are dry. It does this with a special thermostat or moisture-sensing system. Normally, this is what happens during an automatic cycle: The thermostat tells the dryer to heat until the interior of the dryer reaches a pre-set temperature--say 135 degrees. When the dryer reaches the pre-set temperature, the thermostat tells the timer to begin advancing. (If there's a moisture sensor, the timer advances only if the moisture content of the clothing is low enough.) The timer advances until the interior cools, then the thermostat tells the timer to stop advancing, and tells the dryer to start heating again. This cycle continues until the clothes are dry. But?if the vent is clogged, the dryer may never reach the proper operating temperature, so it doesn't send the signal to the timer and the dryer continues to run indefinitely, even if the clothes are completely dry. To fix the problem, clean the vent and/or internal ductwork

First, I assume that the drum spins OK but there is no heat. Many things can cause this. From the most likely cause to the least likely:
1) An open thermal fuse. This is a small "thermostat" with 2 wires at the middle/top of the heater "box" (a tall narrow box on right in the back of the machine), or a plastic type on the duct close to the blower, depending on the model. You will need to remove the back cover of the machine to see these. Check with an ohm meter after disconnecting one of the leads, or jumper the 2 wires together to see if heater works (don't use this way though, fire hazard... replace the device) If this proves to be the cause of the problem, it would be wise to check all ducts and blower for excessive lint buildup. This will reduce air flow, causing overheating and blown thermal fuses.
2) A burned out heating element. Remove tall box on right, element slides out from the bottom together with the "carrier". Look for broken coil, or check 2 terminals at bottom with ohm meter.
3) Burned wires at connectors. Check for obviously overheated wire terminals at all sensors (thermostats and thermal fuses in back), heater box, main terminals where power cord hooks up, etc.
4) Bad thermostats. There are usually 2 or more. A high limit on heater box, just above terminals on the bottom. 1 or 2 will be on the duct next to the blower. Check these with an ohm meter (or continuity checker). Some have 4 terminals, the extra 2 small terminals are small heaters inside the thermostats which alter it's temperature characteristics. These will usually read around 4000 ohms or so. Check the 2 main largest terminals for continuity.
5) Only getting 110 volts: This is often overlooked, but if for some reason one of the poles feeding the 220 power from the house wiring is open but the other is OK (for example, houses with fuses where only one fuse is blown, or a bad circuit breaker with one pole open). The motor and timer run on 110. If the side of the 220 line that feeds the motor is OK but the other one is open the motor will run but the heater, which needs 220 will not heat. Check for 220 volts between the 2 outer terminals where power cord connects or between the 2 "hot" terminals of the 220 outlet the dryer is plugged into.
6) Bad centrifugal switch in motor. This is what actually turns the heater on, for safety reasons, so the heater cannot come on unless the fan is spinning. Otherwise without air flow past it, the heater would burn out.
There are 2 large gauge (usually red or yellow) wires going to the connector on the motor, these go to the contacts inside the motor that turn the heater on.

AF is an error that will flash if a restricted air flow is sensed by the dryer control. If three consecutive cycles have low airflow the control will flash the AF error.
The AF error code can be cleared by pressing the Drying Temp pad for 5 seconds while in stand-by mode. AF will flash in the display for 1 second then "on" will appear in the display. If you press Drying Temp again and "of" will appear in the display indicating the AF error display has been turned off. Try this procedure and see if the "of" error goes away. If the "of" came up in the display by itself then the keypad may be stuck. However After cleaning the dryer's lint screen, ensure that the exterior exhaust hood connected to the dryer is unblocked, ensure that the vent connecting the dryer to the wall is clear and see that the vent is cleaned professionally.

AF means Air Flow. Check the Fan.
