Whirlpool Dryer model LER4624BW2 doesn't get hot enough

Sounds like the thermocouple needs replaced. When ever the couple doesn't make enough electricity the gas valve is shut down automatically. Sounds like your thermocouple is right at the threshold of minimum voltage and doesn't generate enough voltage to keep valve open.

If not that try YouTube for some good diagnostic videos:

Did you pull the element out and test it? I think it is your heating element. Visually inspecting is never enough. Just hook it up to high voltage independently to ensure it heats. It will turn red hot.

Hello there and welcome to fixya there are several things that could make this dryer not heat up
Here are the most common things

Thermal Fuse

If the dryer doesn\'t heat, but the drum
turns, check the thermal fuse(s). The thermal fuse protects the dryer
from overheating and helps to prevent fires. If the thermal fuse is
blown, it will have to be replaced.

Gas Valve Solenoid

The gas valve has two or more electric
solenoids which open the valve to let the gas flow into the burner
assembly. If the dryer doesn\'t heat one or more of the solenoids may be
defective. If the igniter glows for 90 seconds but the burner flame
doesn\'t light, replace these coils as a set.


Dryer Igniter


If the dryer doesn\'t heat, the igniter might
be burned out. Check the igniter for continuity with an ohm meter. Dryer
igniters burn out over time, similar to a light bulb.

Heating Element

The heating element on an electric dryer can
burn out over time. If the dryer doesn\'t heat, the element should be
checked for continuity. The heating element cannot be repaired and must
be replaced if defective.

Heating Element Assembly

the heating element assembly on an electric
dryer can burn out over time. If the dryer doesn\'t heat, the element
assembly should be checked for continuity. The heating element assembly
cannot be repaired and must be replaced if defective.

Flame Sensor



Gas dryers have a flame sensor to detect the
heat given off by the flame. If the dryer doesn\'t heat, the flame sensor
might be defective. Check the flame sensor for continuity. This is not
as common as a burned out igniter or thermal fuse.


High Limit Thermostat


Although not common, if the dryer doesn\'t
heat the high limit thermostat can be defective. It can be checked for
continuity. If the thermostat is "open" the dryer doesn\'t heat.


Cycling Thermostat




The cycling thermostat regulates the
temperature of the air in the dryer. If the dryer doesn\'t heat it may be
caused by a defective cycling thermostat. This is not common.


Main Control Board

The main control board is normally not at
fault when the dryer doesn\'t heat. Check all of the other components in
this troubleshooting guide before replacing the main control board. The
main control board cannot be tested easily and must be replaced if it is
defective.


Timer
The timer is normally not at fault if the
dryer doesn\'t heat. In many situations where timers are replaced they
end up being returned. Check all of the more common components in this
troubleshooting guide before replacing the timer

See if you can spin the drum with little resistance or is it really hard to spin?

More than likely a bad timer assembly. They are usually easy enough to replace if you have basic mechanical skills. The part can be ordered from repairclinic.com.

For this job, all your work is going to be behind the machine. Tools you'll need is: 1/4 nut driver or drill with 1/4 adapter and a multimeter with ability to check continuity. With the machine unplugged, remove the back cover of the dryer. Once done, the heating element will be located on the right hand side with two fuses on the housing of the element. Test the element and each fuse seperatly by removing the wires and checking for continuity on each component. All parts should show continuity, so if one doesn't its bad and needs to be replaced
