Thermal Fuse
The thermal fuse helps to prevent a dryer
fire by shutting off power to the dryer if it overheats. If the dryer
won't start check this fuse first. Test the thermal fuse with an ohm
meter or continuity checker. This is the most common part to fail when
the dryer won't start. Once the thermal fuse has blown, it has to be
replaced. It can not be reset.

Start Switch
The start switch is on the dryer control
panel. Depending on the model, either press a button or turn a dial to
start the dryer. If the start switch fails the dryer won't start or make
any noise. Test the switch with an ohm meter or continuity checker. If
the dryer hums when the start switch is activated, or if the motor runs
only while activating the start switch, the motor might be defective or
something might be binding the drum preventing it from turning freely.
If the dryer start switch does not have continuity when it is activated,
it will need to be replaced.

Door Switch
The door switch is located near the dryer
door and is activated when the door is closed. If the door switch fails,
the dryer won't start at all. Most door switches will make an audible
click when they are activated. If the door switch makes a clicking sound
when activated it is probably not defective. If it doesn't make a
click, it can be checked with an ohm meter or continuity checker. The
door switch is relatively easy to replace and is usually not very
expensive.

Drive Motor
On most dryers the drive motor turns the drum
and the blower wheel to exhaust the air. If the dryer won't start the
motor might be defective. Before replacing the motor, check the thermal
fuse, start switch and door switch because all three are more likely the
cause. If the dryer won't start and the dryer motor makes a humming
noise there might be something caught in the blower wheel, or the drum
might be binding. Try removing the belt from the motor and checking the
blower wheel for obstructions. The dryer motor can't be tested easily.
If the more common components have been checked and it seems the motor
itself is defective, it will need to be replaced. It is not serviceable.

Drive Belt
On most dryers, if the drive belt breaks the
motor can still be heard and it will still be blowing air out the
exhaust tube, but the drum will not spin. However, in some dryers when
the drive belt breaks the tension pulley arm trips a switch which shuts
off power to the entire dryer. If the dryer won't start, check to see if
the belt is broken. If it is, replace the belt and the dryer should be
fine. If the belt is not broken, check the other components that can
fail when the dryer won't start.

Thermal Cut Out Fuse Kit
Most dryers have several temperature control
devices such as a thermal fuse, thermal cut out, high limit fuse or high
limit thermostat. Some manufacturers sell the thermal fuse and thermal
cut out in a kit. These kits normally solve no-heat problems rather than
when the dryer won't start. However, in some models, this kit will
solve both problems. Even though this is not the most common part to
fail if the dryer won't start, both can be checked using an ohm meter or
continuity checker. If they have continuity they are good. If not, they
should be replaced.

Incoming Power Problem
If the dryer won't start, check to make
certain there is electricity to the dryer. For a gas dryer, unplug the
dryer from the wall and plug something else into the outlet to see if
it's working. For an electric dryer, check the home circuit breaker or
fuses. If they are working, check the outlet where the dryer plugs in
with a volt meter. There should be between 208 and 240 volts. If there
is power to the dryer, check the more common items in this
troubleshooting guide.
Belt Switch
If the dryer won't start, there might be a
belt switch that has failed. This is not a common problem and most
dryers do not have this switch. If the dryer has a belt switch, the
switch shuts off power to the entire dryer if the belt breaks. It is
possible that this switch has failed, even if the belt is not broken. It
can be checked with an ohm meter or continuity checker. If the dryer
works at all, even if all it does is hum, this is not the problem.
Main Control Board
The main control board is normally not at
fault when the dryer won't start. First, check all of the other
components in this troubleshooting guide before replacing the main
control board. The main control board can not be tested and must be
replaced if it is defective. If there are obvious signs of burning or a
shorted out component on the board, it should be replaced.
Timer
The timer is normally not at fault when the
dryer won't start. In many situations where timers are replaced they end
up being returned. First, check all of the more common components in
this troubleshooting guide before replacing the timer. If the dryer
won't start, the cause is much more likely to be a thermal fuse or
switch. The timer can not be tested, it must be replaced if it is
defective.
