with millions of replacement parts
available on our website and the help
you need to do the repair yourself if
your electric dryer won't heat here are
the top five most probable causes the
thermal fuse is a safety device designed
to protect the dryer from overheating
the fuse is normally located on the
blower housing although some dryer
models have an additional fuse on the
heating element if the dryer overheats
the fuse will blow and cut off the power
to the heating element you can use a
multimeter to determine if there is a
continuous electrical path present in
the part if not the fuse has blown and
will need to be replaced be aware that
the failure of the thermal fuse is often
caused by the venting system being
clogged with lint to improve air flow we
recommend cleaning out the vent at least
once a year
the heating element warms the air before
it enters the dryer drum if the element
is burned out or any part of the
assembly is defective the dryer will not
heat properly you can use a multimeter
to test the heating element for
continuity if the meter indicates no
continuity then the element will need to
be replaced the high-limit thermostat
located on the heating element monitors
the dryer temperature and will shut the
heating element off if the dryer
overheats the cycling thermostat
normally located on the blower housing
will cycle the heating element on and
off to regulate the air temperature if
either of the thermostats fail the
heating element may not work at all
again you can use a multimeter to test
the thermostats for continuity to
determine if the component has failed or
not to fully operate most electric
dryers require 240 volts of alternating
current running through two legs of
voltage each carrying 120 volts if one
leg of voltage is shut off by a tripped
breaker
or blown fuse the dryer may be able to
run but it won't heat if you suspect the
electrical outlet is not providing
sufficient voltage you can test the
outlet using a voltage meter set two
volts ac
be aware that readings can vary between
210 and 240 volts a defective main
control board can prevent the dryer from
heating as well although this isn't a
common problem while the control board
cannot be easily tested you can inspect
it for signs of burning or a shorted out
component for additional troubleshooting
