I just moved into a house with an older (maybe 6-7 years old)
washer/dryer set. I was able to do one load of laundry in the dryer,
but since then the dryer trips the breaker every time I use it after
running for maybe 2 minutes. I tried lowering the heat but even at the
lowest heat setting it tripped. I finally set it to "no heat" and was
then able to run it for a full cycle without tripping the breaker.
Any ideas on what the problem could be? Is there something I can do to
determine if it's a problem with the appliance or with the circuit
Try replacing the breaker. Sometimes when the breakers get old, they tend to
trip at a lower current. The internal contacts in the breaker heat up more
because they are warn, and thus the breaker trips.
If the new breaker is also tripping, then you will have to have the dryer
serviced. There may be problems with the heating element, control board, or
the motor. Rather than try to fix that yourself, it will be more reasonable
and safer to have an experienced service person do this type of work.
Thanks, I went ahead an did just that and it seems to have fixed it. I
swapped out the old 30 amp breaker with a new 30 amp breaker from Home
Depot (cost a whole $9!) and was able to run a 10 minute test load of
laundry at full heat without tripping it. I'll give it a more thorough
test later but so far, so good. Thanks to everyone that helped!
We have a dryer ( could be any make! ) that is consistently blowing
fuses ( tripping breaker ) after about 5-10-15-20 minutes. We have
taken the dryer apart to check for clogs in the venting system and to
check if the heating core was okay and they seem to be fine. Any ideas?
Blowing the house fuses/breaker? If yes....the dryer usually will blow
a fuse/breaker right away if there is a problem in the dryer....more
often than not a fuse that blows after the dryer has been running a
while it is a fuse box issue. A test: Put 2 new 30 amp fuses in and run
the dryer with the heat on for 5-10 minutes, turn off the dryer and
quickly remove the fuses from the house fuse box and see if they are
hot at all ( especially on the bottom )....if the fuses are getting hot
they are probably melting the fuse link and not really blowing = fuse
As for most things there are exceptions....a grounded heating element
-may- blow the fuse after the dryer has been on for a while, it is easy
to test for that as well. See link here (
http://www.applianceaid.com/grounded.html ). A burnt/loose power
cord/plug -may- also give this type of a problem.
I'd try another 30 amp breaker before getting too deep into the dryer
Appliance Repair Aid
Check the breaker size and the size circuit required by the dryer.
Don't just up the breaker size without checking the circuit very well to
make sure the wiring is sized to meet the demand per code. If the breaker
is up to size, replace it with the same size breaker, it may just be old.
1) Use a clamp-on ammeter to determine if the dryer truly is drawing the amount
2) Rig up a load resistor drawing "near" the breaker current to test the
or (the cheap & easy test)
3) Change out the breaker. They're inexpensive and trivial to replace.
I'm with Andy here and just want to add that a clamp with a hold feature
would be good. This way if/when it trips you will know without standing
there and staring at it for 20 minutes. If you don't have one you might ask
a friend or neighbor??....Good luck, Ross
Is this an existing dryer that was there when you moved in?
Is it a rental or a purchase?
Check the dryer lint trap and the exhaust duct work.
Look at the cord set and plug--do they show any signs of overheating?
