Hair dryer fuse

[Martik]

Heat element burnt out near the terminal so I rerouted and crimped it back
on and bypassed the blown thermal fuse with a 1/2" length of 18 gauge solid
copper soldered to the remains of the fuse leads. There is a bimetal thermal
cut-out in series with the fuse. Is this adequate protection without the
fuse?

No, no, a thousand times no!

The remaining one will be the thermostat. Replace the
thermal fuse with another; they're inexpensive.

Not really, it's best to replace the fuse, though how often does one leave a
hairdryer running unnatended? Personally on my own unit I would probably
just bypass it, but I would never sell or otherwise pass the dryer on to
someone else or recommend that anyone else takes that route.

Gross safety negligence is IRRESPONSIBLE!!!
You can bet the farm that if there was any way to make the device safe
without the thermal fuse, it wouldn't be in there.

It's really easy to assume that you can control all the variables. YOU
CAN'T!!
What if your kid borrows it? Somebody buys it at a garage sale. Just
because you didn't intend it doesn't mean it won't happen.

I was burned out of my appartment by the idiot next door who did
something stupid. I expect he was sure there was no danger to others.

Yes but it's a risk I personally am willing to take, I don't have kids, I
don't often loan stuff out and certainly not a hair dryer. What next, are
you gonna tell me not to burn candles or use my wood stove because they
might burn the house down too? As I said, I wouldn't recommend someone else
bypass safety devices but I've got a lot more important things to worry
about than if someone does it. Now if they were talking about bypassing the
thermal fuse in their central furnace which operates automatically and
unnatended then yes, that would be very stupid.

You will die one day. That hair dryer might still be around. You will
not be capable of giving a damn.

Radio Shack used to sell those.

They have 2 temp ratings 133C or 233C at 15A - which would be suitable? The
only thing I can make sense of on the old fuse is '10A'. I don't think the
amp rating really matters just the temp rating - correct?

If your hair dryer draws 10 Amps you're going to set your head on fire! I'd
use the lowest one - 233 C is hot enough to melt solder.

Ahhh! If only I could dictate the sequence of selection!

Hi...

Just went and looked at one of the girls... 1200 watts,
so 10 amps isn't at all unrealistic. Don't think it's
intended to act as a classic fuse, though - suspect it's
just a current handling maximum.

Anyway, don't tell on me, but I took it apart and looked.
The thermal fuse is in the center of the heating element.
I imagine the greatest concern is that it open if the
fan should stop or slow down.

And for the OP, this one's marked 128.

Take care.

Thanks Ken, I'll get the 133C fuse

Yes. I see some advertised at 1600 W. You could warm a room with that.

With the plastic cases that's essential.

It is very dangerous to bypass the thermo fuse. If there is a burnup, there
will be no protection!

Going from memory, most of these units use a 130 to 150 Deg Cels thermo
fuse. But, it is very important to verify the original, and not use
something that is too far off.

If the thermo fuse is replaced, and it blows again, then there is a
situation where the unit is getting too hot.

In the 1980s I had a Mr. Coffee type maker that the thermal fuse blew
(this was the first time I had seen one of these things) and I wanted
coffee. I cut the fuse out and connected the wires and it worked fine
for about a week. Then one morning I put the coffee on and went two
rooms away to pull in my email as I usually do. After a while I began
to smell something burning. I went back to the kitchen and there on
the counter top was the coffee maker with the tower melted down onto
the base and turning into a molten blob. I unplugged it and when the
mess cooled down I was able to scrape it off the counter top. I found
that the bimetal thermal cut-out had stuck closed and then I knew what
blew the fuse in the first place.

I learned my lesson and never eliminated a thermal fuse again. I'm
glad I had not left for work as I might have lost my house.

Yup. You should see what happens when the body is aluminium. I've seen steam
irons melt and drip on the floor.

Lets put it this way as the commercial states:

Thermal fuse... $1.00
Price of a new hair dryer...... $15.00
Someones Life........ Priceless!

Over the years I have always appreciated and respected your good
technical advice on this newsgroup as I am certain that others also
have found your advice of value;
HOWEVER
I am shocked at your admission that you personally would not bother
with a replacement thermal fuse and would just bypass it. You should
have ended your reply post with your first phrase "it's best to replace
it" .
Even though you indidcated that it would be your PERSONAL course of
action to bypass the thermal fuse, there will be those readers that
have so respected your previous good advice over the years that they
might follow your own personal BAD advice of bypassing an important OEM
safety device like a thermal fuse. I am shocked and surprised that you
would even consider this course of action and bad repair practice;
personal or otherwise. I am sure that I am not the only one who had
this reaction after seeing your BAD ADVICE reply post.

Hi electricitym

We have to give James a break, as I've noticed he's
been very helpful, and hopefully will be for a long time
to come.

We're allowed to disagree from time to time, and I'm
sure that since I'm getting old, stroke-damaged, and
forgetful, sooner or later you're all going to disagree
with me

Besides all that, one of the major advantages to
news groups is that one question is almost certain
to be answered by many; so you get second and third
and twentieth opinions.

Take care.

Ken
