Hair dryer fuse
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? |

Replace the thermal fuse with another; they're inexpensive. Ken. |

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. mike -- Return address is VALID. Wanted, PCMCIA SCSI Card for HP m820 CDRW.

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. |

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? |

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. -- Jerry G. ====== "Martik" wrote in message news:53gGd.99402$dv1.20093@edtnps89...

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.

Lets put it this way as the commercial states:
Thermal fuse... $1.00 Price of a new hair dryer...... $15.00 Someones Life........ Priceless! Regards, Sal Brisindi http://www.tuberadios.com |

James Sweet: 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. electricitym |

I am sure that I am not the only one who had this reaction after seeing your BAD ADVICE reply post. electricitym Holy crap, calm down, I stated clearly NOT to do this, as in DO NOT TRY THIS AT HOME but that *I* would probably (knowing full well it's not a particularly great idea) do it on a hairdryer, nothing else I can think of, but a hair dryer, something that's plugged in for only a few moments while I'm using it. Not a coffee pot, not a heater, not anything wired into the house, but a hairdryer. As the warning goes, I'm a "professional", don't try this at home, if you do and it burns the place down, that's your own stupid problem and you don't need my "advice" to do that. I know I have a heck of a lot more dangerous items around my house than a hairdryer, modified or not, it's simply low on the list. (and no, I have not personally ever bypassed a thermal fuse in anything, never had one fail without the device being destroyed beyond any point of repairing anyway) That said, I've had several "protected" unmodified devices go up in smoke before, a few that if I hadn't caught in time quite likely would have started a fire, a couple cheap space heaters, an air purifier, and a computer power supply all come to mind. After those I don't tend to trust any electrical device particularly and no longer leave any heating appliances running unattended. |
