I was told that I should get a reading of 10-50 ohms on my dryer element.I get a reading of around 10 on my element, but this is with the multimeter set to 200, so the reading is around 2,000 ohms.The guide I read said to set the meter on the lowest setting, but I wondered if "10" was the actual number, or if they really meant 10.
If I get a reading of around 2,000 ohms on my heating element, does that mean it's bad?
I shorted the thermal cutoff to make sure the dryer works, I plan to replace it.
Why did the thermal fuse blow?Is the heating element overheating because of the higher resistance?
I don't want to replace the thermal fuse and have it blow again because I did not find the cause of the problem.
I'm pretty sure your reading is 10 ohms.Sounds about right.If it's close to that, check the rating on the dryer.What is the thermal rating?
If the circuit measures a low resistance to the dryer case, you should check the wiring.It could be a stressed fuse that went over time if all checks are good.If you have an ammeter, make sure the running current is in line with the rating on the dryer.If the thermal fuse is hard to get and expensive, then replace it with a temporary one that has the same rating.
