The limit will come off with a screwdriver. Just prise it off there. No drilling needed. The heating element does not come with a limit. You must use the old one.Slide a thin blade under the fat lug to the heating element and it will come right off.

You guys are the best!

Does anybody know of a parts store in Eastern MA that I might be able to go and pick up the heater element myself instead of waiting for delivery?

does it matter that the replacement part you suggested is only 5200W?  The part that came off my dryer is 5400W

I was searching through the site and found this thread, which helped me on my Kenmore dryer problem back in December.  At the time, I found that my thermal cutout had no continuity and all other fuses/cutouts/limits were okay.  So I replaced that part, and the dryer began working once again.  In fact, it worked better than it had in probably years, drying clothes hotter and faster.

I'm not sure why the cutout died, I checked the exhaust vent and it was clear, and didn't notice any other issues.  I clean the lint trap regularly, pretty much every load or every other load.

But, once again, my thermal cutout has died, and I'm not certain why.  I'm hoping one of you experts might be able to help me out?

For reference, this is a Kenmore Series 70 Electric Dryer, "Extra Capacity" and was purchased in 1998.



Thanks in advance!

Remove the lint chute, the the big old box the filter lives in, wash it out good. Then replace the flex vent pipe going outside and make sure the vent is open. Or keep on buying limits.

Thanks!  I'm really not interested in buying new limits every 3 months, so I think I'll try it your way...  :)

Okay, I've removed the lint chute and it had some crud in it, down at the very bottom.  It probably blocked about 15% of the opening.

So I have three questions, if anyone is around to help answer them:

1) Would a 15% blockage of the exhaust from the lint chute cause the thermal cutout to blow?

2) The 4" vent duct is bent a little bit, slightly crimped, maybe about 15% blockage as well.  Could that be a contributing factor?

3) I've read on other DIY forums that the lint trap screen itself can build up a sort of "film" that can only be removed with soap and water.  So, when you remove the lint, you're still not cleaning it well enough to keep it from becoming too hot.  Is that true?  Does that make sense?  And if so, how often should it be cleaned with soap and water?

Thanks again, so much, for your help.  This is a great forum with fantastic contributors.

Yes to all questions and I use a whisk broom to clean my filter. Those replacement filters are 30 bucks and banging them to get the lint off is not practical.

Great, thanks again for the help JWWebster.  I've thoroughly cleaned the filter, lint chute, replaced the ducting with new, and replaced the thermal cutout.  It's working now and hopefully I won't be back any time soon with questions on the same appliance...  :)

Well, it seems like the thermal cutout blew again.

The vent to the outside is one of those that has the flap that pushes open when the dryer is producing air pressure against it, and flaps closed in its normal position.  I checked its movement and it moves freely. The dryer worked just fine with this vent for 8 years.

Is there anything else I can check that might be the problem? 

I really don't want to trash this appliance, other than this issue it's in fantastic condition.

Thanks again in advance for your help.

Is it the top one shown here the one that keeps blowing?

Yes sir, that's the one that keeps blowing. 

And I honestly WISH the vent looked like that, then I might have some explanation for why it keeps blowing.  :(

Thanks for your time,

How long is your vent and how many bends does it have?

You is gonna have to unclog that vent. Just an itty bitty bit of crap in there is all it takes.

The vent duct is about 3' long and has two 90-degree elbows on it, one immediately after the dryer outlet, and one immediately before the exterior vent assembly that goes through the exterior wall.

That rules out a too long vent. Did you check the blower to see if it was loose or slipping?

When I had the lint chute off for cleaning, I spun it to see if it had any dirt buildup within its fins, and it seemed to spin okay.  But I can certainly check again-- anything to keep from trashing this unit and buying a new one.

Thanks as always for your help.

Did you replace the Hi-limit t-stat as well as the thermal cut off?
If not you should.

The larger limit at the base is supposed to trip at 250f the smaller one trips at 300f
If the smaller one on top is tripping that means the bigger one on bottom is bad also.

Have you tested the operating temp of the unit? It could also be the operating thermostat that is allowing it to overheat.
