After reading this page we purchased the coil kit for our Kenmore Series 70 dryer,installed and it wasn't the problem.On "More Dry,"(and probably the other settings.Haven't tried them all), it just keeps going and going. We've jumped all the fuses too.

PLEASE HELP !

... Igniter Glow? No
Then it wouldn't be the Coils,

Have you checked the Igniter ?  (may be 400 OHMS at room temperature)

WHIRLPOOL Dryer Igniter Kit and Bracket, part number: 279311




Have you checked the Thermal Fuse?

WHIRLPOOL Dryer Thermal Fuse, part number: 3392519



Is there any heat from the Gas ?

When you replaced the coils did you clean out the dryer by taking it apart and throroughly removing all the lint build up including the outside vent? If the dryer needs cleaning then it ain't gonna run right.

I don't see a spark when I'm looking through the eyehole of the dryer.Should I check it with a meter anyway?Could it just be dirty? Do igniters get dirty or should it be replaced. Thanks!

It could be, but without testing it I couldn't be sure.

Ok,will do.I need to borrow a tester from work and I'll test it late tonight,(get off work at midnight), and get back here with my results.I'm happy I found this EXCELLENT site.Your team has been superb in answering my questions at lightning speed.We use this old dryer to help with our volunteer laundering work for a local shelter so it's vital we get it up and running asap as we really don't want to start using the dryer in our home or at a laundromat! Thanks very much.Get back with results later. :)

Now that everyone has added their comments, I would like to add for you to check the radiant flame sensor on the left side of the burner box. It has a black and a white wire going to it. If you unplug the dryer and disconnect those 2 wires, use your OHM meter to check for continuity across the 2 terminals of this device. You should show full continuity if it is good.


The reason I brought this up is because I have sold 5 radiant sensors just this week. Appliance parts seem to fail in bunches, for some reason. I will sell lots of one particular part for a week, then won't see them again for several months. I firmly believe it has to do with moon phases or something  ;)

Let us know what you find.

Just wanted to thank you folks for all your help.  O0 We went and bought a new Amana the other day on clearance at Menards for $225.It's the same "old fashioned" type like the old one but it's perfectly fine for our volunteer work.If it dries that's all that matters!! Can't beat that price and hopefully it'll last 10 years.Well thank you again and we have your site on our favorites list for future reference and help.HAPPY HALLOWEEN  ;D

PS:The comment about appliances breaking down in bunches with phases of the moon is REALLY FUNNY because we noticed 4 dishwashers sitting out for trash pick-up in our neighborhood last week !!

It may be worth it to buy a meter for future repairs, whatever caused the old Dryer to go bad... clogged vent, etc,

M-L Digital Multi - Meter, part number: MA-DM1

It may also be worth to fix the old Dryer.

That's an excellent suggestion.The worst part of the whole dryer fiasco was we couldn't return the coil set and get our 32 bucks back.Since this was our first time dealing with this sort of thing we didn't know.We called and asked if we could return the set and pay the difference/exchange for a different part we may have needed after testing.They were like,"Sorry.No can do!" We were going to use the tester and go from there but then we thought what if the same thing happens again and we buy another part that isn't what we need and can't return?? We hauled the old one away and I gave it to a guy at work who's dad takes things apart for parts and sells them.So we contributed to his appliance parts shop which is good. Anyway,the 200 bucks we put out for the new one is nothing compared to the almost 2,000 bucks we spent 6 months ago for the washer/dryer in our home! THANKS AGAIN to an awesome helpful site!!  :D

I will try to post this here before starting a new thread, but I am having the same problem with my 70 Ser gas dryer.  I have replaced the 2 coils, but still nothing.  I was reading about testing the OHMs of the thermal fuse and I am not sure if I am doing it right.   

I am kind of new to the fluke meter, but I think i have it on OHMS.  When I test the two terminals, the meter makes a noise and will jump around as far as the numbers on it go.  I have seen it as high as 50 but it usually settles down to 1, and then to 0, but still beeps....

Am I testing the correct part the correct way?

I get no glow at all from the coils.  I replaced them.   What is next?

Thanks

Based on your I reading on that high limit and from what those tutorials teach I would say that limit of yours is bad. Do you concur?
