    I replaced the thermal fuse and still nothing!??

  • kristaandtra Dec 31, 2008

    Is there a second thermal fuse in my dryer?

  • kristaandtra Dec 31, 2008

    Electric bill is paid. LOL And all the door stuff works fine. While trying to check things out it just started on its own and then wouldn't start again??

  • rickisme Jan 16, 2009

    I have 'almost the same problem,' but the dryer was working and I opened to check on the one item that my daughter was drying and it wouldn't turn back on. If the thermal fuse blew from heat related to lint, seems strange that it only happened after I checked it...might it more likely be the switch....Can you tell me how to test the door switch. Thanks

    my maytag smell like something burnt and now wont start

Ok...almost same problem...resolved by replacing thermal fuse by I guess the thermal fuse can just go with a little surge from opening closing door switch if it was already on its way out...or something...but simple fix anyway....thanks for giving me the order of things to try!

Quick check list starting with the most likely to the mostly likely NOT:
Fuse Roper Dryer Won't Turn On - edfbadd.jpgmounted on the blowers housing this puppy is wired in with the door switch. If the lint in the dryer gets to blocking the exhaust then this puppy gets all hot and bothered and melts, causing the whole machine to come to a screeching halt just as if you have opened the dryer door. Clever ain't it? Clean out the lint and replace this fuse.

    Of couse the fuse is the most likely but if it turns out to be good then the door switch itself would be next followed by the door switch actuator, followed by the timer, followed by the motor, followed by the electric bill being unpaid. Thank you Kimosabe for your excellent rating

    Could be the start switch. Did you try reseting the breaker, check the cord, the receptacle, and the power terminal where the cord connects to the dryer. If all of that is good then I would say you are down to a bad motor or a bad timer.

    Their is not a 2nd fuse. The hi limit would not kill the power to the motor. The door switch actuator could be broken. This dryer has a little arm which sticks out a hole and when the door gets shut on this arm then the switch will have continuity.If that arm breaks then the dryer will not work.

    Are you checking each component for continuity with one wire removed so that you will not get a false reading?

Kenmore model 110.60817990 will not start

I would check the door switch first. Lot of times you can tell right away if it is broken the lever will be loose or you cannot hear a click when you wiggle it. If that is fine you remove the back cover and check the skinny fuse mounted on the filter housing next to the control stat. If it is open remove and clean out the filter chute before replacing that fuse.
I recently worked on a roper dryer which is identical to yours:

Timer clicks on dryer but want work

A lot of times the small white fuse will melt and kill the door switch circuit on these.

I removed a bunch of junk from this one's blower housing/filter chute:

So if your door switch is fine check the thermal limit:

Hello there and thank you for choosing fixya
If your dryer doesn't work at all, it could be because of problems with:
Power from the house Check to see whether there's power getting to the dryer. Is it plugged in? If you plug something else into the outlet, does it work? If not, check for a blown fuse or tripped circuit breaker. Door switch If the door switch or the door-switch actuator is defective, the dryer won't work and you need to replace the failed component. The switch is inside the dryer main housing near the door frame. Sometimes you need to raise or open the top or front of the dryer to reach the switch. To determine if the door switch has failed, watch the part testing video at the bottom of this page. Thermal fuse On many dryers, there's a thermal fuse (a heat-sensitive fuse that blows if the dryer overheats) mounted to the exhaust duct inside the back cover panel. The fuse is about an inch long. It's usually embedded in black resin and mounted in a white plastic housing.

If the fuse has blown, it has no continuity. When this happens, your dryer either just stops heating, or it doesn't work at all. Be sure to inspect the venting/heating system before replacing the fuse to put the dryer back into operation. (You can't re-set this type of fuse.) To determine if the thermal fuse has blown out, watch the part testing video at the bottom of this page.
Wiring Often the main wiring connection from the house, at the dryer, burns and the connection breaks. In this has happened to your dryer, you need to replace the power cord and the terminal block that it is attached too

I have a roper dryer (REL3612BW2) that will not turn on.

If the door switch or the door-switch actuator is defective, the dryer won't work and you need to replace the failed component. The switch is inside the dryer main housing near the door frame. Sometimes you need to raise or open the top or front of the dryer to reach the switch. Here is a link to the part you will need. Below is a video to walk you thru the repair process for the switch.

Dryer wont start on my roper dryer. Timer is working but wont start

Check for a blown thermal fuse. It's about an inch long and is located inside the rear of the dryer usually attached to or near the exhaust duct. It can be tested using a multimeter or ohmmeter. Check for continuity. A lack of continuity means a blown thermal fuse. Sorry for your trouble and I hope this helped. Best wishes.

Roper Dryer Won't Turn On

2b3eba2.jpgThis fuse mounts on the rear blower housing. If lint builds up in the dryer this puppy will melt and shut down the dryer door circuit. It will be just as if you opened the door. Simply replacing it will get the dryer going again but failing to properly clean out the dryer will result in more fuse failures.

My roper dryer stopped working

right above the door where it closes, there should be a door switch actuator, although your closing the door it might not be activating door switch.
