SOURCE: Have roper electric dryer. That will not start.

Yes as suggested it can easily be confirmed iff you can use a multimeter and trace the power cord to the dryer. The fuse can be found and it must be the fault if the main switch ois working- test with the meter for the switch continuity to confirm.

Roper dryer heats

Hello James,

The reason the clothes are so hot and the cause of the thermal cutoff going out in the first place was due to very poor air flow through out the dryer causing excessive heat to be built up in the dryer. What needs to be checked is for built up lint in the blower housing and or a blocked/ restricted vent tube.

Dryer runs, no heat, element OK 10.5ohm, Hi limit thermostat .8 ohm, next one is thermal cutoff or operating thermostat, open no meter readings. Part # FSP 3399848 could this be my problem? Thank You


Both the Thermal cutoff and the operating t-stat should have ZERO ohms resistiance 0.8 is fine but open on either they are bad

That part number you have listed is what ya would need..even if only the thermal cutoff is open replace both the thermal cutoff and high limit t-stat at the same time

also if the cycling t-stat is open replace it too...if its fairly modenr and hasa digital display the cycling thermostat is a thermister and at room temp that will be about 5.8 thousand ohms

if has timer the cycling t-stat will look like the high limit t-stat and should be closed

I cannot afford a service tech right now to come to the house. I hope you can help me through this service. I have a kenmore elite clothes dryer model # 110.63012101 Dryer was not making any heat. ...

you're doing the right thing except for changing out the element without reading it out first.when you check the parts make sure the dryer is unpluged and that you pull at least one of the wires off the part you're checking. check the thermostats on the heater box part
279769 which is part 47,also remove the duct that the lint filter slides into and clean it,if you have a long vent line remove it from the back of the dryer and blow it out with a leaf blower and if you have a shop vac put it on blow and blow off the motor and blow all the lint from the back inside of dryer so it blows to the front and vac it up so you don't have to pull the drum if you don't want to.the thermal cutoff pops when it gets to hot in the dryer most likely from a back up in the vent line or the duct,also go outside and make sure the vent is clear,you should be fine

I have a kenmore series 80 dryer and i have check the element and it gets 9.4ohm i have check the themal cutoff and that has resistance but the cutoff-tml has no resistance and i dont know if it is an open...

Take a looke4cac94.jpgNumber 1 is open no continuity? That is the problem. The cause of that one blowing is air restrictions.f73ac85.jpg03d0579.jpgVent clogging definately makes that smal limit go bad. If it ain't got continuity it is bad and its cousin
number 3 in the photo above is bad also even if it has continuity.
Why? because it is supposed to shut off at 250f. The limit above it dies at 300f so both are bad and both come together in a packaged9444e5.jpgThe timer is easy to check clip a lead of your meater to the terminal marked RH after you have removed the fat red wire going down to the heater. Try and get continuity from any other terminal on that timer. Turning that timer. If you cannnot get continuity you have a burn leg (very common). Manual and more HERE9994972.jpg

Kemore dryer model110.67522600, checked continuity on heating element,OK, Thermal fuse OK,cutoff-tml ? Thermostat #3977767 no continuity.Thermostat #3387134 ?

Both the high limit thermostat #3977767 and the operating thermostat #3387134 are normally closed switches and should have continuity. These thermostats are usually replaced as a set because when one fails its often caused damage to the other. The part # for the kit is 279816 and comes with both and is cheaper than if bought separate

Can't control heat setting

Either your dryer vent is clogged, the blower wheel is striped out and not turning or the internal bias thermostat you bought is bad. These are the only things that can make the dryer over heat.
