My grandmothers dryer wont heat up. It is a Kenmore, (model) 86870100, with (serial no.) MX1661182. Would like to know how i would know for sure if it is either the element or a fuse.

Hi Robert.

Thanks for the pics. I operate in UK and color codes here are different.
From what I can see the wiring in your picture does not match the US standard either.
The thermal fuse for example should have two blue terminals, not red and blue. The thermal fuse wires goes on one side to start, and on the other to the drive motor through the broken belt switch (if present).
The wiring at the blower must be revised and done again.

Here a service manual covering Kenmore 70 series dryers.

There is a wiring diagram at page 25.

Here a picture showing correct wiring: http://www.applianceblog.com/mainforums/attachments/sears-kenmore/3298d1196129125-kenmore-dryer-model-110-86870100-wont-heat-ldrwp-checkpoints.jpg

About the red and yellow cable, the only red yellow wire in the diagram operates the switch for the guard function. The wire becomes hot and powers the motor when the guard switch is closed.

i have the same dryer with the same problem let me know if you find out how to fix it. i think it is the heating element.

We bought ours new in 1989 but have seen posts stating this model started in 1987.

I think what you have is a 110.86870100 made by Whirlpool for Kenmore. Hard to tell the date from the serial number BUT.. there should be a mfg date somewhere on the back or maybe inside. If you are looking for a repair manual, try ebay or a general search on Google. Be sure to add the "110." to the model number when seraching... All I can say is that it's old..

IT IS POSSIBLE THAT YOUR DRUM SUPPORT & BEARINGS HAVE GONE, WAS IT SQUEEKING & HAS DRUM DROPPED SLIGHTLY??
IF SO ID SAY THAT IT IS THIS MINE WENT WRONG A FEW MONTHS AGO, SO I TOOK IT TO BITS & IT WAS THE ABOVE PROBLEM, JUST AN IDEA OR YOUR MOTOR HAS PACKED UP, OR YOUR DRUM BELT HAS SNAPPED..

Check the thermal fuse first, then the heating element.

this kit mounts on the heater element chamber. The small one will be open. The big one failed also because it is rated to shut down @250°F. The little guy is rated at 300°F. NOTE: when this limit fails it is a sure sign of a blockage of lint somewhere.

make sure your door switch is good / if not the dryer wont start / larry

that one is old enough to vote..if filter on top remove back find small hole on right just below top may be hidden by pasted on tech sheet..through hole insert long socket 5/16 or reach up from underneath with short ratchet and socket remove screws and attached wires lift element housing up slightly and pull bottom of housing out and down..5/16 screw on backside holdes element in

The dryer will not heat i check the vent to make sure no upstruction and open the back to make sure no wire was lose. where will the fuse be kenmore model 76722697 serial No. 0702383
