SOURCE: Error Code E68 stuck button?

control boards for this model are as low as $146.00 on ebay, although the code 68 "button stuck " issues 's I've found have been the start button switch ,found one at the local electronic store[close to what's on the board , but not exact !] for $3.99 fixed one for a customer of mine [just to see if that was indeed the problem]. Been running for the last year so far

SOURCE: Replaced all control boards in kenmore elite dryer and still get f70 code

ok i copied and pasted this...but its good info...



F70 = Overheating sensed causing dryer stop until temperature reaches(drops) below set level - determined by manufacturer

Can be caused by different contributing factors;

1. poor airflow

2. blocked air flow screen inside tumbler

3. clogged lint screen

4. slow tumbler (low revolutions)

NOTE;

Ironically, the fourth factor has been lurking behind the popular discussions on this problem that has exhibited itself on both the whirlpool and Kenmore products with the main triage to have included inspection of the electrical connections made by the installer.

These electrical connections not followed properly with accordance to '4prong' NEMA 14-30R (30amp, 2-phase circuit outlet) with separate ground and neutral posts, as exhibited in the standard dryer installation manual, will cause your tumbler to run slow. Hence, the 4th factor which caused the 'F70' code stops the dryer from operating.

Now, you have corrected the wiring as necessary and eagerly place some stuff's in there and all seems well. But as soon as you place something large and wet (HEAVY/BUNDLE), you get the error code again, you thought you had it!

Okay, this is what you need to do;

1. make sure your air flow is adequate by really cleaning the duct (I stuck my hand through the wall duct and scraped off old hard lint that can collect humidity & even cut my finger). Also make sure your vent hose does not have any unnecessary elbows or squiggles in it ( I had an elbow/pan type and it is not good as the heat seems to reflect too much ). KEEP IT AS SHORT AS POSSIBLE - I KNOW IT'S HARD, BUT IT IS NECESSARY.

2. Refrain from using too many softener sheets as they can & will restrict the air flow screen inside the tumbler.

3. Make sure your lint screen is clean - wash it periodically as lint particles collect moisture and this in turn raised humidity.

4. Once you have verified your electrical connections as stated earlier in this posting, run a normal cycle with towels or something of the like so as to reset the sensors in the dryer.
.

THE MAIN THING TO REMEMBER IS THAT 'F70' SEEMS TO BE THERE TO PROTECT AGAINST OVERHEATING WHICH IN TURN CAN TURN TO A FIRE HAZARD!

The tech sheet kindly provided by a member on another forum shows F70 as a control board issue as noted in this thread.

So what did I do so far:
Opened the top and back panel and thoroughly cleaned the lint. I did not however ,think that the lint was excessive as to cause motor malfunction. I also unhooked the dryer from exhaust and ran three loads and they all dreed without the error. Now it is possible that removal of lint did the trick but it looks like the venting issue as suggested in one of the replies has some credence. next I will hook the dryer back to wall exhaust and run a few loads. if the error returns I will focus on venting.
The main question that I am asking myself is that if the control boards are at the heat of issue would it possible to do any loads without the error. Your comments and suggestions are very welcome.
I hope all this works ends up in a running dryer and helps other people struggling with the same problem.
