Whirlpool Dryer Model #LEQ8621PW1
« on: January 31, 2014, 07:45:33 PM »
This dryer had a burnt out high limit safety [279769 Kit).  Replaced kit and checked vent and air flow.  Both were fine.  A short run and a clean hose.  Customer called after one load... no heat.  Replaced kit a second time and replaced operating thermostat.  After one load high limit burnt out again.  Checked voltage at plug.... 249.8 V  Suggested having power company check incoming voltage.  They determined that although high; it was OK.  I also suggested having the house wiring checked by an electrician who also said the everything was OK.  Electrician and power company both blame dyer.  I again replaced 279769 kit, started dyer and did a temp check for 10 minutes at dryer vent without a vent hose attached.  Temp went from approx. 130 to 175 degrees.  Customer called... no heat after one load.  Suggested a new dryer.  This is bugging me so has anyone any ideas?  I still think that it's the high voltage.   
 
Thanks, Don.

  Probably a grounded heater element. If grounded at the end near hi-limit connection, it will have 120vac across it all the time regardless of thermostat cycling. 220-250vac to house is normal range but even if voltage was high, thermostats should regulate temperature. With grounded element, they are not able to.

Thank you for the reply but I checked that too.  I even replaced the element just to pacify the customer.  That's why I'm still stuck on the voltage.  I'm stumped and hoping that this has happened to someone else.

Model whirlpool dryer GEW9250PW1 duet dryer with same heating element uses 279973 this kit and i find that flat safety that is blowing on yours seems to me is to sensitive and blows for no reason.That being said i use the hi limit from this kit that is rated at same temperature.After you put in new heater you should check for grounded heater again just in case the heater coils get bent down after installing.And that heat going from 130 to 175 is a little weird to when the cycling thermostat is rated at 155F.Hope you are using F.S.P parts for this too.

  Is it the thermal cutoff that is blowing? The hi-limit is a thermostat and does not normally fail unless it is physically burning up. Hi-limit is at front of heater box, thermal cutoff further back. Sure sounds like an airflow problem. Did you remove air duct assembly at back of dryer and inspect inside of it? Also inside blower housing? Inside exhaust duct? Blower housing cover seal?

I meant to say thermal cutout in my reply and your right about duct work should go inside if he remove it as i seen this on calls too.
