Dryer Fire
« on: April 08, 2014, 02:47:05 PM »
I am investigating a dryer fire that occurred in November 2012. It is a 5 or 6 year old Whirlpool model: IFR8200 made in Italy.  Appears that the fire started in the drum but there was no indication that the clothes being dried were stained with any solvents, paint, or fuels.  Two jackets with metal zippers were being dried along with pants and shirts.  No cigarette lighters either.  This dryer had a moisture sensing circuit but not too sure if the zippers could cause a short in this circuit.  It seems the energy in this circuit would be minimal so not a likely ignition source.  Lint screen and block exhaust not likely either as they were clear.  Anyone know if zippers causing fires?  I need to find out if there were any service pointers on this dryer.  A schematic of the electrics would also be helpful.  Can anyone point me to this info?  Any suggestions or theories would be helpful - off to check t-stat opening temps.

Thx in advance,

clothing starting on fire in the dryer drum is rare, in 20 years I have seen it once. If no flammable vapors were present in the drum the most likely cause would be a build up of lint on the dryer floor under the drum which starts on fire burns the belt and stops the drum from rotating and this point the clothing would be sitting at the bottom of the drum with the fire directly underneath heating the drum to over 500 degrees until the clothes ignite.

The overload thermostat usually prevents the dryer from reaching lint kindling temperatures. Check to see if there was a short  in that item.

Thx for the tips guys - all 4 t-stats were checked and all 4 do open at approximately their specified setpoints (50C, 90C, 95C and 150C).  Going to ohm-out the motors and then re-assemble the dryer and see if it functions as expected.  Apparently there were two jackets being dried at the time of the fire.  One was likely polyester or polyurethane-based.  From checking the tags on other similar jackets, these materials are not to be dried in a dryer or bad things can happen...

I worked in this business for over 40 years now.    When something catches fire,   it usually was because A - clothes or items being dried had a flammable material on it or B- Item should not have been dried in the first place -    Used to get blankets or jackets catch once in a while in commercial dryers.   The Label on most of these would say - AIR DRY ONLY - DO NOT DRY IN DRYER>    Had one once,   drum smelled like paint thinner.    Guy threw in rags doused with paint thinner into dryer.     But in general,  a dryer drum fire is rare -  have seen few of them in 40 years.
