No source. Just tidbit from me!
I had a fire in my dryer this weekend. 3 different repair people, including PS&G (public service elect & gas) said they have been seening high levels of fires in my brand, Kenmore, all models.
Something is not working right with the Kenmore lint collector. High amounts of lint/dust/dirt is getting into the motor and catching fire. I have a gas model and am lucky it burnt out without igniting the gas.
Repairman said to never leave the dryer running when not home (Kenmore, anyway).
For 50 years, Kenmore brand was the work horse of the appliances, that they are having problems like that is scary.
Do you ever vacuum it?
When mine was in the house, I would remove the lint trap and stick the end of the vacuum in the opening.
I hear that crock pots and bread machines should not be left on and not watched.
Not much is safe today.
Thank you for the warning, those with dryers need to pay attention.
Scary is a mild word for what you felt, while it was happening.
