** kenmore dryer ... Pushing start button results in a nasty noise. I am looking for a guiding hand. **
"Kenmore" branded products are made by any number of different manufacturers each of whose products designs can vary from model to model. The first thing you should do is post the *complete* model number as printed on *the appliance's model and serial number tag* so we can find out what machine design you're dealing with.
You can find tips for locating the model and serial number tag on your appliances in the 'Repair Parts' section of my site linked below.
