I have a westbend countertop oven toaster oven broiler Model #6210 Date code 0030 1500 watt. The light comes on that tells me it's on but none of the elements work I have had tis oven for several years I don't remember when I got it. Can I get parts? an element or thermostat whatever could be wrong? Or should I just ditch it and buy a new one. I really like it and I'm use to it. Thanks for any advice.
