I have a 2006 frigidaire dryer - works great, but I was cleaning it last weekend and noticed that under normal operation (heating cycle) the back of the unit gets very hot - I measured 180 degrees F!!! Seems too hot to me! The heating coil measured 11ohms resistance - I think that's normal, but maybe it's low? I wodner if the age of the coil means it's getting hotter OR perhaps my high temp sensor is bad? curious what others think. I'm tempted just to replace the coil assy, high temp sensor and other key components just to be sure! REplacing myself is not expensive! Thanks in advance! Dave
