My Whirlpool Dryer LER5636EQ1 has suddenly began to shut-off in mid-cyle no matter what setting we use. It stays on for a couple of minutes then shuts off. Sometimes when we try to turn it back on it won't do anything. I've checked/cleaned the filter many times and it seems to be no help. Is my dryer throwing in the flag? Or can my husband to a home repair?
