Whirlpool model no LEB6200KQ0 will only dry on the

Judging from the model number, this is an electric dryer. There can be several things wrong with it. I would start with the vent. Make sure it is not clogged (especially at the end) or kinked behind the dryer. Also, check your breaker. Electric dryers can run with one half of the 220v breaker tripped. Try switching the breaker to the off position and then back on. That may solve your problem, but if it returns, you will need a qualified electrician or appliance service tech to see where the problem is originating. If neither of these help, you will need a tech to see whats going on inside the dryer. hope this helps
