It's going thru the defrost cycle. Once that ends, the unit should restart. If it doesn't wait until 3 minutes have elapsed, after the stop light goes out and restart the unit. If that fails, turn the Master ON/OFF Switch to OFF & unplug the unit. Wait 15 minutes, plug the unit back in and turn the Master ON/OFF Switch to ON. The unit should have reverted back to the original factory settings. If so, reset the controls as you like.
