Kenmore Dryer (970-C8909700) stops mid cycle. Four lights blink.
The dryer heats up, but stops mid cycle. All four front lights blink. I assume there is an error code being displayed, but I can't find any information about the 970 error codes.
The cycling thermostat cycles the heat on and off to maintain the proper air temperature. If the thermostat is defective, it may keep the heat on too long, causing the dryer to get too hot. However, this is rarely the case. Before replacing the cycling thermostat check all the more commonly defective parts. If you have determined that all of the other components are working properly, test the thermostat by using a multimeter to test it for continuity. If the thermostat does not have continuity, replace it.
Air Flow Problem
If the vent is clogged or partially clogged, it will restrict the airflow through the dryer, substantially increasing the drying time. To ensure proper dryer performance, you should clean your dryer’s venting system at least once per year."
