The upper dryer seems to get too hot. It is warping the clothes trays. There are no warnings associated with this. Is there a thermostat ?

Paul for Model Number MCE8000AYW

ANSWER Hi Paul. A couple of things can cause it. First: Make sure the vent is entirely clear and not restricted. Make sure the outside vent cap / hood is opening and closing properly 4-5x /yr. so lint and moisture does not back up and create a restriction causing these issues. Second : Use a volt/ohm meter part # TJMA-DM1 to assist you in your diagnostics. There is a thermistor mounted on the blower housing. It is 31001590. If it has shorted then it will allow higher temperatures. Then replace the hi-limit thermostat part # 31001689. And also the thermal fuse part # 31001690. Ohm the heater to see if it has shorted against the case. It is no longer available. Thank You.
