Dan L. for Model Number FDE436RE32 Hello, I have an Frigidaire dryer (year200)Model Number FDE43RE32 and about every 6-8 months I trip a Thermal Limiter. I have cleaned the lower lint area numoris times and the venting system. The exterior vent has good presure when the dryer is in operation.I was told there is a washer kit to put space between the heat elementand back panel, for this model to help releave the heat trasfered to the back panel where the Thermal Limiter is. Is this the fix I need to Follow or is there something else? Also isn't the Thermal Limiter resetable or a one time use? When I have disasembled the tripped ones it would seem they should reset? Thank You in advance. Dan Laabs
Answer Hi Dan. Usually a over heat issue will open any thermostat. Since you have cleared the vent system, have you also checked the vent cap to see if it is opening and closing completely and freely. So the rain or the night dew will not back up and re-clog the vent . Are there any sags that will collect the water in the lowest sag and back up with lint? If the heating element is expanded and contracted long enough, it will get weak and eventually touch chassis grounding the element out. Then it will draw too much current and open the fuse part # 134120900. Conversley it can be possible that the cycling thermostat inner contacts can be getting sticky and welding itself together little by little overtime allowing the heater to get too hot. Thinking in terms that will allow the heater to remain on too long. The motor centrifugal switch contacts can also get sticky and do the same as well. The heat circuit "passes" through the motor when the switch closes as the motor is at least at 40% sppeed. Concentrate on the heater diagnose first. This part is # 131553900 . Thank You. Read More...
