My dryer cycles and heats, but seems to over heat after two cycles and needs about 45 minutes to cool. Is this a thermostat regulator issue?
Answer Hello Rob,
Most times when there is a complaint of the dryer getting too hot there is one of several issues taking place. If the unit is in a small laundry room and the door is closed during operation, this restricts the air inlet into the machine and will cause it to run too hot. The cool air in the room is what cools it and keeps the normal operating temperature down to normal. There has to be sufficient air intake to circulate the air through the unit properly and to dry the clothes in a timely manner. Another thing that can cause this is a shorted heating element. This will normally cause the complaint to change a bit in the sense that it will be too hot even after the cycle has completed. There can also be a restriction in the exhaust duct causing the heated moist air in the unit to be blown past the felt drum seals, back into the dryer cabinet where the normally room temperature air should be. This causes the heated moisture to be recirculated back across the clothes and across the heating element again. This makes the temperature too high and since the moisture is recirculated across the clothes, causes an extended dry time. There is the possibility of a bad thermostat but not quite as likely since most thermostats will either stick closed or not make electrically when they close. Before I did anything to the dryer itself, I would check the complete run of exhaust ducting, making sure there are no crimps or clogs and if flexible is used, check for water pooling in the duct. It is also many times overlooked, but the outside vent will sometimes have a "grille" over it that can clog with lint. Note that all of the manufacturers recommend strongly against the use of flexible or semi flexible ducting since it causes so many problems.
My dryer is taking 2 hours to dry. Already checked the vents and are clean. Do I need to buy a new thermostat?
Answer Hello Lili. If the dryer is heating, it is most likely an air flow issue. Check and see if the blower wheel is clogged. Also, check the duct inside the dryer.
