Explanation of Dryer Temperatures

The internal temperature of a dryer may be affected by several variables. Some of these variables are noted below:
Variable Impact
Load Size and Dampness The combination of these two factors determines the amount of Heat Sink. Heat Sink is the cooling action taking place when the clothes give up their moisture to the hot air stream that is flowing through the dryer drum.
Room Temperature A dryer pulls air in and heats it up to help dry the clothes. Hence, the air temperature of the room may effect the outgoing temperature in the dryer.
Air Flow Restrictions in air flow such as long vents, vinyl flexible ductwork, or lint build up will cause heat to rise rather than following its designed air flow pattern. When this occurs, safety thermostat(s) will sense the high temperature building within the drum and cycle the heat source off until the excessive temperature has subsided.

Listed below are the internal temperature range specifications for dryer operating thermostats in extra large capacity dryers manufactured after August 1992 and large capacity models manufactured after January 1994. Models manufactured prior to these dates had higher acceptable internal temperatures. Most 120V models reach approximately 145F during operation.

Note:  The below table represents outlet thermostat set points and not the air temperature in the drum.  Medium and High Heat have the same outlet thermostat temperature set points however, their technical applications are different.
