GENERAL INFORMATION
Dry Cycle - Theory of Operation
The illustration below gives a brief description of the components involved specifically on a Dry Cycle. Knowledge on the
system's physical parts is needed in order to properly diagnose and troubleshoot the "all-in-one" washer/dryer.
1. Blower - Generates process air flow through the heater
channel, tub, and condenser duct.
2. Air Heater - Heats the air so it gets into the tub at high
temperature and reduced relative humidity.
3. Heater Channel - Conducts hot process air into the tub, so
it can remove humidity from the laundry.
4. Inlet Air NTC - Used as a feedback for the air heater
Control Software.
