We cleaned the vent and air duct complete and the temperature should be fine to us. On delecate option, the preset temperature is low; however, customer is not happy that he is not getting the low temperature. He thinks the temperature is still high after we ceaned the unit as much as we could. Is that the main board issue, temperature sensor, or normal? Thank you in advance. It is a Samsung Dryer.
Cleaned duct and filter area.

Hello
Have you seen any error codes come up after diagnostic mode ? Do you have a digital tempearture meter with a probe to check the temperature in each setting ? Have you checked the thermistor resistance ? Have you run the dryer with the vent off to see if it operated properely ? If it is a long vent with more than 3- 90 degree elbows it can cause this issue. Have you verifyied it has the most current software version ? See complete diagnostic link below for more detailed testing and two service bullitins.
Software Version Test Mode
How to Enter:
Press Temp + Mixed Load Bell Keys for 3 sec during
Power On State.
Press Temp key for 3 seconds (until beep)
Note: Test mode subject to change without notice
Testing Electric Heater circuit.
Disconnect White wire from RY6, turn power on, start dryer read voltage between RY6 Blue wire and CN6 Green wire.
Disconnect Orange wire from RY7, turn power on, start dryer read voltage between RY6 Blue wire and CN6 Green wire.
Reading of 120VAC means a proper operating heater circuit. 0VAC means open in circuit.
One heater reading 0vac means that heater is open.
To test thermostat use ohm meter on lowest scale, any resistance replace component
See page 4 for Main PCB layout for testing.
CN6
Low Heat (Delicate/Gentle) ———— 125°F
Medium Heat Permanent Press)——-135°F
High (Normal/Cottons)————- 140°F
