Dexter Laundry T-750 C4 Installation And Parts & Service Manual page 75

To enter a test Cycle Mode you will have to enter the programing mode:
MANUAL PROGRAMMING:
The dryer must be in idle mode for the manual programming menu to be accessed. Idle mode is when the
dryer is not actively running a drying cycle and the vend price is displayed on the screen.
To enter the manual programming mode, the control tray on the dryer must be unlocked and pulled out to
reveal the programming button. The programming button is then pressed for 1 second. The control should
display "DRYER PROGRAMMING".
See Figure 1
Next press START and you can scroll through the options you will either want to select Quick test or Con-
tinuous Test depending on the length of time you require to preform the tests.
Quick Test Option:
When the Quick Test Option is chosen, the dryer will begin a shortened dry cycle without the displayed
vend price being met. The purpose of this shortened cycle is to test all major components for proper opera-
tion. Error Codes should all function normally during this test. The display will show customer prompts in a
similar way to a normal dry cycle.
Continuous Test Option:
Similar to the Quick Test, when the Continuous Test Option is chosen, the dryer will begin a dry cycle with-
out the displayed vend price being met. However, in this case, it will be a continuously-running cycle. It will
not time out after any designated amount of time.
CAUTION: This option is meant for factory use only. Do not operate the dryer with this cycle active with-
out factory authorization.
