Verify that the mode control actuator operates to the defrost position when connecting 12V to the terminal 3 and grounding terminal. Verify that the mode control actuator operates to the vent position when connecting in the reverse.
Check the voltage between terminals 5 and 6.
Door position | Voltage (5-6) | Error detecting |
Vent | 0.3 ± 0.15V | Low voltage : 0.1V or less |
Defrost | 4.7 ± 0.15V | High voltage : 4.9V or more |
* It will feedback current position of actuator to controls.
