5. Check the voltage between terminals 3 and 4.

Door position

Voltage (3-4)

Error detecting

Vent

0.4 ± 0.15V

Low voltage :0.1V or less

Defrost

4.6 ± 0.15V

High voltage :4.9V or more

It will feedback current position of actuator to controls.

6. If the measured voltage is not specification, substitute with a known-good mode control actuator and check for

proper operation.

7. If the problem is corrected, replace the mode control actuator.
