Door position Voltage (6-5) Error detecting Vent 0.45 ± 0.15V Low voltage: 0.1V or less Bi-Level 1.4 ± 0.15V Floor 2.45 ± 0.15V Mix 3.5 ± 0.15V Defrost 4.55 ± 0.15V High voltage: 4.9V or more It will feedback current position of actuator to controls.
- If the measured voltage is not specification, substitute with a known-good mode control actuator and check for proper operation.
- If the problem is corrected, replace the mode control actuator.
