Verify the temperature control actuator operates to the hot position when connecting 12V to the terminal 3 and grounding terminal 4.
Verify that the temperture control actuator operates to the cool position when connecting in the reverse.
Check the voltage between terminals 5 and 6.
Door position | Voltage (5-6) | Error detecting |
Max. cooling | 0.3 ± 0.15V | Low voltage : 0.1V or less |
Max. heating | 4.7 ± 0.15V | High voltage : 4.9V or more |
