1.
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.
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 |
