Which of the following is NOT a possible cause if a manually controlled air conditioner or heater is not delivering the proper temperature of air? a. The cable is blnding b. The actuator is unplugged c. The cable is broken d. The cable has become disconnected at the door

The correct answer is a. The cable is binding.<br /><br />The other options (b, c, and d) are possible causes for a manually controlled air conditioner or heater not delivering the proper temperature of air. If the actuator is unplugged, the cable is broken, or the cable has become disconnected at the door, it can prevent the proper functioning of the air conditioning or heating system. However, the cable binding is not a common cause for this issue.
