Why is there no air coming out when the air conditioner is set to heat?
1 Answers
Here are the specific reasons why the air conditioner does not blow air when set to heat: 1. The heating mode takes about 5-10 minutes longer than the cooling mode to start blowing air, as it hasn't reached the preheating time yet. After turning on, the air conditioner first performs defrosting before normal heating begins. 2. The four-way valve may not be open, or the valve itself could be stuck, or the electrical control may not be supplying voltage to the four-way valve. 3. The air conditioner requires refrigerant (Freon) to operate. If the refrigerant is insufficient, the unit may fail to work or temporarily stop functioning. It is necessary to call a professional to refill the refrigerant promptly. 4. The indoor pipe temperature sensor might be damaged.
