Why is there no air coming out when the air conditioner is heating?
1 Answers
During the preheating stage, the outdoor unit of the air conditioner needs to defrost, or there may be an issue with the air conditioner, which can result in no air coming out when heating. Here is a related introduction to the issue of no air coming out during air conditioner heating: 1. Reasons why the air conditioner does not blow air when heating: (1) When the air conditioner is heating in winter, there is a preheating stage after startup. The outdoor unit starts working first, and the indoor unit will only begin to blow air once the temperature of the indoor pipes starts to rise. This is because the air conditioner has a cold air prevention function. (2) Another possibility is that the outdoor unit has frosted up shortly after startup and needs timely defrosting. During this stage, the indoor unit will not work. Defrosting usually takes about 10 minutes, and hot air will continue to blow only after defrosting is completed. (3) If it is an issue with the air conditioner, it means the heating-related components are not functioning properly and may be damaged or faulty. 2. Solutions for no air coming out during air conditioner heating: (1) If there is no hot air within the first 10 minutes or so after turning on the air conditioner, wait for a while and check if air starts coming out. (2) Check if the fan wheel is stuck. If the fan wheel rotates automatically, inspect the indoor temperature sensor and pipe temperature sensor. This is because the air conditioner heating process includes a cold air prevention phase. (3) If the issue is with the heating components of the air conditioner, it cannot be resolved by non-professionals. Therefore, you will need to call an air conditioner repair technician. Repairs are free during the warranty period, but you will have to pay for them if the warranty has expired.
