The reason why the freeze dryer does not cool due to the failure of the refrigeration host "Experience Sharing"

　　There are many reasons for the freeze dryer not cooling, and one of the most common reasons is the failure of the refrigeration host. The following are several possible causes of freeze dryer refrigeration host failure:

　　1. Insufficient coolant:Coolant is a key part of the refrigeration host. If it leaks or is insufficient, the refrigeration host will not function properly. Therefore, if you find that the freeze dryer is not cooling, you must first check whether the coolant is sufficient.

　　2. Refrigerant leakage:If the refrigerant leaks, the refrigeration host will not be able to operate normally. To check whether there is a refrigerant leak, you can check the high and low pressure gauges on the refrigeration host. If both pointers are outside the normal range, there may be a refrigerant leak.

　　3. The internal parts of the refrigeration host are damaged:Every component in the freezer needs to be in good condition to ensure its normal operation. If one of the components is damaged, the entire freezing host will not work properly. For example, if the fan motor burns out, it will lead to poor heat dissipation and damage to other parts.

　　4. The refrigeration host is overloaded for a long time：If the refrigeration host is under high load for a long time, its lifespan will be shortened and it may even malfunction. Therefore, when using the freeze dryer, be careful to avoid long-term continuous operation and perform regular maintenance to ensure its normal operation.

　　We will briefly introduce here the "experience sharing" regarding the reason why the freeze-drying machine does not cool due to the failure of the refrigeration host. In short, in order to ensure the normal operation of the freeze-drying machine, it needs to be maintained regularly, and any possible problems should be discovered and solved in time. Once a problem is discovered, be sure to contact professionals for repairs in time to avoid more serious losses.
