3. defrost is not thorough.
Frost can defrost after frosting, but the defrosting is not clean, not thorough, or there is frost on one side, frost-free on the other. This situation is generally due to:
(1) If the defrosting end temperature is too low or the defrosting time is too short, the defrosting end temperature and defrosting time can be adjusted appropriately.
(2) The position of defrosting probe is unreasonable. At this time, the defrosting probe can be placed in the place where the frost is the most serious.
4. Frequent frosting in a short time
(1)check whether the defrosting temperature is normal. If the defrosting temperature is normal, check whether the ventilation around the main engine is good, clean up the debris around the main engine and clean the evaporator, and prolong the defrosting time and increase the defrosting end temperature.
(2) Host frequent frosting and pressure gauge pressure is low, first use hot water to defrost artificially, and then observe the low-pressure meter when heating. If the pressure is lower than the normal value (can be compared with the same type of machine), it can basically be judged that the lack of refrigerant, or refrigerant leakage.
(3)Damage of main fan motor or insufficient air volume, such as blade damage, or low power of fan motor.
We OSB, as one of recommendable heat pump factories, focuses on customer’s feedback.
We supply 2 years for warranty time. During the period, spare parts are free to change.
It is not only support customer selling well at the beginning of OSB heat pump products, but also be a good after salesman for the final customers in case any problems.
Once heat pump has any problems, you can contact us and descripe the problems in details.Then we will trace the production details and discuss with our engineer team. And give you technical supports and instructions.
