    Good morning, congratulations on the channel. I wanted to ask you a question. I bought a used freezer cabinet and when I turned it on it worked strangely, the compressor turns on, stays on for a while and then turns off and doesn't reach temperature. To understand better I excluded the control unit and connected the compressor, evaporator fans and condenser directly to AC. Unfortunately the compressor continues to turn on and off. I noticed that the compressor's absorption while it is working (not at start-up) is 1100 watts, when according to the plate it should absorb 600 watts (the two fans together consume about 100 w). What could be the problem?

      Check relay, overload, and run capacitor first, if still persist replace compressor. But before doing so check if there's a solenoid valve that runs together with compressor

    Sir, thank you for your very informative video. May I ask your help. I have a 4 door upright freezer with R404 refrigerant. I changed the filter dryer and capillary. I have another access valve before the filter dryer. Is it ok to charge liquid R404a before the filter dryer side or vapour on the low side? Thank you and more power.

    • @THEMULTISKILLEDTECH
      @THEMULTISKILLEDTECH  2 ปีที่แล้ว +1

      Try it sir since that procedures are discussed in our refrigeration books. In walk in freezer/chiller we charge liquid in low side the reason is refrigerant goes easily into the system.

      R404 between 20-25 psi lang sir for freezer. Pwede ka din magbase sa ampere sir, before ka magcharge check Muna run capacitor if less than 80% n ng value nya change na.
      If 1 HP change with 1 HP, if 3/4 HP, change with 3/4... Gaya ng sinabi ko sir base ka SA ampere at di ka maliligaw

    Plzzz tell how much gas i should charge at how much amps so the compressor will not get hot any more and cooling also be good

      Is your 3door chiller still have label sir? If so, a refrigerant in kilograms is stated therein. Over charging makes your compressor overheat and the overload will cut off the power to protect it.
      In my description I write there our R404A charging pressure and our units are for commercial use.
