    THERMO KING TS200 Insufficient Cooling



    Hi, i am new to reefers and maybe my case may have been looked at already.
    I have a TS200 unit that is only achieving 1 deg celcius or 33.8F as its lowest temp. What could be the cause to this problem?

    It could be quite a few things or multiple things, start with the basic stuff and go from there.

    Is the condenser and evaporator clean and clear of ice, are the condenser and evap fan(s) running and spinning in the correct direction.

    If theres a liquid line sight glass, see what it shows you.

    Check the pipework and compressor temperatures.

    Check that it is still trying to cool and not just a fault with the thermostat/controller switching it off too early.

    Are the doors closed properly? Are there people going in and out of the box too frequently? Is there too much stock in the box? Has someone blocked the air flow of the evap or condenser?

    Theres a engine throttle/speed solenoid youd probably start with checking.
