    I have an SB-210 thermoking. When the temperature drops it does not stop at the set point, it continues to drop

    3 way valve might not be shifting to heat which is likely caused by the pilot solenoid not energizing. Put it on heat see if the coil on the solenoid is magnetized by touching it with a small wrench .

    When the fault occurs, it shows alarm 3 and 203. Where the return air sensor is located?
    Thanks for your help

    It has 2 return air sensors,one is for control and one for display.They are located at the lower passenger side of the reefer in the back.They should have a brass clamp on the top of them.If you change them then you have to calibrate the sensor grades in the controller which you might not want to get into.

    I changed the air return sensors but they keep codes 3, 203 and 11.
    Also clean the connectors that go to the micro. When I try to eliminate code 11, which is the only one that allows me to do it, it comes out again.
    Any suggestion

    Yeah you have to go into the guarded access to clear it and and calibrate the sensors try to see if there is a youtube video showing how to do it it's kinda hard to explain on a post

    Modify the sensors in the guarded access in addition to eliminating the errors. I start without problems. Thank you very much for the advice
