Hi, I'm having trouble with the refrigerador, it's frozen inside the frieze and the other part of the refrigerador it's warm. I replaced the heater and the thermostat and it's still doing the same. I see that it's always running on the compresor and never stop, I already checked the doors rubbers and they look fine, I don't know if I have to replace the tempeture sensors. Please let me know what to do. Thanks
