  If your Geco Controller appliance isn't reaching the set temperature, verify the user-defined temperature settings and check the values of parameters 'c2', 'c5', 'd0', and 'd1'. Make sure the appliance defrosts completely. Also, check the location and mounting of the chamber sensor. Ensure there are no removed side or front glass panels. Avoid direct sunlight or drought exposure. Check for nearby fans or air conditioners. Ensure the condenser is clean and the shop temperature is within the appliance's operating limits. Finally, inspect the amount of gas, fans, evaporator heater, and evaporator water drain hose.

  To troubleshoot defrosting problems with your Geco Controller, check the values of parameters 'd2', 'c0', and 'c1'. Ensure 'c1' (maximum defrosting duration) is adequate for complete defrosting. Verify the evaporator sensor is firmly mounted to the evaporator lamellas, ensuring tight adherence. The temperature at the sensor when the last ice falls should match parameter 'd2'.
