Just hooked up my GBF -10+TSRS-ETL and the touch screen is faintly blink but not displaying anything. Is the display faulty or is there another problem

Yes, the display is likely faulty. According to the information, if all connections are present but the display does not work, it indicates a faulty keypad or display. A faintly blinking screen without any display suggests it is not functioning correctly.

My compressor doesn’t start

The compressor of the Desmon GBF-3GN2/3 may not start due to the following reasons:
1. Er0 (Room Probe Failure) – The unit does not allow cycling; if running, it will stop. 2. Er1 (Evaporator Probe Failure) – During storage cycle, evaporator fans do not run, which may prevent compressor operation. 3. Er3 (Needle Probe Failure) – If running a needle probe set temperature cycle, the unit will stop. 4. HP (High Discharge Pressure or Low Suction Pressure) – The unit will not operate in any cycle; compressor, evaporator, and condenser fans stop. 5. d-r (Door Open Too Long) – Compressor and condenser fan stop if the door is open for more than the set time (P39). 6. Err (Motherboard-Keyboard Connection Failure) – May cause operational issues. 7. Res (Power Failure During Cycle) – May interrupt compressor operation. 8. P21 (Minimum Compressor Shut-down Time) – If the minimum time has not passed, the compressor will not restart.
These issues can prevent the compressor from starting or cause it to stop during operation.
