Hi guys i have a foster PREM 1/4 4 door bench freezer. Soon as the cabinet is switched on the alarm beeps with "Probe 1 fault", the cabinet has 3 probes, air,evap and condensor. The probes are LAE. I replaced probe 1 and still the same fault came up on switch on, i tried juggling the probes about swapping them over and still "probe 1 fault", i phoned foster tech support and they told me it must be a PCB fault so i ordered a new pcb and fitted it today and still probe 1 fault appears on the screen, all the ribbon cables are inserted into the controller etc the right way round. Now with the new pcb on when i check probe temperatures on the left display it is showing question marks and no readings so i am not getting any probe readings now? anyone had a similar problem or any advice?? Thanks in advance!
