when i switch on the above condensor dryer, the clean filter light comes on, on every prog its set to. when the start button is pressed, it just beeps 3 times. ele, stats, switches, etc ok. i think its got to be the pcb. has anyone else had this fault just to confirm? and also, do these pcb’s need programming if i was to get one as electrue say they’re unprogrammed. any help would be good. thanks
