hello alan ive had a quick look and i think it might be a thermistor fault or a problem with the charge in the sytem affecting the thermistor check the resistance according to the service manual temp resistance value given in a graph or table reading within the tech book

hello alan found the tech book on the pu30ek online the tech manual says that its a th3 fault the thermisor is connected to the heat exchanger your head pressure could be too high dirty condenser fan coil or maybe you have a shortage of gas hope this helps if you need the tech book send me a message and give me your email address then i will send it too you
