Hi all,
Briefly looked at the above ice machine today. Last engineer had a iced up evap and he cleared it and was ok for a day or 2. This happened in the last week. I got there today and was bleeping twice to indicate defrost took over 20 mins. Reset PCB and unit came on but stayed on defrost. Hot gas sol valve and compressor are ok so pretty sure the thermistor on suction pipe is out. When i checked the thermistor and removed from pipe clamp the defrost cycle stopped and made a batch of ice.
Anyone know what value the thermistor should be reading on ohmmeter at different temps?
also is this thermistor involved in ice production or is that done by pcb on this model?
Many thanks in advance
