If the evaporator heater in your Panasonic Chiller isn't working: * Check the main fuse and the auxiliary fuses, as there may be no power supply. * Check the heater and replace it if required, as the heater circuit may be open.
Why is there no control over water temperature in my Panasonic 140?
If you have little to no control over the water temperature in your Panasonic Chiller: * Check the temperature setting on the control panel, as the thermostat setting may be incorrect. * Check the water flow and the quantity of liquid in the water circuit, as there may be an incorrect temperature differential between evaporator inlet and outlet.
What to check if my Panasonic 140 unit is not operating with no alarm activation?
If your Panasonic Chiller isn't running and there's no alarm: * Check the pump for water circulation fault. * Check the flow controller. * Check the differential pressostat.
What to do if my Panasonic 140 Chiller compressor does not operate?
If one or both compressors of your Panasonic Chiller aren't working, several issues could be the cause: * An electrical circuit cut. Check the electrical circuit for grounding or short-circuits and inspect the fuses. * The high pressure pressostat activated. Reset the pressostat from the control panel and restart the unit. Identify and eliminate the causes of this activation. * Control circuit fuse blown. Check the control circuit for grounding or short-circuits and replace the fuses. * Connection problem. Check the tightness of all the electrical connection terminals. * Electrical circuits thermal protection cuts in. Check the operation of the control and safety devices and identify/eliminate the cause of the activation. * Incorrect wiring. Check the wiring of the control and...
