Did the connector for the
liquid pipe temperature sensor
break away from the PCB?
Did the resistance value
significantly stray from the following
temperature table?
Separate the connector of the liquid pipe
temperature sensor from the PCB and measure
the resistance value between the two terminals.
Restart operation after changing PCB
Restart operation after connecting
