Temperature sensor failure
Check all terminal connections between the
temperature sensor (thermocouple) and temperature
controller (301). It is recommended to loosen then
tighten the screws in the terminal blocks in case the
connections are oxidised.
If this does not correct the error then replace the
furnace or oven temperature sensor (thermocouple).
