Problem Solution
No heat 1. Is the display on the temperature controller on? If
not, check for 220 Volts on terminals 9 and 10. If
there is voltage, replace the temperature
controller.
2. If the display is on and SV is set higher than PV, is
there a red light on? If not, replace the
thermocouple.
3. If there is a red light on, check for 220 VAC from
any wire number 8 to terminal 13, and then
terminal 14. If no voltage, replace the temperature
controller.
4. If there is 220 VAC, check for 220 VAC on coil of
heater contactor. If there is voltage and the
contactor is not pulling in, replace contactor.
5. If there is no 220 VAC, check heater bank on / off
switch. The best way to check this is to disconnect
the wires and check resistances (Ohms).
