If not present, replace computer. Motor is running at wrong speed (i.e. average time for three individual buns to pass through toaster is NOT between 15 and 18 seconds). A. Toaster improperly configured for power supply. A. Check data plate for voltage rating, and verify that power supply and toaster match. A. Improper power-supply. A. Verify that the power supply is 20 amp single-phase 200, 208 or 240VAC (depending upon model). Platen heats, but unit does not reach setpoint. B. Failed temperature probe. B. Use a temperature-measuring device to determine actual platen temperature. If measured temperature is within 10 degrees of the temperature displayed on the computer and the probe resistance at pins 3 and 5 of the 9-pin connector does not correspond to the appropriate value in the probe resistance chart on Pages 24 and 25, replace the probe. C. Failed computer. C. Use a temperature-measuring device to determine actual platen temperature. If measured temperature is within 10 degrees of the temperature displayed on the computer and probe resistance at pins 3 and 5 of the 9-pin connector corresponds to the value in the probe resistance chart on Pages 24 and 25, replace the computer. 1-7 PROBLEM PROBABLE CAUSES CORRECTIVE ACTION Platen does not heat, but computer display is on. A. Failed computer. A. Check for 12VDC on computer pins 6 & 7. If NOT present AND motor is running, replace computer. Check for 5VDC on terminals 3 & 4 of main heater relay and pins 1 and 6 of computer. If NOT present at either point AND motor is running, replace computer. B. Broken/loose wire between computer and latch relay, or failed latch relay. B. Check for 12VDC on computer pins 6 & 7. If present and wiring is intact, replace latch relay. C. Failed main heater probe. C. Determine temperature of platen then measure main heater probe resistance at pins 3 & 5 of 9-pin connector. If the probe resistance is NOT approximately equal to the corresponding resistance in the chart on Pages 24 and 25, replace the probe. D. Broken/loose wire between computer and main heater relay, or failed main heater relay. D. Check for 5VDC on terminals 3 & 4 of main heater relay AND on computer pins 1 & 6. If present on pins 1 & 6, but NOT on terminals 3 & 4, and wiring is intact, replace the main heater relay. E. Failed platen. E. Check for 5VDC on terminals 3 & 4 of main heater relay and for line voltage on terminal 2 of main heater relay and terminal 4 of latch relay. If expected voltage is present at all three points, replace the platen. Probe Resistance Chart For use with CT16 Series toasters manufactured with Minco Thermistor probes only.
