Oven Thermocouple Kit, 11/01

PS555G and PS570G rear wall thermocouples with left-side terminal block connections

Thermocouples on these ovens are located on the rear wall. They are secured in place by two screws that are inserted through the holes in the thermocouple flange. The ovens are equipped with a three-lead, flanged thermocouple iden- tical to the one in this Kit.

NOTE FOR HIGH LIMIT THERMOCOUPLES:

These ovens have a high limit thermocouple installed in the last mounting hole at the exit end of the oven.

The thermocouple supplied in this Kit can be used to replace ANY of the temperature-sensing or high limit ther- mocouples on the oven.

1.Remove the rear shrouds. Then, remove the cover over the left blower motor. This allows access to the ther- mocouples on the rear wall, and to the terminal block inside the blower motor compartment.

Note that the thermocouples on these ovens are all connected to the terminal block inside the left blower motor compartment. It is not necessary to access the right blower motor compartment.

2.Remove the screws that hold the thermocouple to the wall. Slide the thermocouple out of its mounting hole.

3.Disconnect the thermocouple leads from the terminal block. Remove and discard the thermocouple.

4.Install the new thermocouple into its mounting hole. Fasten it in place with the supplied #6 x 3/8” screws.

5.Wire the thermocouple as shown in Figure 16. Note that the terminals are labeled - “TC” for temperature- sensing thermocouple leads, “G” for ground leads, and “HL” for high limit thermocouple leads.

6.Use the kit-supplied nylon clamp and #10-16 x 3/4” screw to secure the thermocouple leads so that they will clear the shrouds, blower belts, and pulleys.

7.Replace all shrouds onto the oven.
