6.6.2 Replacing the Temperature Probe

1.Unplug the rethermalizer and drain the cookpot.

2.Remove the screws from the upper corners of the timer panel and swing the panel open from the top, allowing it to rest on its hinge tabs. Cut the probe leads off at the rear of the probe. NOTE: Once the probe leads have been cut, the probe cannot be reused. Work the Tinnerman retaining clip rearward off the probe.

3.Remove the two screws securing the probe cover to the probe block and remove the cover. Slip the failed probe out of the block from the cookpot side and replace with a new probe. Carefully remove the Tinnerman retaining clip from the replacement probe to allow the leads and short end of the probe to be inserted through the probe block from cookpot side. When the replacement probe has been inserted, work the retaining clip onto the probe until the probe is held securely in place. Reinstall the probe cover and timer panel.

4.Remove the screws from the upper corners of the control panel and swing the panel open from the top, allowing it to rest on its hinge tabs. Remove the two upper screws securing the compo- nent box to the rethermalizer. Rotate the box forward and outward to expose the 12-pin connec- tor on the rear of the interface board.

5.Unplug the 12-pin connector from the interface board. Using a pin pusher, remove the cut off pieces of wire from the connector one at a time, and insert the corresponding wire from the new probe.

6.Reattach the 12-pin connector to the interface board, rotate the component box back into posi- tion, and replace and tighten the mounting screws. Close the control panel and replace the screws in each upper corner.
