Replacing the Oil Level Probes

The oil level probes monitor the oil level by temperature differences. If they becomes disabled, the display shows: “E-18A”= left probe; “E18-B”= right probe; “E18C”= both. Also, if any of the probes are out of calibration more than 10°F, or 10°C, the temperature probe should be replaced. (See Tech Mode for probe calibration steps.) An Ohm check can be performed also. See chart below.

To avoid electrical shock or property damage, move the power switch to OFF and disconnect power.

Remove control panel and hinge it down.
Referring to the decal on the rear of the control panel, locate the 12-pin probe connector in the upper, right-hand corner. (An ohm chart is also shown on the decal.)
Pull the connector from the panel and using a multimeter, take an ohm reading on the appropriate Level Probe pins. If ohm reading is significantly different than what is shown in RTD Resistance Chart continue with replacement procedure.

Replacing

Pull-out on the drain knob and drain oil from vat.
Using a 1/2 inch wrench, remove the nut on the compression fitting, and remove the temperature probe from the vat.
Using a terminal extractor, remove the probe terminals from the connector and remove probe from unit.
Place the nut and new ferrule on the new temperature probe and insert the temperature probe into the compression fitting.
Locate temperature probe through vat wall.
Place gauge against vat wall as shown.
Push temperature probe through until it makes contact with gauge.
Excess force will damage the temperature probe.
Tighten temperature probe in place.
Connect new temperature probe to the connector and fasten connector onto control panel.
Replace control panel and reconnect power to vat.
Fill vat by pressing and holding the filter button until *FILTER* *MENU* shows in the display. Then once “1.EXPRESS FILTER” shows in the display, press the right arrow button 4 times until “5.FILL FROM PAN” shows in the display. Press √ button and “PUMP” “EXIT” shows in the display. Press √ button again, and oil fills vat. Once vat is full, press X twice to return to normal operation.
